All Rights Reserved. Proprietary and Confidential 5/16/2013 ITCR Wayside Users Manual 1. Overview This document provides information required for the operation and verification of the Meteorcomm Interoperable Train Control Radio Network (ITCR) Wayside radios. 1.1 Applicable Radio Models and Identifiers This document applies to the Wayside radio model listed below along with its regulatory identifiers. Model: 63010 FCC ID: BIB63010 IC: 1300A-63010 1.2 General Description The Wayside radio is designed to satisfy the industry standard Positive Train Control
(PTC) requirements as part of an integrated 220 MHz radio network. The Base radio, Locomotive radio, and Wayside radio form the transportation backbone on which a messaging application provides communication capabilities between railroad assets and their back offices. The ITCR is designed to provide communication in an inter-
operable fashion enabling messaging to occur across railroad boundaries. When applied as a mobile station, this radio will be mounted in mobile maintenance vehicles such as pickup trucks. It will actively join the ITC network only when maintenance vehicles are driven on the rails. The Wayside radio is normally positioned on railroad property in an equipment box or bungalow close to the active rails. When used as a wayside station, its mission is to provide wireless transmission of local track and trackside equipment where it is mounted. Its radio messages are actively monitored by locomotives in the vicinity that may be headed in its direction. It also normally associates with a nearby base station. The base station backhauls the wayside transmission for various monitoring and control purposes at the railroad central office. It is normally interfaced to a Wayside Interface Unit (WIU) via its LAN ethernet port. The WIU terminates all local wayside equipment such as switches, signals, track continuity circuits and several 5/16/2013 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 1 ITCR Wayside Users Manual other possible track condition indicators. The WIU formats the status information into a short message called an aspect. The aspect is sent to the Wayside radio for packetized RF transmission. 1.3 Chassis Wayside radios are housed in electrically sealed metal cases. The Wayside radio dimensions are approximately 15.5W X 9.5 H X 2.0D. It weighs less than 8 lbs. All input/output ports are grounded and/or shielded. In addition, best engineering practices have been employed with respect to internal shielding, unit assembly and PCB design in an effort to minimize potential sources of unwanted radiated emissions. 1.4 Ports and Ethernet Connectors The Wayside radio has two RJ45 Ethernet I/O ports, marked LAN and MAINT, each on its own network. 1.5 Power Connectors The Wayside radio power input connector is a Wago type for 13.6 VDC nominal, min 10.9 VDC and max 15.5 VDC. 1.6 Antenna Connectors The 30W PEP rated 220-222 MHz wayside radio transmitter has an N-type antenna connector and expects a nominal 50 ohm resistive load, max VSWR 3:1. It also has a TNC connector for the GPS antenna. The GPS antenna can be active (3.3Vdc, 50mA max) or passive. 2. Important Information for the User 2.1 Transmitter Warm-Up Period. The wayside transmitter uses a temperature compensated crystal oscillator (TCXO) to achieve frequency accuracy and stability. No warm-up period is required beyond the built-in radio startup delays. 2 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 5/16/2013 ITCR Wayside Users Manual 2.2 Limiting RF Exposure Please refer to the RF Energy Exposure Guide packed with each radio for specific information regarding safe distances that must be maintained between personnel and energized transmitting antennas. The information in the RF Energy Exposure Guide is determined from FCC and Industry Canada rules that when followed, limit human exposure to radio frequency energy to acceptable levels. Note that the RF Energy Exposure Guide calculates the larger lateral safe distances for an uncontrolled environment. Obeying these limits will protect both railroad employees and the general public. This radio is intended for use by railroad employees who have full knowledge of their exposure and can exercise control over their exposure to meet FCC and IC limits. This radio device is not intended for use by consumers or the general population. This transmitter is intended to be operated with a fixed or mobile antenna in an Occupational/Controlled Exposure environment per FCC OET 65 or Controlled Use Environment per IC RSS-102. Maximum Permitted Exposure (MPE) limit for devices in the presence of the general public in the 100-300 MHz range is 0.2 mW/cm2 = 2 W/m2. The tables in the RF Energy Exposure Guide list the calculated lateral distances to be maintained between the general public and an operational Wayside transmitter antenna for two antenna types and gains and for both fixed and mobile applications. The transmitter power is adjustable to accommodate the various installations of this product. Once the authorized ERP, antenna gain and the losses from feed line, connectors and any inline RF filters are known, the transmitter power must be evaluated and if necessary, set to a value that will ensure that the authorized ERP and RF exposure requirements are met. Example ERP calculations are provided further below. 2.3 Antenna Guidelines This section contains antenna information and additional notes regarding methods to limit RF exposure. 5/16/2013 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 3 ITCR Wayside Users Manual The licensee is required to comply with limits on antenna location, power and effective antenna height per 47CFR Subpart T 90.701 et. seq., or Industry Canada SRSP-512 6.3 as applicable. Install antennas in accordance with the manufacturers instructions. Disable the transmitter when installing or servicing its antenna or transmission line. Refer to the RF Energy Exposure Guide for specific guidelines regarding the siting and installation of mobile and fixed antennas. Acceptable mobile and fixed antenna types are listed in the tables in the RF Energy Exposure Guide. Unauthorized antennas, equipment modifications or attachments could invalidate any equipment warranty or authority to transmit. Modification could damage the radio and may violate FCC or IC regulations. Contact Meteorcomm before using other antennas. Maintain a safe distance from energized transmitting antennas. See above. 2.4 RF Interference to Residential Receivers (Part 15) NOTICE TO USER: This device complies with part 15 of the FCC Rules.

Proprietary and Confidential 5/16/2013 ITCR Wayside Users Manual 2.5 Equipment Modifications Caution: Any changes or modifications to this equipment not expressly approved by the party responsible for compliance (in the respective country of use) could void the users authority to operate the equipment. 3. Wayside Transmitter Operation It is the responsibility of the licensee to operate this radio transmitter in compliance with the terms of the license and FCC or Industry Canada service rules for 220-222 MHz, i.e., FCC Rules Part 90T and Industry Canada SRSP-512, or in the U.S. only, operation on 217.6-218 and 219-220 MHz frequencies is subject to FCC Rules Part 80. 3.1 Wayside Channelization and Frequency Range The Wayside radio can be configured to transmit on any one of 80 selectable 25-kHz spaced channels ranging from 220.0125 to 221.9875 MHz inclusive. The spectrum included corresponds to all 5 kHz wide FCC channels numbered from 1 at 220.0025 MHz to 400 at 221.9975 MHz. Each wayside transmission occupies five of the FCC-
defined 5 kHz channels. The lowest Wayside radio channel center frequency is in the center of FCC channel 3 and the next is FCC channel 8, then 13, 18, etc., up to the highest in the center of channel 398. In the USA only, the radio can be licensed and configured to operate on 56 additional (Part 80) frequencies in the ranges 217.6125 to 217.9875 MHz and 219.0125 to 219.9875 MHz. 3.2 Wayside Channel Restrictions Section 90.715 of the FCC Rules lists the authorized frequencies of the 400 total 5 kHz-wide channels. According to 90.733(d) these can be aggregated into larger channel widths with the exception of FCC channels 161-170 and 181-185. 5/16/2013 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 5 ITCR Wayside Users Manual Therefore, the wayside radio may not transmit on those channels or their 221 MHz counterparts, 361-370 and 381-385. This corresponds to wayside frequencies, 220.8125, 220.8375, 220.9125, 221.8125, 221.8375, and 221.9125 MHz. Please refer to Part 90 Subpart T and SRSP-512 for additional frequency use restrictions in Canadian and Mexican border areas. 3.3 Wayside Radiated Power Limits It is the responsibility of the licensee to comply with the effective radiated power limits based on operating frequency, geographic location, and effective antenna height set out in 47CFR Subpart T 90.701 et. seq., or Industry Canada SRSP-512 6.3, as applicable. Important: The following supplementary antenna system information discusses means for the licensee to determine effective radiated power (ERP) and comply with regulatory power limits. Licensees must comply with the specific power and antenna height limitations for fixed-antenna stations per 90.729 or SRSP-512 6.3. Note that U.S. and Canadian power limits vs. HAAT are not identical. Licensees should note that all mobiles and also fixed installations transmitting between 221 and 222 MHz must limit effective radiated power (ERP) to 50W or 10*log(50) + 30 = 47dBm PEP referenced to the 2.15 dBi gain of a dipole, unless operating under a waiver of FCC rule 90.729(b) or SRSP-512 6.3 as applicable. The EIRP for this case is 49.15 dBm. Also note that the maximum ERP on FCC/IC channels 196-200 at 220.975 to 221.000 MHz is 2 watts. The allowable transmitter peak envelope power output in dBm is determined by subtracting the antenna gain in dBi from 49.15, then adding the loss from the antenna feedline and connectors. If the result is greater than or equal to 44.85 dBm
= 14.85 dBW then the maximum power output of the Wayside transmitter can be used. If the value is less than 44.85 dBm, then the transmitter output power must be reduced to the calculated value. Mobile Installation: As an example of a mobile installation, consider a vertical half wave ground plane on a vehicle metal rooftop. In an ideal installation the antenna gain = 2.4 dBd = 4.55 dBi. Ignoring connector losses, feedline loss is at least 0.6 dB 6 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 5/16/2013 ITCR Wayside Users Manual for 10 feet of Times Microwave LMR-195 Ultra Flex coaxial cable. Transmitter power output limit = 47-2.4+0.6 = 45.2 dBm PEP and therefore the system is compliant with the 50W ERP limit. The actual ERP in this case is 10^(14.85+2.4-0.6) = 46.2 W. This installation is not allowed to transmit on FCC channels 196-200 because the maximum ERP is greater than 2 watts. Fixed Installation: In a fixed installation, a common single-element exposed folded dipole antenna without reflector has 0 up to 2.9 dBd (2.1 to 5.0 dBi) azimuthal gain depending on the design. Once the allowable ERP is determined by applying all power-restrictive rules from above and the antenna gain is known, the transmitter peak envelope power output feeding the transmission line is determined by subtracting the antenna gain in dBd from the ERP and adding the loss from the antenna feedline and connectors plus the loss from any external inline power sensors, combiners, filters or lightning arresters. If the net value is greater than or equal to 44.85 dBm, then the maximum power of the Wayside transmitter can be used. If the value is less than 44.85 dBm, then the transmitter output power must be reduced to the net value. Example for the 50W ERP fixed case: Antenna gain = 2.9 dBd and feedline loss is at least 0.5 dB for 25 feet of Times Microwave LMR-400 coax plus 0.4 dB for inline lightning arrester and three connectors. Assuming no other losses, the transmitter power output limit = 47-2.9+0.9 = 45 dBm PEP. In this case, the actual Wayside ERP is 44.85+2.9-0.9 dBm = 46.85 dBm = 48.4 W PEP and therefore the system is compliant with the 50W ERP limit. This installation is not allowed to transmit on FCC channels 196-200 because the maximum ERP is greater than 2 watts. 4. Setup and Configuration for the Wayside Radio Set up physical connections with the following:
DC Power Ethernet RF output termination The sections below identify each of the physical connections. 5/16/2013 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 7 ITCR Wayside Users Manual 4.1 Power Supply Wayside radios operate at 13.6Vdc input. Table 1 describes the power supply requirements. Caution: Applying an incorrect voltage to a Wayside radio can cause damage. Confirm the voltage of the radio and the power supply before applying power. Table 1 Wayside Radio Power Parameters Parameter Nominal DC Power Input Voltage Operational Range Damage limit Current Drain (while transmitting rated power) 4.2 Ethernet Connection Wayside Radio 13.6Vdc 10.9-15.5Vdc (+14%/-20%) 17Vdc 10A max while transmitting into 50 ohm load Wayside radios use a standard CAT5 Ethernet cable connected between a PC and the maintenance port of the radio. Configure the PC network card with a fixed IP address of 10.10.1.254. You will use XtermW, a Meteorcomm terminal emulation program, to connect with and control the radio via commands issued at command prompts. 4.3 RF Output Termination The Wayside radio is rated for 30W PEP. Sufficient termination is required to protect test equipment. For transmitter and receiver testing, connect the test equipment to the port labeled ANT. See further instructions below. 8 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 5/16/2013 ITCR Wayside Users Manual 5. Tuning the Wayside Radio There are three parameters to test and potentially tune before/during RF testing:
Master reference crystal oscillator frequency RF output power RF output channel Factory technicians tune the master reference crystal oscillator and set the RF gain for maximum rated output power. You may have to adjust the three parameters before or during RF testing by entering commands using XtermW or another terminal emulation program. 5.1 Equipment Required 1. 2. 10A DC power supply at rated voltage of wayside radio, nominally 13.6 VDC. Personal computer with Ethernet network adapter and Meteorcomm XtermW or equivalent terminal program installed. 30 dB 50W RF power attenuator. 3. 4. Vector spectrum analyzer for power and frequency measurements. 5. Optional 8+ digit frequency counter for frequency measurements. 6. High stability time base accurate to 0.1 ppm. Can be internal to items 4 and 5. 5.2 Set up the Radio for Testing 1. Adjust a 10A DC power supply to 13.6 VDC and then disable its output. Observing polarity of the power supply terminals, connect the wayside power cable between the radio power connector and the power supply. 2. Connect one end of a CAT5 ethernet cable to the RJ-45 radio port labeled MAINT. Connect the other end to a computer network card. The default radio IP address is 10.10.1.254. Set the IP address of the computer network card to a compatible fixed address such as 10.10.1.1. The computer should have Meteorcomm XtermW or a similar terminal emulation program installed. 5/16/2013 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 9 ITCR Wayside Users Manual 3. Apply power to the radio. Wait 30 seconds to open an XtermW session. Use the Edit/Configure Port window to set Port Type = TCP/IP, Protocol = Stream, TCP/IP Settings Host = 10.10.1.254, Port 4000. Select Device Type = MCC 6100 SDR (which also applies to ITC radios). Return Character = CR, Data Format =
ASCII. 4. Attach a 50W 30 dB RF attenuator to the TX/RX1 N-type antenna connector. Attach an (e.g., Agilent MXA or PXA) vector spectrum analyzer or similar to the transmitter port for power and frequency measurements. The VSA should contain either a precision stability reference oscillator or attach an external rubidium reference to the VSA external reference input. 5.3 Measure and Calibrate Reference Crystal Oscillator Frequency The instructions below allow you to change the factory calibration settings for the master reference oscillator crystal. To check the master reference crystal oscillator frequency calibration:
1. Open an XtermW session. 2. Put the radio into test mode by typing:
dsp,watchdog,off dsp_mode,test 3. Reduce output power to approximately 2W by typing:
cal,set,ddslevel, 100 4. Begin transmitting a test tone directly on the carrier frequency:
l1_test,stop l1_test,set,txmod,cw l1_test,set,txfreq,220012500 l1_test,start,tx 5. Use the frequency counter or frequency counting marker on the VSA to measure the output frequency. The measured value is the actual carrier frequency. The carrier frequency is normally well within 352 Hz (1.5 ppm) of the center frequency of the channel. 6. Alternate to the test tone: Substitute the following /4-DQPSK modulation command for the second line in step 4. l1_test,set,txmod,dqpsk_half 10 2013 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential 5/16/2013 ITCR Wayside Users Manual 7. Set the VSA to the center frequency of the channel and set it to demodulate the 8 ksym/second /4-DQPSK emission and measure the error frequency which is referenced to the VSA center frequency. To adjust the master crystal reference oscillator parameters:
1. First, check the factory default setting for the crystal reference parameter by typing cal 2. Note the value for xo in the cal factors table that is displayed. 3. At the XtermW command line, type:
cal,set,xo,xx where xx is some value close to the original factory set value. 4. Use trial and error to determine the set point for the xo value to achieve the desired carrier frequency accuracy. To reset the XO tuning parameter to the factory setting:
Power cycle the radio. 5.4 Measure and Adjust Output Power Caution: Avoid unnecessary adjustments. Exercise caution when setting DDS level (ddslevel) or other power output controls as damage to the radio can occur if they are set too high. The wayside radio is rated for 30W PEP and is preset to this level at the factory. If additional tuning is required, use an appropriate method to measure PEP for a /4-
DQPSK signal. The CCDF function on the VSA is recommended for peak power measurement. Slowly increase/decrease ddslevel level from its nominal set point, as determined by issuing the command cal. To measure and adjust output power:
1. typing:

RF Energy Exposure Guide for Meteorcomm PTC Radios Installed in Vehicles or at Fixed Sites IMPORTANT BEFORE INSTALLING, MAINTAINING OR USING YOUR RADIO, READ THIS GUIDE WHICH CONTAINS IMPORTANT RF ENERGY AWARENESS AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE WITH FEDERAL COMMUNICATIONS COMMISSION OR INDUSTRY CANADA RF EXPOSURE GUIDELINES. IMPORTANT RETAIN THIS GUIDE AT THE LOCATION OF THE RADIO RF Energy Exposure Awareness and Control Information, and INSTALLATION. Operational Instructions for FCC/IC Occupational Use Requirements NOTICE: This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC/IC limits. This radio device is NOT authorized for general population, consumer, or any other use. This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses RF energy or radio waves to send and receive messages. RF energy is one form of electromagnetic energy. Other forms include, but are not limited to, sunlight and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which when used improperly, can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. Experts in science, engineering, medicine, health, and industry work with organizations to develop standards for safe exposure to RF energy. These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection. All two-way radios marketed in North America are designed, manufactured, and tested to ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of two-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following Web sites for more information on what RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits. http://www.fcc.gov/oet/rfsafety/rf-faqs.html MCC PTC Radio RF Energy Exposure Guide 1 v9 10/21/2011 http://www.osha.gov/SLTC/radiofrequencyradiation/index.html FCC/ Industry Canada Regulations The FCC/IC rules require manufacturers to comply with the FCC/IC RF energy exposure limits for mobile two-way radios before they can be marketed in the U.S. or Canada as applicable. When two-way radios are used as a consequence of employment, the FCC/IC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Your MCC user manuals and this RF Energy Exposure Guide include information and operating instructions required to control your RF exposure and to satisfy compliance requirements. Compliance with RF Exposure Standard Your MCC two-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty factors as shown in Tables 1 and 2 and is authorized by the FCC/IC for occupational use. In terms of measuring RF energy for compliance with the FCC/IC exposure guidelines, your radio antenna radiates measurable RF energy only while it is transmitting, not when it is receiving or in standby mode. Your MCC two-way radio complies with the following RF energy exposure standards and guidelines as of the date of manufacture:
U. S. Federal Communications Commission, Code of Federal Regulations; 47CFR Part 2 Subpart J Industry Canada RSS-102 Issue 4. American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992 Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition MCC PTC Radio RF Energy Exposure Guide 2 v9 10/21/2011 Mobile Installations: RF Exposure Compliance, Control Guidelines and Operating Instructions to ensure compliance with To control exposure occupational/controlled environment exposure limits, always adhere to the following procedures. 1. to yourself and others and Guidelines:
These user awareness instructions should accompany the device or vehicle that it is installed in when transferred to other users. Do not use this device if the operational requirements described herein are not met. 2. Operator Instructions:
Be aware that a transmitter may operate automatically at any time when functioning as a data radio. People outside of the vehicle must maintain the recommended minimum lateral distance from the antennas at all times. It is the responsibility of the vehicles operator to keep bystanders beyond the minimum lateral distance from the antennas in order to comply with the FCC RF exposure limits for an uncontrolled/general population environment. Verify that people outside the vehicle are at least the recommended minimum lateral distance away, as shown in Table 1, from a properly installed externally-mounted antenna. The transmitter power is adjustable to accommodate the various installations of this product. Once the authorized ERP, antenna gain and the losses from feed line, connectors and any inline RF filters are known, the transmitter power must be evaluated and if necessary, set to a value that will ensure that the authorized ERP and RF exposure requirements are met. Refer to the user manual for the particular radio model for additional information regarding power adjustment. Table 1 below lists the recommended lateral distances to be maintained between bystanders and approved, properly installed mobile transmitting antennas in an uncontrolled environment.
