DataNex EMS Wireless, DATA-20 Digital Radio System Description 1-4 1.5 System Description (QAM) 1.5.1 Introduction The product is a full-duplex digital radio. The following sections describe the TX system, RX system, followed by sub-system components. Please reference the accompanying block diagrams for clarification. We will follow the typical end-to-end progression of a radio system starting with the TX baseband inputs, to the QAM modulator, followed by the upconversion process and the power amplifier. We then proceed to the RX preamplifier input, the downconversion process, followed by the QAM demodulator and baseband outputs.

. All modules (excluding the Front Panel and Power Amplifier) are interconnected via the backplane that traverses the entire width of the unit. The backplane contains the various communication buses as well as the PA (Power Amplifier) control and redundant transfer circuitry. The power supply levels and status are monitored on the backplane and the NMS/CPU card processes the data. DataNex EMS Wireless, DATA-20 Digital Radio 1-5 System Description Figure 1-4. Location of theDATA-20Backplane and Power Amplifier The NMS/CPU card incorporates microprocessor and FPGA logic to configure and monitor the overall operation of the system via front panel controls, LCD screen menus, status LEDs and the bar graph display. Module settings are loaded into the installed cards and power-up default settings are stored in non-volatile memory. LCD screen menu software is uploaded into memory, providing field upgrade capability. A Windows-based PC interface is available for connection at the rear panel DATA port. 1.5.2 QAM Modulator/IF Upconverter INTERLEAVE RAM IF OUT QAM ENCODER LED STATUS IF REF CLK OUT TRUNK I/O LEVEL TRANSLATOR TXD RXD RS232 TRANSLATOR IF IN AGC QAM DECODER INTERLEAVE RAM DATA & CLK BUS IN BUS REF CLK OUT NCO DIGITAL POT OCXO 12.8 MHz IF STATUS BUS I2C IN MICRO CONTROLLER SPI DEBUG IF SYNTH FPGA FPGA EEPROM uC EEPROM DATA & CLK BUS OUT RATE CONVERTER LEGEND PLL FIFO NO CONNECTION uC BUS REF CLK Figure 1-5. QAM Modem Block Diagram The QAM (Quadrature Amplitude Modulation) Modulator is the transmit portion of the QAM Modem card. The QAM Modem also houses the IF Up/Down Converter. The QAM Modulator utilizes the upconverter portion of the IF daughter card. The QAM Modulator accepts the aggregate data stream via the backplane (see Figure 1-5 above). The module performs modulation at a carrier frequency of 6.4 MHz, adding FEC
(Forward Error Correction) bits while interleaving the blocks of data. The result is a very spectrally efficient, yet robust linear modulation scheme. This process requires an ultra-stable DataNex EMS Wireless, DATA-20 Digital Radio System Description 1-6 master clock provided by an OCXO (oven controlled crystal oscillator) that is accurate to within 0.1 ppm.

RF Upconverter Block Diagram The IF output carrier of the IF Upconverter daughter card is fed to the transmit portion of the RF Module via an external (rear panel) semi-rigid SMA cable. This module performs the necessary upconversion to the RF carrier (see Figure 1-7). There is an on-board CPU for independent control of the critical RF parameters of the system. Since this is a linear RF processing chain, an automatic leveling control loop (ALC) is implemented here to maintain maximum available power output (and therefore maximum system gain). The ALC monitors the PA forward power (FWD) output sample, and controls the upconverter gain per an algorithm programmed in the CPU. The ALC also controls the power-up RF conditions of the transmitter output. 1.5.4 Power Amplifier (PA) The Power Amplifier (PA) is a separate module that is mounted to a heat sink and is fan-cooled for reliable operation. The PA is a design for maximum linearity in an amplitude modulation-

The QAM Modem also houses the IF Up/Down Converter. The QAM Demod utilizes the downconverter portion of the IF daughter card. The IF Downconverter receives the 70 MHz carrier from the receiver portion of the RF Module via an external semi-rigid cable and directly converts the carrier to 6.4 MHz by mixing with a low-
noise phase-locked LO (see Figure 1-9). System selectivity is achieved through the use of a 70 MHz SAW filter. The QAM Demod receives and demodulates the 6.4 MHz carrier (see Figure 1-7). The demodulation process includes the FEC implementation and de-interleaving that matches the QAM modulator in the transmitter, and the critical data assisted recovery of the clock. This process requires an ultra-stable master clock provided by an OCXO (oven controlled crystal oscillator). The output is an aggregate data stream that is distributed to the trunk port for if the data input/output is out of the Modem, or to the backplane for connection to the multiplexer connected on the backplane.

The main bus voltages (+5 and +/-12) are summed in the backplane and provide the supply the plug-in modules. NOTE:
The front panel LCD screen displays the system supply voltages and the nomenclature follows the physical location of the power supply modules. 2.6.2 AC Line Voltage The DATA-20 uses a high reliability, universal input switching power supply capable of operating within an input range of:
100 - 240 VAC; 50/60 Hz The power supply module is removable from the unit and a perforated cage protects service personnel from high voltage. The power supply is fan cooled due to high power consumption by the PA. CAUTION High voltage is present when the unit is plugged in. To prevent electrical shock, unplug the power cable before servicing. Power supply module should be serviced by qualified personnel only. DataNex EMS Wireless, DATA-20 Digital Radio Installation 2-6 2.6.3 DC Input Option An optional DC input power supply is available for the DATA-20; using high reliability, DC-DC converter(s) capable of operation within the following input ranges (dependent upon nominal input rating):
Nominal DC Input 24 Volt:
48 Volt:
Operating Input Range 20 28 VDC 32 64 VDC The DC input is isolated from chassis ground and can be operated in a positive or negative ground configuration. The power supply module is removable from the unit and no high voltages are accessible. 2.6.4 Fusing For AC modules, the main input fuse is located on the switching power supply mounted to the carrier PC board and the protective cage may be removed for access to the fuse. For DC modules, all fusing is located on the carrier PC board. Always replace any fuse with same type and rating. Other fuses are present on the board, and are designed for output fail-safe protection of the system. All output fuse values are printed on the backside of the PC board to aid in replacement. NOTE: If a fuse does blow in operation, investigate the possible cause of the failure prior to replacing the fuse, as there is adequate built-in protection margin. 2.7 Power-Up Setting As shipped, the DATA-20 will radiate into the antenna upon power-up, THIS ASSUMES THAT THE ANTENNA LOAD IS GOOD (LOW VSWR). If the VSWR of the load causes a high reverse power indication at the PA, the red VSWR LED will light and the transmitter will cease radiating. This is called the AUTO setting in the QAM RADIO CONTROL screen (see below). The LCD screen (QAM RADIO TX CONTROL) selects the power-up state and controls the radiate function of the TX unit. Go to the MAIN MENU:

This consists of twoDATA-20 chassis with a TP64 transfer panel (Figure 2-5) Transfer Panel Connection The usual hot standby configuration uses an external duplexer. This minimizes RF losses and provides independent TX and RX module switching. A duplexer should already be mounted on the TP64 chassis. Alternatively, rack mounted duplexers (typical for tighter channel spacings) may be provided. The connections are the same, although the physical location is different. A power divider (used to split the signal equally to two receivers) is required in this mode. The input to the power divider connects directly to the duplexer with an N-N (male) adapter. See Figure 2-4 for installation details.

This is the preferred operating mode. Cold Standby Cold standby can be used in situations where lower power consumption is a priority. In this mode, the transfer logic will control the RADIATE function of each transmitter, turning the RF DataNex EMS Wireless, DATA-20 Digital Radio 2-11 Installation output ON (in tandem with the RF relay) as required for switching. This will increase switching time and a corresponding increase in data loss during the switchover. 2.9.2 Hot Standby Control using the TP64 2.9.2.1 TP64 Front Panel Controls and Indicators Note: See the following section for a detailed description of the Master/Slave logic implemented in the TP64.

The indicated module is active, and that the module is performing within its specified limits. The indicated module is in standby mode, ready and able for back-up transfer. There is a fault with the corresponding module. It is not ready for backup, and the TP64 will not transfer to that module. TRANSFER Switches The RADIO A and RADIO B transfer switches cause the selected radio to become active, and the Master. See Section 3.4 (following) for further details. 2.9.2.2 Master/Slave Operation & LED Status The TP64 operates in a Master/Slave logic mode. In the power up condition, the Master is RADIO A. This means that RADIO A is the default active unit. The following logic applies to hot or cold standby, external or internal duplexer configurations.

If RADIO A is good, the TP64 will remain in RADIO A position, regardless of RADIO Bs status. If RADIO A fails, the TP64 will switch to RADIO B (assuming that RADIO B is good) If RADIO A then returns to a good condition, the TP64 will switch back to RADIO A (the default Master) Manual Switchover to B-Master Logic The front panel switch on the TP64 can be used to manually force the system to a new Master. By pressing the RADIO B button, RADIO B now becomes the Master, and the TP64 will switchover to RADIO B (assuming that RADIO B is good). The default A-Master Logic will then switch to B-Master Logic, as outlined in Tables 2-3 and 2-4. DataNex EMS Wireless, DATA-20 Digital Radio 2-13 Installation Note: Manual switching of the Master is often used to force the system over to the standby unit. The user may want to put more time on the standby unit after an extended period of service. In Hot Standby configurations, this will not buy the user anything in terms of reliability. In Cold Standby, the burn time is more significant, since the RF power amplifier device operating life becomes a factor. 2.9.2.3 DATA-20 Software Settings The full array of available settings for the Control and Configuration menus are located in Section 3Operation of the Front Panel. Shown here are the applicable settings for redundant standby systems. Clock Settings For proper operation, the clock settings (located in the QAM Radio/Config/Modem Menu) must be set as follows:

A proper installation is usually preceded by a pre-installation site survey of the facilities. The purpose of this survey is to familiarize the customer with the basic requirements needed for the installation to go smoothly. The following are some considerations to be addressed (refer to Figure 2-8 for Site Installation Details). Before taking the product to the installation site verify that the interface connections are compatible with the equipment to be connected. Also, locate the information provided by the path analysis that should have been performed before ordering the equipment. At the installation site, particular care should be taken in locating the product in an area where it is protected from the weather and as close to the antenna as possible. Locate the power source and verify that it is suitable for proper installation. The installations should only be performed by qualified technical personnel only. DataNex EMS Wireless, DATA-20 Digital Radio Installation 2-16 2.11 Antenna/Feed System 2.11.1 Antenna Installation For compliance with FCC RF Exposure requirements the following has to be adhered to:-
1. All antenna installation and servicing is to be performed by qualified technical personnel only. When servicing the antenna, or working at distances closer than those noted below, ensure the transmitter has be disabled. 2. Typically, the antenna connected to the transmitter is a directional (high gain) antenna, fixed-mounted on the side or top of a building, or on a tower. Depending upon the application and the gain of the antenna, the total composite power could exceed 20 to 61watts EIRP. The antenna location should be such that only qualified technical personnel can access it, and that under normal operating conditions the antenna separation from the user is required to be located at the distance of 3.5meters or more. EIRP at the antenna is calculated as follows:-
Transmit power Cable loss + Antenna Gain = EIRP Eg.

LCD display (including all screen menus) Cursor and screen control buttons LED status indicators 3.2 Front Panel Operation A picture of the DATA-20 front panel is depicted in Figure 3-1 below. Front Panel Operation 3-2 Figure 3-1.DATA-20 Front Panel 3.2.1 LCD Display The Liquid Crystal Display (LCD) on the DATA-20 front panel is the primary user interface and provides status, control, configuration, and calibration functionality. The menu navigation and various screens are explained in detail later in this section. Backlight:
An automatic backlight is built-in to the LCD for better clarity under low-light conditions. This backlight is enabled on power-up and will automatically turn off if there is no button activity by the user. The backlight will automatically turn on as soon as any button is pressed. Contrast Adjustment:
Internal adjustment on board (in back of front panel button PCB). 3.2.2 Cursor and Screen Control Buttons The buttons on theDATA-20 front panel are used for LCD screen interface and control functions:
<ENTER>
<ESC>
<UP>,<DOWN>
Used to accept an entry (such as a value, a condition, or a menu choice). Used to back up a level in the menu structure without saving any current changes. Used in most cases to move between the menu items. If there is another menu in the sequence when the bottom of a menu is reached, the display will automatically scroll to that menu.
<LEFT>,<RIGHT> Used to select between conditions (such as ON/OFF, ENABLED/DISABLED, LOW/HIGH, etc.) as well as to increase or decrease numerical values.

TX Transmitter Green indicates the transmitter is radiating, and the RF output (forward power) is above the factory-set threshold. 3.2.4 Screen Menu Tree Structure Figures 3-2a, b and c, located on pages 3-7, 3-8, 3-9 and 3-10, show the tree structure of the screen menu system. The figures group the screens into functional sets. There may be minor differences in the purchased unit, due to software enhancements and revisions. The current software revision may be noted in the SYSTEM sub-menu (under INFO). In general, <ENTER> will take you to the next screen from a menu choice, <UP> or <DOWN> will scroll through screens within a menu choice, and <ESC> will take you back up one menu level. Certain configuration screens have exceptions to this rule, and are noted later in this section. CAUTION DO NOT change any settings in the CONFIGURE or CALIBRATE screens. The security lock-out features of the software may not be fully implemented, and changing a setting will most likely render the system non-operational!

DataNex EMS Wireless, DATA-20 Digital Radio Front Panel Operation 3-26 3.4.19.1 Typical Configuration A typical installation of DATA-20 Digital Radios involves configuring each DATA-20 as either Data Communications Equipment (DCE) or as Data Terminal Equipment (DCE), as illustrated below:
Tx Clock Rx Clock Telecom Equipment Configured as DTE Configured as DCE Configured as DTE Repeater
(DCE coupled with a DTE) Configured as DCE A DCE coupled together with a DTE enables the signal to be relayed to another DCE. This configuration is called a Repeater. A network can consist of as many Repeaters as necessary. The following sub-sections describe how to configure the DATA-20 a DCE or as a DTE. 3.4.19.2 DATA-20 as Data Communications Equipment (DCE) By default, the DATA-20 is configured as Data Communications Equipment (DCE). In the mode, the device recovers the transmitted clocks and effectively performs as a modem. DataNex EMS Wireless, DATA-20 Digital Radio 3-27 Front Panel Operation To configure the DATA-20 as a DCE, select the following clock settings in the System menu:
