Page 2 Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems CHAPTER 2 SRP-VRT OVERVIEW Chapter Two Chapter Two Chapter Two Chapter Two Short Range Programmer-VRT Overview SRP and Components The TRACE Short Range Programmer-VRT (SRP-VRT) is a low power, short range programmer/interrogator activated by a single button for ease of use in the field. Designed for initial transponder programming, the SRPs maximum range is limited so that it can only communicate with the nearest transponder. The SRP is a one-piece handheld unit containing rechargeable batteries. An internal antenna located near the top of the unit provides both transmit and receive communications. An external power supply allows the user to recharge the internal batteries. The SRP is shipped with the following components:

SRP handheld unit External power supply with cable and connector 4 line by 20 character LCD display 17 button keypad 2 INTERROGATE buttons Internal antenna for transmit and receive VRT Label indicating SRP is VRT-

compatible 6 volt charging power supply Charging jack SRP Handheld Unit. The handheld SRP unit has a four-line by 20-

character LCD display and an 18-button keypad, which includes five function keys and two Interrogate (INT) keys. The charging jack is located on the right-hand side of the unit. Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems Page 3 SRP-VRT OVERVIEW CHAPTER 2 How the SRP Works Range. The SRPs range extends outward to approximately twelve (12) inches from the top of the handheld unit. Actual communication range may vary dependent upon environmental conditions. Battery Life. The internal battery allows approximately 24 hours of normal operation on a single charge. Recharging takes about 2 hours. The SRP is both an interrogator (can talk to and receive information from transponders) and a programmer (can program transponders). It sends out a radio frequency (RF) signal embedded with special authorization codes that the transponder recognizes, and thus establishes communications with the transponder for performing various functions. It is designed to operate at short range (within about 12 inches of the transponder) for programming transponders with the current meter index value (and other parameters) at the time of installation. This range limitation helps ensure the SRP programs only the intended transponder and reads back that same transponders status to verify its programming. The SRP has functions built into its internal programming (firmware) that allow the user to determine precisely which transponder is being read and/or programmed. It also allows the user to search for a specific transponder by serial number if there are a number of transponders in the area. With the SRP, the user can also determine and reset the tamper status of transponders, read meter index data and synchronize transponder time with SRP time. Specifications The following table shows the SRP specifications:

Its limited range (about 12 inches)along with its ability to locate individual transponders by serial numberensure the SRP programs only the intended transponder. Verification of the new data is a snap with one touch of a button. Keypad Buttons and Functions The SRP keypad has 16 small buttons and two identical INT

(interrogate) buttons at the bottom. The five tan buttons represent user-

accessible SRP functions. The yellow number buttons allow you to enter numerical data manually. ON/OFF. Alternately turns the SRP on and off. The SRP automatically shuts off after 2 minutes of non-use to conserve battery power. 2 5 8 0 3 6 9 1 4 7 LAST SN WC INT INT LIGHT ENTER MODE Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems Page 5 SRP OPERATION CHAPTER 3 SRP Modes BACK SPACE. Moves the cursor (dark flashing box) back one position to allow the user to change the character displayed in the cursors position. LIGHT. Alternately turns the display backlight on and off. Backlight uses battery power and should be turned off when not needed. MODE. Cycles through all SRP functional modes, advancing one mode per press of the button. LAST SN/WC. Toggles between the last successfully interrogated serial number (LAST SN) and wild card (WC). ENTER. Moves the cursor from one input field to the next on the displayed screen. INTERROGATE. Searches for and initiates communication with the selected transponder (if a serial number was entered) or the nearest transponder (if Wild Card is used). This button is also used to program the baseline meter reading, correction factor (V9 and VRT) and a variety of other features (VRT) into transponders. The SRP has eight functional modes for a variety of operations. 1. Clock 24 Hour Format Mode. Allows the user to set the current time and date into the SRP. When interrogating any transponder the SRP may also broadcast its current time. If the SRP is in Broadcast Mode, all VRT transponders within range of the interrogation will reset their internal clocks to match the SRP time. 2. FIND SN/VERS/TYPE Mode. Allows you to read and display the transponders serial number, type and firmware version. You can interrogate transponders either by using the Wild Card option (to search for any nearby transponders) or by entering a specific transponder serial number. Once the SRP has read the desired transponder, you are ready to perform other functions and switch to other modes as required. NOTE: Find is the only mode in which interrogation acquires transponder firmware version and type information needed for other operations. Page 6 Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems CHAPTER 3 SRP OPERATION Power On/Off 3. READ METER INDEX Mode. Reads the transponders electronic index (e-index). From this mode, you can also press INT (interrogate) to read the transponders serial number and any tamper flags set during or since installation. 4. READ PRE-DIVIDER and CF Mode. Reads the sub-count, pre-

divider and compensation factor (V9 and VRT) recorded in the transponder. 5. Read History / TOU Mode (VRT). Reserved for factory use only. Reads and programs the transponder time-of-use accumulators and history. Also reads the transponder current date and time. 6. Set Meter Parameters Mode (VRT). Reserved for factory use only. Programs the transponders date, time and pre-divider. 7. PROGRAM METER INDEX Mode. Programs the meter index value into the transponder. This mode can also be used to program the compensation factor into the transponder (V9 and VRT). 8. Transponder TX Test Mode. Reserved for factory use only. This diagnostic mode is used by the manufacturer to gauge the performance of a transponders transmitter. The SRP is powered by rechargeable batteries providing about 24 hours of normal operation between recharges. Turning the SRP ON Press the ON/OFF button once to turn the SRP on. Power-on Screen. Each time it is turned on, the SRP conducts a self-test. The screen displays the SRP firmware version, current battery voltage, and one of two messages, either Battery Voltage:

X.XX (where X.XX is voltage) or RECHARGE BATTERY. AMCo, Automated Systems, SRP V01.04.00 10-22-02 Battery Voltage: 2.55 If RECHARGE BATTERY appears, you need to recharge the batteries (indicating a voltage of 1.99 or less). If this message appears with known fully charged batteries, contact AMCO Automated Systems. Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems Page 7 SRP OPERATION CHAPTER 3 Turning the SRP OFF Manual Power-off. Pressing the ON/OFF button at any time during operation will power off the SRP. The last transponder serial number successfully interrogated will be saved. Automatic Power-off. After 2 minutes of non-use, the SRP will automatically power off to conserve the battery. Setting Time and Date and Broadcast Mode The user can set the current time and date in the SRP and also in the VRT Transponders by using the optional Broadcast Time feature. In this mode the SRP will broadcast its current time during each interrogation and VRT transponders will reset their time according to the broadcast. For these reasons, it is important that the SRP time be accurate when VRT transponders will be within range of any SRP interrogation. The Broadcast Time feature is always reset to Off when the SRP is turned off, but may be turned on as described in the following steps. Accessing Time and Date Set Mode 1. Press the MODE button until the SRP Time and Date Set mode

(Clock-24 Hour Format) displays. Clock-24 Hour Format Date: 10-04-02 Time: 08:30:24 Broadcast Time OFF 2. Verify the date and time are correct. To Change Date or Time 1. Press the LAST SN/WC button. 2. Press the ENTER button to skip correct values and move to value(s) you wish to change.

(Date) Enter the correct date using the SRP keypad and press ENTER.

(Time) Enter the correct time using the SRP keypad and press ENTER 3. 4. Page 8 Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems CHAPTER 3 SRP OPERATION To Turn Broadcast Time ON and OFF 1. To Turn Broadcast Time ON: Press ENTER while in the Clock-24 Hour Format screen. If the time and date settings are already correct, you can simply press ENTER to turn Broadcast Time ON. If you wish to change time or date settings, do so, then press ENTER to record the changes and switch Broadcast Time to ON. The SRP will now transmit its current time at each transponder interrogation. NOTE: Broadcast Time will default to the Off setting when you turn off the SRP. However, your latest time and date settings will be preserved in SRP memory. 2. To turn Broadcast Time OFF: Switch the SRP off and back on again. Broadcast Time is always reset to OFF when the SRP is powered off. Your latest time and date settings are preserved, even when the SRP is turned off. In order to program a transponder you must first locate it and interrogate

(read) it to verify that it is the one you want and to determine its characteristics. This is referred to as finding the transponder. The Find mode identifies the transponders firmware version, which, in turn, tells the SRP which modes can be used with that transponder. Using Find Mode To Find a Transponder 1. Press the MODE button repeatedly until the display shows the Find Serial Number screen:

FIND SN/VERS/TYPE Serial No.. ????????

If no serial number is currently displayed and you want to find a specific transponder:

2. Enter the serial number of the transponder you want...

If a serial number is currently displayed and you want to find all transponders within range:

3. Press the LAST SN/WC button to change the display to Wild Card

(all question marks). This will list all transponders within range of the SRP. To Interrogate a Transponder 1. Hold the SRP close to the transponder and press either of the two INT (interrogate) buttons. FIND SN/VERS/TYPE Serial No.. ????????

INTERROGATING If the interrogation is successful, the screen will display the transponder serial number, meter type and transponder firmware version:

FIND SN/VERS/TYPE Serial No.. 03571641 TYPE=GAS VERS=09 If the interrogation is NOT successful, the screen will display the CARRIER NOT DETECTED message (indicating no signal from transponder) or RECEIVE DATA ERROR (indicating radio signal interference). This message displays for 2 seconds

(during which time the SRP will not interrogate), then returns to the initial mode screen. If the interrogation is NOT successful, move the SRP to a slightly different position relative to the transponder (closer, farther away or to one side) and interrogate again. Radio waves can bounce off of, or be absorbed or deflected by, various materials (especially metals) which can create differences in signal strength from one spot to another. 2. Page 10 Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems CHAPTER 3 SRP OPERATION Using Read Meter Index Mode This mode reads the meter index (meter count). It will display whole units only. (For pre-divider/sub-count values use Read Pre-divider mode.) 1. Press the MODE button repeatedly until the display shows the Enter Read Meter Index screen. READ METER INDEX Serial No..

2. Acquire the transponder serial number. Acquire serial number either: (a) by using the Find mode first or

(b) by manually entering the serial number in this mode. Press one of the two INT (interrogate) buttons. If the interrogation is successful, the SRP will display the transponder serial number, the current meter index value and the tamper indicator, if applicable (as shown below):

READ METER INDEX Serial No..

INDEX NO.. 00001234 TAMPER Any TAMPER indication that appears will not appear again on the next interrogation. (Tampers are automatically cleared after interrogation.) If the interrogation is NOT successful, the screen will display the CARRIER NOT DETECTED message (indicating no signal from transponder) or RECEIVE DATA ERROR (indicating radio signal interference). These messages display for 2 seconds, during which time the SRP will not interrogate.. If the interrogation is NOT successful, move the SRP to a slightly different position relative to the transponder (closer, farther away, or to one side) and interrogate again. Radio waves can bounce off of, or be absorbed or deflected by, various materials (especially metals) which can create slight differences in signal strength from one spot to another. 3. 4. Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems Page 11 SRP OPERATION CHAPTER 3 Using Read Pre-divider (and CF) Mode This mode reads the current sub-counts and pre-divider along with the current compensation factor (V9 and VRT). NOTE: The CF displays with the pre-divider only if the transponder firmware supports CF and this can only be determined if the transponder is interrogated first in the Find mode. 1. Press the MODE button repeatedly until the display shows either of the two Read Pre-divider screens below:

For transponders accessed directly through Pre-divider mode:

READ PRE-DIV and CF Serial No.. 03571641 For V9 and VRT transponders interrogated in Find mode:

READ PRE-DIVIDER Serial No.. 03571641 If the serial number represents the target transponder, go to step 4. 2. 3. If Find mode was not used, or the displayed serial number is not the serial number of the target transponder, enter the serial number of the desired transponder. 4. Press either of the two INT (interrogate) buttons to read the pre-

divider (and CF if applicable). If interrogation is successful, the screen will display the serial number and pre-divider (and CF if applicable) as shown in the examples below:

READ PRE-DIVIDER Serial No.. 03571641 PRE-DIV... = 001/100 Page 12 Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems CHAPTER 3 SRP OPERATION 5. For V9 and VRT transponders which were interrogated in Find mode, the compensation factor also displays on the lower line:

READ PRE-DIV and CF 03571641 Serial No.. PRE-DIV... 001/100 COMP FACT.= 200/250 If the interrogation is NOT successful, the screen will display the CARRIER NOT DETECTED message (indicating no signal from transponder) or RECEIVE DATA ERROR (indicating radio signal interference). This message displays for 2 seconds, during which time the SRP will not interrogate. If the interrogation is NOT successful, move the SRP to a slightly different position relative to the transponder (closer, farther away, or to one side) and interrogate again. Radio waves can bounce off of, or be absorbed or deflected by, various materials (especially metals) which can create slight differences in signal strength from one spot to another. Using Program Index (and CF) Mode This mode programs the current meter index value and compensation factor (V9 and VRT). NOTE: The compensation factor may be programmed only if the transponder firmware supports CF and this can only be determined if the transponder was interrogated first in the Find mode. 1. Press the MODE button repeatedly until the display shows either of the following two Program Index (and CF) screens:

For transponders accessed directly in Program Index (and CF) mode:

Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems Page 15 SRP OPERATION CHAPTER 3 Charging Batteries The SRP batteries typically deliver between 2.0 volts and (when fully charged) 2.6 volts If the voltage drops near 2.0 (as shown on the power-

on screen), you should recharge the batteries. Battery charger. A 6 volt external power supply allows you to recharge the internal batteries by connecting the SRP to the charger and plugging the charger into a standard 120 VAC outlet. The SRP can be operated while it is charging if needed to troubleshoot transponders in the shop. CAUTION: When the battery is completely dead, it may take up to 15 minutes on charge before the unit will resume operation. Battery charger. Plug into 120 VAC wall outlet Connect charger jack to port on SRP Page 16 Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems CHAPTER 4 TROUBLESHOOTING Chapter Four Chapter Four Chapter Four Chapter Four Troubleshooting The following table offers troubleshooting tips for some common SRP conditions. For all other matters, contact AMCO Automated Systems. Symptom Possible Cause Solution Upon start-up, SRP displays RECHARGE BATTERY message. Upon interrogation, SRP displays the CARRIER NOT DETECTED message and does not display transponder data. Battery voltage too low. Recharge batteries. The SRP is out of range of the transponder. Move the SRP (and particularly the top, where antenna resides) closer to the transponder. The SRP is receiving outside interference. Manually entered transponder serial number is not valid. Transponder is not responding to interrogation signal. First History/TOU or Set Meter Parameters program command interrogation (VRT). Move the SRP (and particularly the top, where antenna resides) closer to the transponder. If other TRACE readers or programmers are operating nearby, wait until they have moved away and try again. Wait 2 seconds, re-enter the desired serial number and interrogate again. If interrogation fails again, check source of serial number and verify/correct number. Move the SRP (and particularly the top, where antenna resides) closer to the transponder. If other TRACE readers or programmers are operating nearby, wait until they have moved away and try again. Interrogate for the second time. Second or subsequent History/TOU or Set Meter Parameters program command interrogation attempted beyond 1 minute timeout (VRT). Restart command sequence by re-entering transponder serial number in SN-ADR/CMD field and interrogating. Repeat command interrogation. Upon interrogation, SRP displays READ DATA ERROR. The SRP is receiving outside interference. Two or more transponders are within in range of the SRP simultaneously. Move the SRP (and particularly the top, where antenna resides) closer to the transponder. If other TRACE readers or programmers are operating nearby, wait until they have moved away and try again. Set the SRP (and particularly the top, where antenna resides) directly on the desired transponder. Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems Page 17 TROUBLESHOOTING CHAPTER 4 Symptom Possible Cause Solution These operations do not allow the Wild Card option. Enter serial number manually or obtain serial number via Find mode. This occurs normally at first interrogation after a transponder has been powered up (either new or reset). This occurs normally after the second interrogation of a new or reset transponder and will remain until transponder is programmed. Interrogate again to clear messages. Program transponder. Upon attempting to read or program index or pre-divider, SRP displays Wild Card Not Valid message. Upon interrogation, SRP displays CS/LOAD ERR and TAMPER messages. Upon interrogation, SRP displays CKSUM ER message. Page 18 Short Range Programmer VRTUser Guide P/N 52806T100 Rev 1 April 2003 AMCO Automated Systems
