Page 10 Short Range Programmer VRT—User Guide
P/N 52806T100 Rev 1 April 2003 • AMCO Automated Systems
Press the LAST SN/WC button to display the serial number of the
last transponder successfully “found.”
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.
• If the interrogation is successful
, the screen will display the
transponder serial number, meter type and transponder firmware
version:
• 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.
2. 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.
