be verified in the “Help” tab of RxControl in the “Receiver Identification”
menu. It can also be checked using SurvCE and FIELDGenius.
5.18. Question: My receiver will not respond to commands, why not?
Answer: A setting in the APS-3 may have been incorrectly set causing a
disruption in communication. Power the unit off, remove all power sources,
turn the unit back on. After the unit boots, perform a hard reset and upload
the default script.
If you are using a USB-Serial adapter, the adapter may not be compatible
with the APS-3. If possible connect directly to a physical COM port on the PC.
Otherwise, adapters using prolific drivers have been found to work more
reliably.
5.19. Question: How can I tell which APS-3 model I have?
Answer: The APS-3 model is determined by the APS-3 Serial number found on
the bottom of the unit. Serial numbers in the 10000 series are classified as
APS-3. Serial numbers in the 20000 series are classified as APS-3 V2.
5.20. Question: I cannot connect using the GSM modem, why not?
Answer: Be sure that you are selecting the APS-3 model in your data
collection software. Selecting the wrong model version will cause
communication issues with the GSM modem.
The APS-3 V2 GSM modem requires that Flow Control be enabled on the
system. If this was previously turned off it will need to be re-set. You can
accomplish this by re-uploading the default script to the receiver or by
sending the command SCS,COM2, , , , RTS|CTS using data collection software
or RxControl.
