9.3. Unlicensed Serial Radio - Specific Troubleshooting
My Master radio is receiving odd or incorrect data after a poll request.
Several scenarios can cause radios in the network to send odd or incorrect data back
to the Master radio.
FGR2 radios running firmware versions prior to 8.74 have a known issue in RS485
mode that echoes data back to the Master radio.
1. In Tool Suite, save a network diagnostic file for the network.
2. Review the file to find any radios that are running firmware versions older than
8.74.
3. Upgrade those radios to the latest version of firmware available.
Note: For more information, see Upgrade the Radios to the Latest Software Version (on
page 30).
There is a serial interface mismatch between the site, the device, or the radio.
1. In Tool Suite, save a network diagnostic file for the network.
2. Scan the file for serial radios with a Serial Interface parameter set to RS232.
3. For RS232 radios, look at the Data TX information in the summary view for any
radio that has an excessively high Data TX.
4. Search for one or more sites that increase the data count by the number of bytes
contained in the poll request.
Example: If a poll is 64 bytes, the data poll increases by 64 bytes after the poll.
5. The identified sites may be configured as RS232, but wired as RS485.
Send a technician to the site to verify the wiring.
6. If the site is wired for RS485 and the device connected to the radio is an RS485
device, correct these parameter settings on the Baud Rate tab.
Send these new settings to the radio:
Parameter New Setting
Serial Interface RS485
Setup Port Diagnostics Only
Modbus RTU 1
Turn Off Delay 4
7. If the site is wired for RS485 and device connected requires RS232, correct the
wiring from the radio to the device.
