However, more often than not you will need to clear the status and then conduct a test of each
path to see if it is working.
Here are some general steps to follow when debugging a radio setup.
If you can have a person at site 2 while another is at site 1, try some simple tests shown in
steps 2 to 5. Otherwise skip to test 6.
Key the transmitter at site 1 with the “Turn On radio” option and then verify that carrier is
detected at site 2.
Unkey the transmitter at site 1 with the “Turn off radio” option, and make sure carrier
detect drops at site 2.
Key the transmitter at site 2, verify that carrier is detected at site 1.
Unkey the transmitter at site 2, and make sure carrier detect drops at site 1.
Try sending a test mail message from site 1 to site 2 with the “Send Mail Message” option.
Select a destination (the default of “*” will cause the message to be sent to every unit) and a
message to send. Start with a short simple message, and then lengthen it to stress the radio.
You will receive either the message "Mail Delivered." if an acknowledgment was received or
"Operation Failed." if an acknowledgment was not received.
Try the same test at site 2 if possible.
If you cannot get steps 1 through 7 to function reliably then the rest of your radio system
will not work.
You may also debug communications problems using the 8310’s command prompt. The main
advantage here is you can monitor communications with the built-in SSP decoder. Issuing the
command “report ssp” from the 8310’s command prompt will allow you to see SSP messages
being received or sent on any of the 8310’s communications ports. To watch a particular port
you can specify the port number (ex: “report ssp2” would monitor SSP traffic on COM2:). To
monitor SSP traffic over TCP/IP, issue the command “report ssp0”. The decoder can help identify
problems in the setup. When working from the command prompt, the “status” command is very
handy for observing message counts, and the “mail” command can be used to send or check for
test messages. In general, the master station sends an SSP opcode, and the receiving station
responds with either a response opcode or an acknowledgement. Each message also has a “to”
and “from” address. If the “to” address doesn’t match the unit receiving the message, it will
neither process nor acknowledge the message. For instance, when an 8310 sends an alarm
message, it will send a message with the opcode OpAlarm, and expect back an OpAck of the
OpAlarm. In a functioning system you will see both messages using the SSP decoder.
The PASSTHRU command may also be used to take over control of a serial port and send
characters to the attached device. Depending on the device, this can be used to help verify
proper wiring, power, and operation.
