B-5
crimpers ($15). Get someone familiar with making network (Ethernet)
cables, but be sure to tell them not to use the Ethernet pin outs for the Relay
Stations, (it has been tried more than once!).
Testing the Relay
To test communication with a Relay, first check out the radio by doing a
Site Test on the offending Relay with all other Relays and Bases OFF. To
check if a Relay is working with a Base Station, set the Base to a different
frequency than the Relay and set the Terminal frequency to match the Relay
frequency. Be sure to set RELAY=YES on the Terminal Setup. Then cable
-connect the Relay to the Base (RELAY port to RELAY port.
Start your application on the host or use one of our demo programs
provided with the Terminal (it’s a good way to test) - it takes 10 or more
seconds for the Terminal to switch to the Relay. The delay is a result of the
Terminal having to put out a "who can hear me" message when it doesn't
get a response from the Base Station. The Relay responds to the Terminals
"who can hear me" message and communication is established through the
Relay. You will notice slightly slower throughput when working through
the Relay.
Relay ID and Frequency…
Relays should be set to the same frequency as the Base station and R/F
Terminals that you will be using in your system. Determining the current
frequency is the same as on the Base station; power up the Relay and count
the number of times the LED flashes (frequency + 3). The default setting is
Frequency 0 (3 flashes). Each Relay also requires a unique Relay ID; the
default ID is 0.
To change the Relay ID or frequency, you must open the Relay case.
