erage. Alternatively, locating the Base Station and Relay as shown below results in better coverage:
To Site Survey a Relay, all other Relays and Base Stations must be turned off. This is the only way to know for sure which Relay is
responding. Alternatively, perform the Relays' test out of range of the other Relays and Base Stations.
Relay Installation
Relay Stations are connected to the Base by twisted-pair wire. See Appendix B: Adding Relays for the pin outs and a testing
plan.
Is radio traffic contention likely?
The radio traffic time is about 30ms per transaction. Radio time is not going to be a gating factor, even with more terminals than the
allowed 64 maximum.
The bottleneck could partially be the serial port baud rate in high volume applications. The default baud rate is 9600 baud; you
can increase this up to 115,200 baud, but the greater the baud rate, the less the RS-232 cable distance allowable.
The gating factor for the application is almost always going to be the application program. By splitting the application between
two or more work stations, each talking to a separate set of Terminals/Base Station, that factor can be minimized.
