3.3.8 Connections to a Bristol Model 3808 Transmitter

You can connect a Bristol 3808 transmitter (digital) to the ControlWave

ExpressPAC through either an RS-232 or RS-485 port. Communication

schemes and cable lengths determine the type of communication port

you need to use. In general RS-232 communications require that you

place the 3808 transmitter within 25 feet of the ControlWave

ExpressPAC (local communications). You can use RS-485

communications to reach transmitters up to 4000 feet away (remote

communications).

Figure 3-6 details RS-232 wiring connections required between the

ControlWave ExpressPAC and the 3808 transmitter.
