4 Setup the Channel Master
Figure 5 through Figure 7, page 11 illustrates how to connect the Channel
Master cable to your computer and power. Make sure the Channel Master
is resting with the vertical beam facing upward or on its housing end to
protect the I/O cable connector and the transducer urethane faces.
Channel Master units are pre-configured to use RS-232, RS-422, or SDI-12
communications protocols. Your computer’s communication port must
match the Channel Master, or use an adapter. To change the communication
protocol, see “Personality Module Replacement,” page 32.

NOTE. If you ordered the RS-422 configuration, the Channel Master is
supplied with a RS-232 to RS-422 converter. The RS-232 to RS-422
converter must be disconnected from the Channel Master when the cable
has been disconnected from the computer. If left connected, the internal
battery used to maintain ROM inside the Channel Master can be drained or
false Breaks may be sent.
