communication status and communication interface.

The Termination switch is used if there are extremely short cables
between the transmitter and the modem.
The Gain switch is set to Lo by default. This setting is sufficient in most
cases. The Hi Gain setting may be used if cable dimensions are
insufficient resulting in a heavily damped communication signal.
7.1.8 Communicating with TankMaster™
TankMaster WinSetup allows you to setup the communication between a
PC, Field Communication Unit (FCU) and field instruments in a
Rosemount Tank Gauging system. For each communication port that is
used on the PC a protocol channel has to be configured (see the
TankMaster WinSetup Reference Manual for more information on
communication protocol setup).
