Section 3: Operation
Terminal
A local terminal can be connected directly by an EIA-232
communication cable to the RAC2-8, or a remote terminal can be
connected through modems. All of the status information and control
functions available at the RAC2-8 local display are available from the
terminal. An additional function available at the terminal is Set Modem.
The terminal also displays a status message with time and date stamp
whenever a unit changes status (OFF or ON). These status messages
will be printed if a printer (instead of a terminal) is connected to the
EIA-232 port. Once each 24 hours (at midnight) the terminal checks its
ability to communicate with the RAC2-8 and writes a Comm Check
message.
A terminal connected to an active RAC2-8 displays alarm and status
messages when they occur. The prompt then asks the operator to press
<space>, <S>, or <A>.
