2.6.4 Printer/PC
A serial printer or a PC (personal computer) may be connected to TB7 Terminals 1 - 4 on
the FACP. The printer can be used to provide a hard-copy printout of real-time events,
history file and walktest data. An IBM compatible PC can be connected to provide local
FACP programming capabilities using the PK-9600 programming utility. Installation of
either device requires panel programming to allow the FACP to communicate with the
device.
CAUTION! Do not connect a printer or PC to the Unimode 9600 FACP if a ground fault
exists on the control panel. Circuit damage may result. Remove all power (AC and DC)
before installing or removing any wiring.
Installation
Remote printers and PCs require separate primary power. Also required is the PRT/
PK-CABLE which is an interface cable prewired to a DB9F connector. Wire the PRT/PK-
CABLE to TB7 Terminals 1 - 4 as illustrated in the following figure. Connect the DB9F
connector to the printer or PC serial EIA-232 port. If a nine-pin serial connector is not
available on the printer or PC, use a DB25 adapter. Make certain that the DB25 adapter
does not swap the Transmit and Receive lines. Apply power to the FACP and printer or
PC. Note that a ground fault may occur on the FACP, dependent on the printer or PC
being used, due to this connection. For this reason, it is important that there be no
preexisting ground fault on the panel.
Note that the printer may or may not be supervised as determined by user programming.
Refer to "Printer/PC" on page 92.
Printer Configuration
Refer to the documentation supplied with the printer for pertinent information about
printer setup. Set the printer’s options as listed in the following table:
