RS-232 - Termination Box
A termination box can be purchased from Gasboy. Gasboy provides the installer with an easy-
to-wire terminal block connected to the proper pins on an RS-232D female connector. The
terminal block will accept up to 18 AWG wire.
RS-422 - SHMs
A Gasboy SHM and the appropriate interconnect cable must be used when the RS-422
communication mode is being used to communicate to the ports of the TopKAT system. It
must be used for distances between 100 and 1500 feet (31 and 455 meters). It can be used for
distances under 100 feet in place of RS-232 wiring. One SHM is required at the remote end of
the communication wiring. Refer to
“Port Communication Wiring” on page 28 for wiring
diagrams.
