Appendix K: Flip Cable
Connections
Connector plugs are supplied to help reduce the
use of terminal boxes. To connect the plugs to the
user supplied 0.326mm
2
(22AWG) cabling, refer to
the table below. For how to connect wires, see
instructions supplied with the plugs.
Note: The maximum RS-232 cable distance
possible depends on the data rate, environment
electrical noise, and the inherent cable
capacitance. Using low capacitance 0.326mm
2
(22AWG) or larger cable in a typical installation,
300m (1000ft) have been used at a 1200BPS data
rate, and 15m (50ft) at a 9600BPS data rate and
above.
