In the case of a multiple IMC-300MKII-xx controllers (or alternative CS-Bus controllers), only one
connection to the RS-232C Connector on the master controller (the IMC-300MKII-EM Controllers) is
supported.
3.3 CS-Bus Connections (for connection to keypads and to additional IMC-100MKII-xx controllers) . ( See
Figure 3 above.)
Directions
a. Prepare communication wire with RJ-25 connectors on each end. (An RJ-25 connector is similar to
traditional RJ-11 connector except it has 6P6C). Straight wiring should be used (i.e. 1-2,2-2,3-3,4-
4,5-5,6-6). Pinouts are shown below:
Note: Wiring is incompatible with standard telephone wiring and therefore telephone cabling
should not be used.
