IC693CBL304/305
Port Expansion (WYE) Cables for PCM, ADC, and CMM
Function of cable
A WYE cable (IC693CBL304 for PCM300; IC693CBL305 for PCM301/311, ADC311, CMM311,
AD693CMM301, and SLP300) is supplied with each PCM, ADC, and CMM module. The WYE
cable is used to separate two ports available on a single physical connector; the cable separates the
RS-232 from the RS-485 signals. In addition, the WYE cable allows cables used with the Series
90-70 PCM to be fully compatible with the Series 90-30 PCM. The WYE cable and cable
connections are shown below and on the following page.
Each WYE cable is 1 foot in length and has a right angle male connector on one end that connects
to the PCM module. The other end has a dual female connector with one connector for port 1 and
the other for port 2.
