The Pro-C controller is supplied with a base 4-station module. The Pro-C is also compatible with the EZ Decoder System (EZDS) for hybrid conventional and two-wire operations. Add a Pro-C Decoder Module (PC-DM) to enable control for up to 32 total stations. This system uses the same EZ-1 decoders used with ICC2 and HCC controllers.
The PC-DM can only be installed in the last two station output slots (similar to PCM-900 and PCM-1600 installation). The PC-DM will not physically fit or operate in any other station output slot.
IMPORTANT: While the addition of this module increases total station count to 32, the first 4 stations cannot be programmed as decoders and must be wired conventionally to the 4-station master module. This leaves stations 5–32 available for EZ decoder operation. This allows for hybrid conventional/decoder operation. If only EZ decoders are to be used, there are 28 total stations available, and the first station must be programmed as station 5.
As shown below, if stations 1–4 are conventionally wired, then stations 5–32 would be available for two-wire via PC-DM. Similarly, a 3-station PCM-300 expansion module could be added to the second station output slot, which would allow for stations 1–7 to be conventionally wired, and stations 8–32 available for two-wire.
