IR/Serial Connections and Wiring

You can connect up to eight IR- or serial-controllable devices to the IR/Serial connectors (ports

8-15). These connectors accept an IR emitter (CC-NIRC) that mounts on the device's IR window, or a mini- plug (CC-NSER) that connects to the device's control jack. The IR/Serial connector wiring specifications are listed in the following table.

IR/Serial Connector Wiring Specifications

No.	Port	Signal	Function
1	8	GND (-)	Signal GND
		Signal 1 (+)	IR/Serial data
2	9	GND (-)	Signal GND
		Signal 2 (+)	IR/Serial data
3	10	GND (-)	Signal GND
		Signal 3 (+)	IR/Serial data
4	11	GND (-)	Signal GND
		Signal 4 (+)	IR/Serial data
5	12	GND (-)	Signal GND
		Signal 5 (+)	IR/Serial data
6	13	GND (-)	Signal GND
		Signal 6 (+)	IR/Serial data
7	14	GND (-)	Signal GND
		Signal 7 (+)	IR/Serial data
8	15	GND (-)	Signal GND
		Signal 8 (+)	IR/Serial data

Input/Output (I/O) Connections and Wiring

The I/O port responds to switch closures or voltage level (high/low) changes, or can be used for logic-level outputs.

You can connect up to eight devices to the I/O connectors (port 16). A contact closure between GND and an I/ O port is detected as a Push. When used for voltage inputs, the I/O port detects a low (0-1.5 VDC) as a Push, and a high (3.5-5 VDC) signal as a Release. When used for outputs, the I/O port acts as a switch to GND and is rated at 200 mA @ 12 VDC.

The PWR pin (+12VDC @ 200 mA) is designed as a power output for the PCS2 or VSS2 (or equivalent). The GND connector is a common ground and is shared by all I/O ports. The following table lists the wiring specifications for the I/O connectors.
