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.
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.
