RELAYS
You can connect up to two independent external relay devices to the Relay connectors on the device. Connectors labeled
A are for Common and B are for Output (FIG. 15).

Each relay is isolated and normally open.

I/O
The I/O port (FIG. 16) responds to switch closures and voltage level (high/low) changes, or can be used for logic-level
outputs. The PWR pin pr12 VDC @ 200 mA and is designed as a power output for the PCS Power Current
Sensors, VSS2 Video Sync Sensors (or equivalent). The GND connector is a common ground and is shared by all I/O
ports. A common ground is shared with I/O ports 1 - 2.
Inputs are contact closure sensing. Input voltage is as follows:

HIGH (no contact closure): V
IH
> 2.5 V
DC

LOW (contact closure): V
IL
< 0.8 V
DC
Output voltage is as follows:

V
OH
= +3.3 V
DC
+/- 0.3 V

IR
You can connect up to two IR-controllable devices to the IR connectors (FIG. 17).
The IR connectors support generating carriers up to 1.142 MHz. The IR connectors accept an IR Emitter (CC-NIRC)
that mounts onto the device's IR window, or a mini-plug (CC-NSER) that connects to the device's control jack.
You can also connect a data (0 - 5 V
DC
) device.
