IR/Serial Port: Connections and Wiring
Up to eight IR- or Serial-controllable devices may be connected to the IR/Serial connectors on the rear
of the NI-3101 (FIG. 10). These 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. A data 0 - 5
VDC device may also be connected. These units come with two CC-NIRC IR Emitters (FG10-000-11).
The IR/Serial connector wiring specifications are listed in the following table:
