IR/Serial Port: Connections and Wiring
You can connect only one IR- or Serial-controllable device to the IR/Serial connectors on the rear of the
NI-700 (FIG. 8) but you can connect up to three IR- or Serial-controllable devices to the rear of the
NI-900.
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. You can also connect a data 0 - 5 VDC
device. This unit comes with a single CC-NIRC IR Emitter (FG10-000-11).
The IR/Serial connector wiring specifications are listed in the following table.
