IR/Serial Port: Connections and Wiring
You can connect up to
eight
IR- or Serial-controllable devices to the IR/Serial connectors on the rear of the NI-
4100 and NI-3100 and up to
four
on the NI-2100 (FIG. 15).
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.
These units come with two CC-NIRC IR Emitters (
FG10-000-11
).
The IR/Serial connector wiring specifications are listed in the following table.

The maximum baud rate for ports using DATA mode is 19200. Also, DATA mode
works best when using a short cable length (< 10 feet).
