In the above table, pin 1 is located on the right side of the port, and the pinouts count up to the left.
IR/SERIAL Port: Connections and Wiring
The IR/SERIAL ports provide IR transmit/one-way serial connections that support high-frequency carriers up to 1.142
MHz. You can simultaneously generate up to eight IR/Serial data signals on the NX-4200 and NX-3200, up to four on
the NX-2200, and up to two on the NX-1200.
These ports 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 to these ports.
NX-3200 and 4200 units each ship with two CC-NIRC IR Emitters (FG10-000-11). NX-1200 and 2200 units ship with
one emitter each.
FIG. 25 displays the IR/SERIAL ports for each NX-series controller.

Note:
The maximum baud rate for ports using DATA mode is 19200. Also, DATA mode works best when using a short
cable length (< 10 feet).
Note:
For each data signal, the negative (-) terminal is for Signal GND, and the positive (+) terminal is for IR/Serial
data.
