Wiring and Connections
The following table list the wiring specifications for the I/O ports. In this 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.
The IR/Serial connector wiring specifications are listed in the following table.
