Serial Ports
The NX-series controllers each feature device control serial ports that support either RS-232 or RS-232, RS-422, and
RS-485 communication protocols. Each port supports the following specifications:
XON/XOFF (transmit on/transmit off)
CTS/RTS (clear to send/ready to send)
300-115,200 baud rate
RS-232 Ports
The RS-232 ports (ports 2-4 and 6-8 on the NX-3200/4200; ports 2-4 on the NX-2200; port 2 on the NX-1200) are 5-pin
3.5 mm mini-Phoenix (male) connectors used for connecting A/V sources and displays. These ports support most
standard RS-232 communication protocols for data transmission.
FIG. 21 displays the RS-232 ports for the NX-series controllers.
