RS-232/422/485 Serial Ports
The UC-7122/7124 computer comes with two embedded serial ports, referred to as “COM1” and
“COM2.” COM1 is hidden inside the embedded computer’s outer casing, and is only used for
debugging purposes when developing the firmware. COM2 is used as a console port, and allows
users to connect to the computer through a 3-pin serial cable. Neither of the two COM ports are
programmable, and for this reason they cannot be used by your applications.
The UC-7122’s 2 serial ports are designated as “COM3” and COM4” (from left to right). The
UC-7124’s 4 serial ports are designated as “COM3” to COM6” (from left to right). The serial
ports are designed to provide reliable, high-speed operation (up to 921600 bps). Each port supports
three operation modes (RS-232, RS-422, and RS-485) to handle a diversity of applications. For
detailed information on configuring the serial ports, please refer to the “Serial Port Configuration”
section in Chapter 3, “Web-based Management.”
