Figure 2-18 Infrared Port - COM2 Port
At the back of the MX3 Computer there is an Infrared (IR) Data Port. The IR Port is designed to
provide a data link between the MX3 and a similarly equipped piece of equipment such as a
printer. The IR port is the MX3’s COM2 port and is a bi-directional half-duplex communication
port. It supports baud rates up to 115k (although restricted if using IrDA software to 19.2k).
The IR operating envelope has a distance range of 2 cm (.79 inches) to 1 meter (3.2 feet) with a
viewing angle of 30 degrees.
The MX3 uses LXE’s IrDA Lite Plus protocol to send data in both directions, but not
simultaneously. When sending data through the IR port, make sure the IR port on the first MX3
and the IR port on the second MX3 are in close proximity to each other. IrDA is not required and
not used by terminal emulation programs.
See Chapter 5, “Utilities”, for further information about using IrDA Lite Plus.
When the MX3 is docked in a cradle, the Status LED on the cradle is red when data is being
transmitted through the IR port.
