Figure 2-13 Infrared Port - COM2 Port
At the back of the MX3-CE Computer there is an Infrared (IR) Data Port. The IR Port is designed
to provide a data link between the MX3-CE and a similarly equipped piece of equipment such as a
printer. The IR port is the MX3-CE’s COM 2 port and is a bi-directional half-duplex
communication port. It supports baud rates up to 115k. It will support serial port emulation, as
well as IrDA and Winsock over IR protocols.
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-CE uses IrDA 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-CE and the IR port on
the second MX3-CE are in close proximity to each other. IrDA is not required and not used by
terminal emulation programs.
When the MX3-CE is docked in a cradle, the Status LED on the cradle is red when data is being
transmitted through the IR port.
