When using a PC that does not have an installed IR port, a commercially available serial to
infrared adapter is required. Connect the adapter to the PC’s serial port before continuing.
1. If necessary, enable the IrDA protocol driver (IRPLUS.EXE) in the MX3
CONFIG.SYS file.
2. Begin running the communications software on the receiving unit. Set up the
software to receive data.
3. Begin running the communications software on the sending unit. Set up the software
to send data.
4. Face the infrared ports on the two devices toward each other, and place the units
approximately 3 feet apart. Offset the optical centerline of the two devices 15
degrees. 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.
