USB Port
The serial port/USB port also supports serial data transfer (using a null modem cable) and USB
I/O at 1.5 Mbps. The MX5X automatically detects the cable configuration. Host and client is
automatically configured based on the type of cable used. Refer to section titled Accessories in
this guide for part numbers for the DB26-USB cable and the null modem cable.
IR Port
The InfraRed (IR) port provides a means of transferring information to a device with a similar
port and the proper software. The IR port can be used to communicate with printers or a host
computer with the use of an adapter.
Figure 26 IR Port on MX5
The IR Port is specified as COM 3 and is a bi-directional half-duplex infrared port. It supports the
Slow IrDA (Infrared Data Access) PHY Layer standard that allows communication speeds up to
115k baud.
When sending data through the IR port to a separate device's IR port, make sure both units are in
close proximity to each other. The IR operating envelope has a distance range of 2 cm (.79 inches)
to 15 centimeters (6 inches) with a viewing angle of 30 degrees.
See the MX5X Reference Guide for complete instructions.
