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.
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 another MX5'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 "MX5 Reference Guide" for complete instructions.
The Keypad
The keymaps (keypress sequences) are located in “Appendix A - Key Maps.”
Scan Key Function
When programmed as Scan keys, either the left or right Scan key activates the
scanner. The internal scanner scans only when the Scan button is pressed (or
when the scan trigger is pressed on the optional trigger handle, if installed).
Enter Key Function
The Enter key is used to confirm a forms entry or to transmit information. How it
is used is determined by the application running on the computer.
2nd Key Function
The Orange ( on the upper left side of the keypad ) and Blue ( on the upper right
side of the keypad ) keys are 2nd keys used to activate the 2 nd functions of the
keypad. Printed above many keys are small characters, in either orange (on the
left side of the key) or blue (on the right side of the key), that represent the 2 nd
function of that key. Using the 2 nd key activates the second key function. Note
that the 2 nd key only stays active for one keystroke. Each time you need to use
the 2 nd function you must press the Orange or Blue 2 nd key. To cancel a 2 nd
function before pressing another key, press the 2 nd key again.
Ctrl Key Function
The Ctrl key enables the control functions of the keypad. This function is similar
to a regular keyboard’s Control key. Note that the Ctrl key only stays active for
