1-14 Technical Information
The IR port permits transfer of files to or from portable devices such as laptops and
personal digital assistant (PDA) products using Puma TranXit applications software (not
pre-installed) or other software supporting IrDA data transfer. The port supports data
transfers at 115 Kbps from a distance of 1 meter (3 feet 3 inches).
The IR port uses the system’s COM2 serial port to transfer data. The port shares registers
and function logic with COM2.
