IR Communication
IR communication can be used to transfer data between two
Handheld Printer Terminals.
When performing IR communication, orient the IR ports of both
Handheld Printer Terminals so they are pointing directly at each
other.
Data communication is possible within a distance of 0 (in direct
contact) to 1 m (max. 20 cm at 4 Mbps).
Important!
• A high-sensitivity communication element is used during IR communication.
• In order to ensure successful communication, avoid using cellular phones or other devices that emit radio
wave in the area where you are performing IR communication.
• If you need to use such a device, move away from the communicating Handheld Printer Terminals. In
case of a cellular phone, keep it at least 30cm (11

Terminal and your computer. With the power turned off, open the
connector cover ( 1 ) and connect the RS-232C interface connector
