the Serial Interface signals and pin outs for the RJ connector. The connector pin locations
are shown in Figure 11.

 Dip Switch #1 and #2 must be in <OFF> position to activate the serial communication
interface.
3.4 Infrared Communications Mode (IrDA)

Dip Switch #1 must be in the <ON> position.
 The printer can be powered ON by pressing the power <On/Off> switch.
 If no IrDA connection is made, the printer will automatically power down to a lower power
level to conserve battery life. It will remain in a “sleep” mode until an IrDA connection is
made, at which time the printer will “wake” and print the requested data.
 Pressing the power switch again will turn the printer <OFF>.
