3.4 Infrared Communications Mode( IrDA Only) : 

ƒ

 

Dip Switch #1 and # 2( Disable UART 0)  must be in the <ON> position. 

ƒ

 

The printer can be powered up by pressing the power <On/Off> switch 

ƒ

 

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” up 

and print the requested data  

ƒ

 

If Dip Switch # 1 and # 2 only are ON then the baud rate of the IrDA 

communication is set at 9600 bps. If you wish to default to variable IrDA 

    ( 9600- 38400) then you should also turn Dip Switch  # 4 ON. 

ƒ

 

Pressing the power switch again will turn the printer <OFF>. 

3.5 Bluetooth/802.11b Communications Only : 

ƒ

 

Dip Switch #1 must be in the <OFF> position 

ƒ

 

Dip Switch # 3  and # 2 must be in the <ON> position  

 

Note:Since UART 1 (RS232) and UART 2 (IrDA/BT/802.11b)  share the 
same Dip Switches, the same baud rate , parity and stop bits settings 
apply both for RS 232 and BlueTooth/802.11 (Refer to Developer’s 

Manual for further details) 

 

Note: Adjust settings to match those of the BT or 802.11b module in your 
computing device 

ƒ

 

The printer can be powered up by pressing the power <On/Off> switch 

ƒ

 

Depending on Whether you have an 802.11b or a BLuetooth Module installed 

the printer will enter that state respectively. 

ƒ

 

Pressing the power <On/Off> switch again will turn the printer <OFF>. 

 

Note :It is necessary for the mobile computing device you are using to 
discover the printer. Refer to the instructions provided by the systems 
integrator. 

 

Note: Systems Integrators: Refer to the Bluetooth manual provided with 
your mobile computer and the Bluetooth section of the Developer’s 

Manual /802.11b Application Note available for this printer. 

3.6 Using the Magnetic Stripe Reader: 

ƒ

 

The Magnetic Card Reader is a factory-installed option. This option requires 

special application software to read and process cards with a magnetic stripe, 
such as credit cards or driver’s license 

 

Note: Refer to the Figure 4 if your printer is equipped with the optional 
magnetic stripe reader 

ƒ

 

Quickly swipe the card through the reader either left to right or right to left. 

The magnetic stripe must be facing toward the paper supply door as 
indicated below while it is passed through the reader 

ƒ

 

Refer to Table 4 for the description of the LED indicator Status.
