2.3.3 POWER-UP VIA DATA INTERFACE
The MSP/MPP printer can be powered-up by transmitting a single character or
activating <RTS> or <SELECT> signals on the interface connector.
To avoid the loss of data during "Logic Switching", the following software features must
be implemented in the Host program.
After sending a wake up character or activating the <RTS> or <SELECT> signals.
- Pause for 1.6 seconds before sending additional characters to the printer.
- Verify the status of <CTS> or <BUSY> before sending additional characters.
- Wait for the XON character from the printer.
The printer turns off power automatically, 30 seconds after the last character received
or de-activation of the <RTS> or <SELECT> signals.
2.3.4 PRINTER BATTERY PACK
The MSP/MPP printer is designed to operate with a 5.0 VDC/ 800 mAH rechargeable
Ni-Cd battery pack. The battery recharge and monitor circuits are located on the printer
controller.
Two LED indicators showing the status of the battery pack are provided.
The <Low BAT> LED is turned on when the battery voltage drops below 4.1
volts.
The <Charge> LED is on while the battery is accepting charge. It turns off
automatically at the end of the charge cycle, when battery voltage reaches 5.56
volts.
8 to 10 hours are required to fully recharge the batteries. Up to 216,000 characters can
be printed with a fully charged battery pack.
The battery pack will hold charge for 800 to 1000 hours after complete recharge.
Remove the battery pack from the printer battery compartment during long storage or
shipping. Additional battery packs and a 4 pack battery charger are available. The part
