NOTE: In order for changes to the DIP Switch conguration to take effect, the printer’s power must be reset, which happens automatically when the battery is removed to reach the DIP Switch.

Communication

• The MP350 has two serial communication UARTs. It is able to support two modes

of communication simultaneously – either RS232 and IrDA (If DIP switch 1 is on) or RS232 and Bluetooth (If DIP switch 1 is off and DIP switch 2 is on).

• DIP switch 2 is used to control the RS232 port. If the switch is turned on the

RS232 Port is disabled and if it is turned off the RS232 Port is enabled. If RS232

interface is not required, disabling the port will save battery power.

• Bluetooth communication is available if optional daughter boards are installed.

Serial Communication Specication

• The RS232 interface signals for the MP350 printers are terminated on a

6-pin RJ type data connector located on the side of the printer.

• Six connections are provided from the serial interface to the host computer. The

serial interface signals and pin outs on the RJ connector, and the connector pin locations are shown below.

• A minimum of two connections are required for operation: RXD – pin 3 and Common

– pin 1.

NOTE: The communication parameters: baud rate, data bit and parity must be set the same as the host device

settings.

RJ45 Connector Pin # Functional Description Signal Name

3 RS232 from host (Input) RXD

2 RS232 from printer (Output) TXD

6 Request to send from host (Input) RTS

4 Clear to send from printer (Output) CTS

1, 5 Logic common COM

Infrared Communication Mode (IrDA)

• DIP switch 1 must be in the on position.

• The printer can be powered up 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 up” and print the requested data.

Bluetooth Communication (Option)

• DIP switch 1 must be in the off position.

• DIP switch 2 must be in the on position.

• Adjust the settings to match the Bluetooth module in your computing device.

• The printer can be powered up by pressing the power on/off button.

• Pressing the power on/off button 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 Bluetooth manual provided with your mobile computer and the Bluetooth section of the MP350 Developer’s Manual.

Magnetic Stripe Reader (Option)

• The Magnetic Stripe 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 a driver’s license.

• The MP350 Mobile Printer requires an adapter output of 10V DC/1.32A.

• The battery fast-charge is initiated each time the AC adapter output cable is

connected to the printer.

• The fast-charge controller checks the battery’s voltage and temperature before the

start of the fast-recharge process. If the battery voltage or the temperature is outside of the fast-charge limits, the charger defaults to trickle charge at C/10 or 70 mA rate.

• Optional external battery chargers are available for Unitech batteries.

Refer to “Printer Supplies” on page 30.

Important Notes on Replacing Batteries

• Check for the correct Unitech part number for the battery and only order that part for

your new battery.

Caution! Risk of explosion if battery is replaced by an incorrect type.

Dispose of used batteries according to instructions on page 28.

Verifying Battery Charge State

Follow the steps below to identify and correct any battery power problem that may be encountered. These steps will help identify a problem with the printer.

To Test the AC Adapter:

• Use a multimeter and measure the output voltage. Output should be 10V DC.

• Press the on/off button and wait until all LEDs are off.

• Insert the AC adapter output cable into the printer. If the Amber LED goes on, the

battery is not fully charged, but the charge circuit is functioning.

• The AC power portion of the circuit appears ok.

To Test the DC Power:

• Disconnect the AC adapter output cable once the battery has charged for

ve minutes.

• Press and hold the feed button, then press and release the on/off button

and then release the feed button. The printer will print a “self-test” receipt.

• If the self-test receipt is printed, the DC power is ok.

To Test if the Battery is Accepting the Charge:

• Press the on/off button and wait until all LEDs are off.

• Plug the AC adapter output cable into the printer. Press the on/off button;

the green LED will illuminate and after about 20 seconds the LED should turn off.

• If the amber LED is on, the battery is accepting a charge and the charge circuit

is ne. The LED will turn off at the end of a 180-minute charge cycle.

Battery and Safety Information

The printer is powered by a 7.4V Li-Ion 2200mAh battery pack.

• Charging time in the printer is approximately three hours.

• Take the battery out of the printer during long periods of storage.

• The battery storage temperature is 40°F to 104°F (4°C to 40°C). Do not store a

fully charged battery at temperatures greater than 104°F (40°C) for long periods

of time – the battery may permanently lose charge capacity.

• The recommended temperature for charging is between 68°F (20°C) to 77°F (25°C).

• Be sure to use a fully charged battery before long or battery intensive

printing sessions. Certain operations (e.g., printing receipts with a lot of bar codes and graphics) drain the battery more quickly than others.

• Dispose according to your local regulations. Do not throw in trash.

Caution! Do not disassemble, short circuit, heat above 80°C or incinerate, because the battery may explode.
