1. make sure the mca is not connected to the scanner, communication cable or host and unfasten the case.
2. reposition the shunt on jp1 to pins 1 and 2 and close the case.
the factory setting of jumper 1 (jp1) is on pins 2 and 3. to direct power for the scanner from the host device, position the jumper on pins 1 and 2.
pin 1 of the mca provides a connection point for various ground/shield ground configurations on different metrologic products. internal jumper jp2 of the mca gives end users the option of changing pin 1 of the db9 into a no connect (nc). simply remove the jumper from the pins, then pin 1 of the db9 becomes an open/no connect pin.
jp2 should always be in place for ocia applications.
1.*to maintain compliance with applicable standards, all circuits connected to the scanner must meet the requirements for selv (safety extra low voltage) according to en 60950.
2.**to maintain compliance with standard csa c22.2 no. 950/ul 1950 and norm en 60950, the power source should meet applicable performance requirements for a limited power source.
3. plug the 4 position ground jumper into the power supply connector.
4. turn off the host system
5. if using a communication cable, connect the cable to the correct port on the host device and the mca.
if the host device is an ibm compatible with a male 9-pin serial port, connect the mca to the port.
there is an optional cable (mlpn 51-51236) that is available for ibm pc applications where the mca will not fit at the back of the computer.
6. plug the scanner's coil cable into the mca.
7. turn on the host system.
1.to maintain compliance with applicable standards, all circuits connected to the scanner must meet the requirements for selv (safety extra low voltage) according to en 60950.
2.**to maintain compliance with standard csa c22.2 no. 950/ul 1950 and norm en 60950, the power source should meet applicable performance requirements for a limited power source.
