Connecting the MH941 Hand-Held Scanner to the Fixed
Scanner and Host Device
In order for the MH941 scanner to maintain compliance with applicable
standards, all circuits connected to the scanner (Example: power supply, host
system, etc.) must meet the requirements for SELV (Safety Extra Low Voltage)
according to EN60950.
1. Make sure the host system is turned off.
2. Connect the head cable of the MH941 hand-held scanner to the cable
terminated with a 9-pin connector attached to the fixed scanner.
3. There are two ways to connect the fixed scanner to the host device
completely:
! If the fixed scanner will be powered by the host system, connect the
communication cable to the host device.
! If the fixed scanner will be powered by an external power supply, the
socket-outlet can be installed near the equipment and can be easily
accessible. Check the AC input requirements of the power supply to
make sure the voltage matches the AC outlet. Connect the scanner’s
communication cable to the scanner. Connect the cable to the host
device. Power up the scanner by plugging in the power supply.
4. Power up the host system.
Note: When the MH941 scanner first receives power, it will immediately
go through a self diagnostic routine, then the green and red LEDs will
flash, and the unit will beep once.
