Troubleshooting

MP150 Rev. E3 07/2013 55

Checkpoint

Possible Cause / Solution

• Switch on/off the scanner’s power.

• Software is not to be launched during the initialization time of the scanner (about 30 s).

• Use the network administration utility Ping to test the reachability of the scanner. Call the

Windows <Command Prompt> and execute ping 192.168.42.30 (exemplary IP address)

• Use the network protocol Telnet to provide a bidirectional text-oriented communication to the

scanner by using the scanner specific commands. Call the Windows <Command Prompt> and

execute telnet 192.168.42.30 2727 (exemplary IP address and port).

Note: Telnet is not available on all Windows computers by default!

Serial

Communication

via COM port

• Verify correct C

port. If existing use another C

port on the computer.

• To avoid communication problems the properties of all used COM ports must be changed as

follows:

<Start> <Settings> <Control Panel> <System> <Hardware> <Device Manager> <Ports (COM &

LPT)> <Communications Port COMx> <Ports Settings> <Advanced> <Receive Buffer>: Low

• In case of using plug-in serial cards, disable <CTS/RTS> for the Auto Flow Control.

<Start> <Settings> <Control Panel> <System> <Hardware> <Device Manager> <Ports (COM &

LPT)> <Communications Port COMx> <Ports Settings> <Advanced>

• Avoid the use of third party USB/RS232 converters!

• Ensuring the RS232/485 converter is close to the PC (and not to the scanner)

• In case of communication errors, the baud rate should be reduced step by step.

• Software is not to be launched during the initialization time of the scanner (about 30 s).

• On some computers, the performance of the software can be increased dramatically by switching

off the hardware graphic acceleration:

<Hardware acceleration>: None

• A too high display resolution can cause problems. Test temporarily a setting of 800x600 pixel at
