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
OM
port. If existing use another C
OM
port on the computer.
•
To avoid communication problems the properties of all used C
OM
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).
PC
•
On some computers, the performance of the software can be increased dramatically by switching
off the hardware graphic acceleration:
<Start> <Settings> <Control Panel> <Display> <Settings> <Advanced> <Troubleshooting>
<Hardware acceleration>: None
•
A too high display resolution can cause problems. Test temporarily a setting of 800x600 pixel at
