Link failure
SCANport failure:
Poor cable connection
does not allow proper
port identification or
the SCANport device
isn’t allowing the
configured I/O
connections.
1. Check all SCANport cables and connections to the
SCANport device.
2. Ensure datalinks are not enabled on a product that
doesn’t support datalinks. Or, ensure that a particular
datalink is not already being used by another adapter on
the same SCANport device.
In either case, the adapter must be properly configured
and power cycled after the problem is fixed.
