-PC Support & CA/400

Error 0042 0043 - Online queue data incorrect; -Diagnostics

You may encounter Diagnostic error 42 or 43 above or intermittent “line drops” if you are using twisted-pair wire or incorrect cable termination. For twisted-pair wire, try to reduce the number of cable runs to the twisted-pair hub, or move the problem connection to a port on the hub with only two or three other connections. Another solution might be trying a different brand of balun.

This Diagnostic error message generally indicates that your PC motherboard is not supplying negative 5 volts to the Adapter Card. Please try the Adapter Card in another motherboard or contact the motherboard manufacturer about the availability of negative 5 volts at the ISA slots.
