SECTION 5
North Star HSIO-4
TROUBLESHOOTING
If you lose communication with any peripheral
device connected to the HSIO-4 board, you must
first determine whether the cause of the
failure is in a specific peripheral device and
its cabling to the computer or in the HSIO-4
board itself.
Use the following procedure to trace the cause
of a communications failure:
If peripheral devices are connected to more
1.
than one I/O port and communication to all
the connected peripherals has failed, this
indicates that some part of the HSIO-4 not
specific to a particular I/O port may be at
fault. In this case, follow the procedure
outlined in Section 5.3.
If you lose communication with only
2.
one peripheral, you should check that the
configuration of the peripheral and the
cable connection to the computer have not
been altered. Make sure the connectors at
both ends of the cable are firmly seated.
Retry establishing communication with the
peripheral.
If communication with the peripheral is
3.
still lost, disconnect the cable from the
malfunctioning port, re-connect it to one
of the other I/O ports that is functioning
properly, and retry establishing
communication through the new I/O port.
4.
If communication is still lost, this
indicates that the problem is with the
peripheral device itself or the connecting
cable.
5.
If communication is successfully
established, this indicates that some part
of the HSIO-4 board specific to the I/O
port first tested is at fault. Follow the
procedures in Sections 5.1 and 5.2.
