Troubleshooting
Corrective Action
• Apply power to the 1769-SM1 module.
• Apply power to the DPI or
SCANport-supported drive.
• Connect the 1769-SM1 module to the
drive using a 1202-C* communications
cable.
• Verify that the 1202-C* communications
cable is securely connected.
• Cycle power to the drive.
• Avoid disabling a channel after enabling
it to pass I/O.
Important: Cycle power to the drive after
making any of the following corrections:
• Verify that all 1202-C* communications
cables are securely connected and not
damaged. Replace cables if necessary.
• Verify that the drive supports Datalinks.
• Configure the 1769-SM1 module to use
a Datalink that is not already being used
by another peripheral.
No action required. Normal behavior if I/O
is not enabled.
