error if the I/O expander bus is not connected between it and
the digital output module. Verify the bus connection on the
MMU backplane.
If the I/O module is faulty, replace it with a new one. Refer to
the
procedures to replace a DSO module.
MODULE PIN CONNECTIONS
The digital output module has three connection points for
external signals and power (P1, P2 and P3). Tables
show the pin connections.
WARNING
Disconnect power before installing dipshunts on the MMU
backplane. Failure to do so will result in contact with cabinet
