3. For TU or TM devices, connect the hooded end of the termi-
nation cable from the TU or TM to the MMU backplane. To do
this, insert the connector into the backplane slot in the same
slot as the one assigned to the digital output module. The
latches should snap securely into place.
4. Align the digital output module with the guide rails in the
MMU; gently slide the module in until the front panel is flush
with the top and bottom of the MMU frame.
5. Push and turn the two captive retaining screws on the
module faceplate one half turn to the latched position. It is
latched when the slots on the screws are vertical and the open
ends face the center of the module.
WIRING CONNECTIONS AND CABLING
The DSO has three card edge connectors to supply logic power,
establish I/O expander bus communication and provide digital
outputs (P1, P2, P3 respectively).
Wiring
Installing the module in the MMU connects the digital output
module to the logic power (+5 VDC), necessary to drive the cir-
cuitry, at P1. It also connects P2 to the I/O expander bus for
communication with the control module. P1 and P2 connec-
tions require no additional wiring or cabling.
NOTE: You must install a dipshunt on the backplane of the MMU to
connect the I/O expander bus between the digital output module and
the control module. Locate the modules so the bus can connect the
modules or they will not communicate.
Cable Connections
The IMDSO15 digital output module can use either a NTDI01
termination unit or a NIDI01 termination module for termina-
tion. Refer to Figure
to determine the cables to use with the
TU or TM.
WARNING
Disconnect power before installing dipshunts on the MMU
backplane. Failure to do so will result in contact with cabinet
areas that could cause severe or fatal shock.
