Physical Installation
NOTE: The Installation section provides instructions pertaining to
the physical installation of the slave only. For complete cable and
TU/TM information, refer to Termination Unit Manual I-E93-911.
The DSM inserts into a standard Infi 90 Module Mounting Unit
(MMU) and occupies one slot. To install:
1. Verify the slot assignment of the module.
2. Verify that a dipshunt is in the slave expander bus socket
on the MMU back plane between the slave and master module.
3. Connect the hooded end of the termination cable from the
TU/TM to the MMU back plane. To do this, insert the connec-
tor into the back plane slot in the same slot as the one
assigned to the slave module. The latches should snap securely
into place.
4. Align the module with the plastic guide rails in the MMU;
carefully slide the module in until the front panel is flush with
the top and bottom of the MMU frame.
5. Tighten the two captive retaining screws on the module
faceplate. To remove the module, unscrew the module retain-
ing screws and carefully slide out.
WIRING CONNECTIONS AND CABLING
The DSM has three card edge connectors to supply logic power,
establish slave expander bus communication and provide digi-
tal inputs (P1, P2, P3 respectively).
Wiring
NOTE: You must install a dipshunt on the back plane of the MMU to
connect the slave expander bus between the slave module and
master module. Locate the modules so the bus can connect the
modules or they will not communicate.
WARNING
Disconnect power before installing dipshunts for slave mod-
ules on the MMU backplane (slave expander bus). Failure to do
so could result in severe or fatal shock.
AVERTISSEMENT
Couper l'alimentation avant d'installer les dipshunts sur la
plaque arriere du chassis de montage de modules (MMU).
Toute negligence a cet egard constitue un risque de choc pou-
vant entrainer des blessures graves, voire moretlles.
