Description
Rack attachment bracket for the IDU. One ear has a grounding stud for IDU
grounding. The ears can be fitted either side and provide flush-with-rack-front
mounting.
2-pin D-series 2W2C power connector for all IDUs. Includes screw fasteners.
5A time-lag fuse and power on/off switch. ON is when the fuse head is in the
vertical position; OFF is when the head is rotated to the horizontal '0' position.
Type N female connector for jumper cable connection to the surge suppressor
located at the cable entry point to the building.
RJ-45 connector provides a V.24 serial interface option for 9500 MXC CT. It
supports a default IP address, which means knowledge of the Terminal IP
address is not required at login.
The DB-9 connector provides one synchronous or asynchronous data service
channel. Selection of synchronous (64 kbps) or asynchronous (max 19.2 kbps)
is via CT.
HD-15 connector provides access to two TTL alarm inputs and four form C
relay outputs. Connections are mapped in CT.
