3.7.3 RS232 CABLE (NOT UTC CONTROLLERS)
TO MODEM
The RS232 Cable to the modem is a single moulded cable (part number
667/7/25175/000).
The RS232 Cable connects the Integral Facilities Processor PCB to the modem.
It connects to PL3 (see Figure 1 on page 13) on the PCB and the 25-way D
Connection on the modem.
If the modem is provided with a 9-way D socket then it will have a 9-way to 25way Converter fitted such that the RS232 cable can be plugged into the 25-way
socket on the Converter.
The RS232 Cable should be connected to the Integral Facilities PCB and the
upper screwlock on the right angle connector tightened to the PCB connector.
The RS232 Cable should then be connected to the modem (or Converter) and
both screwlocks tightened to the modem connector (or Converter connector).
For routing of the RS232 and the Power and Local I/O Cables in the T400
cabinet, refer to
Figure 5 on page 17 and the notes below.
In a small T400 outercase (i.e. a Pelican T400), the cables are routed along the
side of the top PCB module to the back of the cabinet and the modem panel.
In a large T400 outercase (i.e. an Intersection T400), they are routed by the side
of the PCB modules to the panel at the rear.
In the T400 and ST800 Intersection Controller Large TfL TCUG Cabinets the
RS232 cable leaves the IFC and passes under the PCB rack before crossing the
controller and connecting to the modem. The Power and I/O Cable is passed
between the IFC and the PCB to its left, exiting the back of the PCB rack.
In the T400 Pelican Small TfL TCUG Cabinet the RS232 cable leaves the IFC
and is fed through a cut-out in the right hand side of the front panel before
crossing the controller to the modem. The Power and I/O Cable is passed
between the IFC and the PCB to its right, exiting at the back of the PCB rack.
In the ST700 Pelican Small TfL TCUG Cabinet the IFC cables run along the top
of the rack from the IFC card on the right to the modem mounting panel on the
left.
All cables should be secured into position using cable ties.
