Routing of the cables between the converters and the switch is depicted in Figure 2-2. Note that
the RF/IF cabling included with the switch does not include cables to other panels in the rack.
2.4 Hardware Interfaces
Hardware interfaces between the online and backup converters and the switch equipment
include the RF interface, IF interface, Switch Interface, and Equipment RS-485 interface. In
addition to the above, the operator has access to all converter equipment in the system including
the switch via the operator RS-232 interface on the converter.
2.4.1 Backup Switch Interface (Converter Interface) Connector (J16 - J24)
The protection switch interface connector is a DB 15-pin connector that connects each converter
with the redundancy control unit. This cable serves as a direct link for each converter in the
configuration whether they are the primary converter or the backup unit. The pinout of the switch
is as follows:
Note: The DB 15-pin connector is identified as J5 on the converters and connects to the
Redundancy Control Unit J16 through J24. J16 connects to the backup converter, J17 connects
to converter #1, J18 connects to converter #2, J19 connects to converter #3, etc.
