online, this port will be connected to the RF In/Out port (J4).
2.4.3.2 J4 RF In/Out
The RF In/Out port is the user interface to the RCU101 protection switch system. This
connection is an SMA F-type. The conversion to the N-type connector should be made at the
rack interface panel. If the system requires interface to an N-connector cable, an SMA-to-N
adapter is recommended.
2.4.3.3 J5 RF Termination 50-Ohm
The 50-ohm RF termination terminates the RF output of a redundant upconverter system or the
input of a redundant downconverter system for the converter that is in standby or faulted mode.
By removing the termination, access to the RF port of the standby converter can be obtained.
2.4.3.4 J6 RF Backup
The RF Backup connector is a type SMA-F that routes the RF signal of the backup converter to
the transfer switch in the RCU101. This connection is made via the supplied semi-rigid cable
assembly that is included with the RCU101.
2.4.3.5 J7 IF Termination 75-Ohm
The IF Termination is a 75-Ohm BNC type termination for the IF port of the converter that is in
standby mode. By removing the 75-Ohm termination, the operator can gain access to the IF port
of the converter that is currently in standby mode.
2.4.3.6 J8 IF Prime
This BNC-F connector goes to the IF connector of the primary converter. This connection is
made via the supplied IF cable assembly with the RCU101.
2.4.3.7 J9 IF In/Out
This BNC-F connector is the user IF interface to the redundant converter system.
2.4.3.8 J10 IF Backup
The IF Backup BNC-F connector connects to the IF port of the backup converter. This
connection is made with the IF cable assembly supplied with the RCU101 System.
2.4.4
Interfaces Common to the Converters
The RS485 equipment interface and the operator serial I/O interface found on the converter
hardware both play a role in the operation of the switch and are included here for continuity. For
further information, please refer to the converter manual for more information on these two
interfaces.
2.4.5
Operator Serial I/O (J8 on Converter Rear Panel)
Through the Operator Serial Port, the operator can gain access to all of the control features of
the converter. This enables the remote operator to configure the switch, set the gain and
frequency of the converter and interrogate status of the converter.
The Operator Serial Port is a DB 9-pin female connector at the rear of the converter. This port
provides serial interface that can be configured as either a RS232, RS422 or RS485 interface.
This port allows the user to remotely control all of the features outlined in the Serial Protocol
(Appendix B). The serial port comes configured as an RS-232 Serial port for DCE unless
