RCU108 1:8 Protection Switch Description
Section One - RCU108 1:8 Protection Switch Description
1.0 Introduction
The Radyne RCU108 1:N Redundancy Control Unit provides backup protection for any number of online converters ranging from 2 through 8. The switch will operate with any Radyne Frequency Up or Downconverter product without distinction. The RCU108 Switch features plug­and-play simplicity of operation. Simply install the cables, tell the Backup to ‘Learn,’ and the protection switching is activated without complicated programming. Monitoring of all the online converters and the operation of the switch becomes the duty of the backup converter. Identical firmware in all Radyne converter products enables any converter plugged into the backup slot of the switch to assume the role of protection system controller.
As the system controller, the designated backup converter communicates with the online converters via the equipment RS485 interface. As a result, the switch contains a minimal amount of circuitry and is therefore very reliable. Control and monitoring of all the online converters and the switch itself can be performed through the operator RS232/422/485 serial interface. Once the backup converter is told to learn the primary converters, the backup will monitor the frequency, gain and channel settings of the online converter by polling the primary converters on a periodic basis. If any changes are made to the online settings, the backup converters will notify the user via the front panel or through the RS232/485 port. In the event of a failure of any online converter, the restored circuit will have the same online settings that were identified through the last learning process.
Menu programmable features in the backup converter allow various levels of backup priority to be set. A priority of 1 would be the highest level of protection, where a priority of zero or none means the converter would be logically removed from backup protection by the switch.
Manual backup from the front panel push-buttons on the switch allow the operator to fully test the circuitry and operation of the protection switch system exactly as if a fault had been issued by the converter being manually backed-up. Manual mode allows a converter to be removed or reinstalled into the system without the fear of interrupting the circuit that has been routed through the backup converter.

RCU108 1:8 Protection Switch Installation
Section 2 - Installation
2.0 Installation Requirements
The RCU108 is designed to be installed within any standard 19-inch equipment cabinet or rack,
and requires 2 rack units of mounting space (3.5 inches) vertically, and 17-inches of depth. Including cabling, a minimum of 20-inches of rack depth is required. The unit can be placed on a table or suitable surface if required.
WARNING: There are no user-serviceable parts or configuration settings located
inside the RCU108 chassis. There is a potential shock hazard internally at the power
supply module. DO NOT open the RCU108 chassis under any circumstances.
CAUTION: Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating satellite ground station equipment. This is especially true if the current RCU108 configuration settings are unknown, where incorrect setting could disrupt existing communications traffic.
2.1 Unpacking
The RCU108 was carefully packaged to avoid damage and should arrive complete with the following items for proper installation:
1. RCU108 Unit.
2. One cable set per paragraph 2.3.
3. Installation and Operation Manual.
2.1.1 Removal and Assembly
If using a knife or cutting blade to open the carton, exercise caution to ensure that the blade does not extend into the carton, but only cuts the tape holding the carton closed. Carefully unpack the unit and ensure that all of the above items are in the carton.
The RCU108 is shipped fully-assembled and does not require removal of the covers for any purpose in installation.
2.2 Mounting Considerations
When mounted in an equipment rack, adequate ventilation must be provided. The ambient temperature in the rack should be between 10° and 35° C, and held constant for best equipment operation. The air available to the rack should be clean and relatively dry.
2.3 Cabling
The RCU108 comes complete with all the cabling required to interface with the Upconverters or Downconverters. Refer to Figure 2-1 to become familiar with the rear panel connectors on the RCU108. Figure 2-2 shows a typical interconnection between four Upconverters and the RCU108. The list of supplied cables is as follows:
