RCS20 M:N Redundancy Switch Operation Section 3 – Operation 3.0 Principles of Operation This chapter provides additional basic information on the RCU20 and IFS20 hardware and internal operation. 3.1 RCS20 Major Assemblies The RCU20 Redundancy Control Unit contains the modules that control and monitor the operation of the M:N Switch System. The RCU20 is composed of the following major assemblies and components: 1. 2. 3. 4. 5. 6. 7.
Operation RCS20 M:N Redundancy Switch 3.4 IFS20 Major Assemblies The IFS20 IF Switch interfaces the IF signals of the Modems with the earth station IF system and provides back-up switching. The unit provides all of the switching relays, signal combiners and splitters, terminations and interconnecting cables that are necessary to connect any combination of up to eight Modulators and Demodulators to eight independent uplink and eight independent downlink Transponders. The IFS20 has no internal power supply.
RCS20 M:N Redundancy Switch User Interfaces Section 4 – User Interfaces 4.0 Operating Procedures Operation of the RCS20 consists of controlling the unit operating parameters and monitoring status and responses via one of the control interfaces. There are three possible control options for the modem: Front Panel Control Terminal Mode Control Command Interface Control Any of these methods may be used separately or together to monitor and control the RCS20. 4.
User Interfaces RCS20 M:N Redundancy Switch 4.1.3 Front Panel Keypad The front panel keypad consists of eight areas, as shown in Figure 4-1 and listed in Table 4-1. Figure 4-1. Table 4-1 Item No. Label 1 MODEM 2 (None) 3 RESET ALARMS Reset Alarms. This key resets all RCS20 current and latched major and minor alarms. 4 MODEM SELECT Select Current Modem. This key selects which modem is currently being controlled by the Modem group of keys.
RCS20 M:N Redundancy Switch User Interfaces The ten keys contained in the MODEM and SWITCH are used to view and change a particular set of control parameters as described by the label next to the key. Each of these keys are used to display a series of menu trees that are displayed on the LCD and used to view and enter control parameters. These keys and their corresponding menus are described separately below: 4.1.3.
User Interfaces RCS20 M:N Redundancy Switch 4.1.3.9 SWITCH-MONITOR/ALARMS Pressing this key brings up a series of menus on the LCD that allow monitoring of major and minor alarms and control of alarm masking for the RCS20. 4.1.3.10 SWITCH-TEST Pressing this key brings up a series of menus on the LCD that allow testing of the RCS20 configurations and connections. 4.1.
RCS20 M:N Redundancy Switch User Interfaces familiar with the basic concepts and operations. Front panel control is implemented as a series of data entry screen. The data entry screens (“screens”) are organized into several groups that contain related parameters and status values. Screens allow the modification of control parameters, display of status parameters, or both. Different screens will be displayed on the front panel based on key presses from the front panel.
User Interfaces RCS20 M:N Redundancy Switch Never apply power to the slide out power supply modules unless they are firmly seated in the RCU20, as there is a potential shock hazard at the AC/DC Converter within the module. Turn the unit on by switching both AC power switches (located above the power entry connectors at the rear of the RCU20) to the on position. At power-up, the switch processor will perform a selfdiagnostic before beginning the primary monitor/control program.
RCS20 M:N Redundancy Switch User Interfaces 4.5.1.1 Changing parameters from the Front Panel Whenever there is a parameter that can be changed or edited from the front panel, the first character of the parameter value will highlight with a blinking box. This box is called the cursor, and the cursor defines what parameter is currently being edited. If there are several parameters on one screen, two of the soft keys will be labeled <--- and --->.

User Interfaces RCS20 M:N Redundancy Switch 4.7 Host Computer Remote Communications Control and status messages are conveyed between the RCS20 and the subsidiary modems and the host computer using packetized message blocks in accordance with a proprietary communications specification. This communication is handled by the Radyne Link Level Protocol (RLLP), which serves as a protocol ‘wrapper’ for the RM&C data.
RCS20 M:N Redundancy Switch User Interfaces - The Destination Identifier specifies the multidrop address of the device(s) to which the message is sent. - The FSN is a tag with a value from 0 through 255 that is sent with each message. It assures sequential information framing and correct equipment acknowledgment and data transfers. - The Operation Code field contains a number that identifies the message type associated with the data that follows it.
User Interfaces RCS20 M:N Redundancy Switch 4.7.3 Frame Description and Bus Handshaking In a Monitor and Control environment, every message frame on a control bus port executes as a packet in a loop beginning with a wait-for-SYN-character mode. The remaining message format header information is then loaded, either by the M&C computer or by a subordinate piece of equipment requesting access to the bus. Data is processed in accordance with the OPCODE, and the checksum for the frame is calculated.
RCS20 M:N Redundancy Switch User Interfaces RESPONSE OPCODE DESCRIPTION OPCODE Good Message 00h Bad Parameter FFh Bad Opcode FEh 4.7.5 Collision Avoidance When properly implemented, the physical and logical devices and ID addressing scheme of the COMMSPEC normally precludes message packet contention on the control bus. The importance of designating unique IDs for each device during station configuration cannot be overemphasized.

RCS20 M:N Redundancy Switch Maintenance Section 6 – Maintenance 6.0 Periodic Maintenance and Troubleshooting The RCS20 requires no periodic field maintenance procedures. The unit has no adjustments, and all configuration information is digital and stored in nonvolatile EEPROM. Should a unit be suspected of a defect in field operations, the proper procedure is to first to follow the basic troubleshooting guide below. If this does not cure the problem, replace the unit with a known good unit, if available.
Maintenance RCS20 M:N Redundancy Switch Each of the slide-in power supply modules houses AC fuses that are accessible from the rear of the unit. The fuses can be replaced in the field while maintaining redundancy protection for modems connected to the RCS20 by changing the fuses for one power supply at a time. Be sure to replace the fuse with one of the same type and rating. Failure to do so may result In damage to the equipment and may result In a fire hazard. 6.
RCS20 M:N Redundancy Switch Maintenance Table 6-2. Major Alarm Matrix 6.2.2 Minor Alarms Minor Alarms indicate a failure condition that does not immediately result in loss of service on one or more primary satellite channels. However, a minor alarm may indicate that there is a loss of redundancy protection for one or more channels. The RCS20 indicates a Minor Alarm by illuminating the MINOR ALARM LED on the front panel, and closing a relay on the rear panel ALARM connector.
Maintenance RCS20 M:N Redundancy Switch Table 6-2. Major Alarm Matrix 6.2.3 Alarm Masks Each of the Major and Minor Alarms listed above can be ‘masked’ so that the alarm will not result in an indication on the front panel LEDs or the ALARM connector. However, the alarm will be displayed in any of the control modes (Remote, Terminal, or Front Panel). This feature is very helpful during debugging or system testing to lock out a failure that the user is already aware of.
