Chapter 1. INTRODUCTION
1.1 Overview
The RRS11 Solid State Transfer Switch offers IF or L-Band redundancy for the DM240XR in a
simple straight forward plug and play design. The RRS11 includes monitor ports that allows the
user access to the online and offline ports. The RRS11 also includes front panel LEDs that
indicate online status of the modulator.
The RRS11 can be configured to support 70/140 MHz or L-Band System. An external power
source is not required. DC power and fault status is supplied to by each DM240XR. The RRS11
will trigger a switchover in the event that the modulator faults. Figure 1-1 through 1-4 illustrates
the front panel and rear panel of the RRS11 models.

Chapter 2. Installation
This section provides unpacking and installation instructions, and a description of external
connections, status and contact closure alarm information.
2.1 Installation Requirements
The RRS11 Solid-State Transfer Switches is a standard one rack unit (1RU) high (1.75
inches/4.45 cm) vertically, 19 inches (48.3 cm) wide, and 17 inches (43.2 cm) deep. The RRS11
Switch is installed between two DM240-PIIC or DM240XR modulators. The supplied cables
lengths only allow for this configuration.
There are no user-serviceable parts or configuration settings located
inside any Solid-State Transfer Switch Chassis. There is a potential
shock hazard internally at the power supply module. DO NOT open the
Solid-State Transfer Switch Chassis under any circumstances.
Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating ground station equipment. This is
especially true if the current Solid-State Transfer Switch configuration
settings are unknown, where incorrect settings could disrupt existing
communications traffic.

2.2 Unpacking
The RRS11 Solid-State Transfer Switch was carefully packaged to avoid damage and should
arrive complete with the following items for proper installation:
RRS11 Solid-State Transfer Switch Unit
RRS11 Test Data Sheet
Interconnect Cables (IF, Monitor and Control)
Installation and Operation Manual
2.2.1 Test Data Sheet
Each RRS11 Solid-State Transfer Switch is shipped with a Test Data Sheet. This report contains
information on the results of the Switch quality control testing. The report also includes
information pertaining to the system settings that were made at the factory. Radyne Corporation
recommends that the user save this report for future reference.

3.2 Operating Procedures
The Solid-State Transfer Switch is designed for minimal operator intervention and control during
normal operation. After initial setup, the unit should operate in a relatively ‘transparent’ manner,
providing trouble-free backup of the online modulators
3.3 Solid-State Transfer Switch Backup Operation
The RRS11 Switch monitors the fault status from each modulator. Each DM240-PIIC or
DM240XR supplies DC voltage and fault status to the RRS11. An additional DB9 connector has
been added to the rear panel of the DM240-PIIC or DM240XR that provides a wiring port to the
external switch. Each modulator is capable of powering the switch through a current limited,
diode or’ed power signal. Either of the DM240s is also capable of commanding the switch to the
prime or backup state, as well as monitoring in which state it is. Additional menus are available
on the DM240 front panel menus or remote port that allow user to control switching parameters.
In normal operation, the M&C in the backup modulator monitors the prime for faults. If one is
detected, it will automatically cause the switch to place the backup on-line. The switch is non-
revertive. That is, once a switch occurs, it requires a manual command (either through the M&C
or from the front panel) to return the prime unit to an on-line status. This will be the default
operation, but the switching software is capable of implementing revertive switching as well.
Either modulator will be capable of changing the state of the switch (assuming it is not faulted).
This can be done remotely or from the front panel. Remote control will occur through the
standard Ethernet M&C interface implementing SNMP. The switch connectors are listed in
Table 3-1 and 3-1A.
