Comments:
The following changes provide the correct information for jumper placement when choosing
between RS-232 or -485. This inform at ion will be incorporat ed into the next revision.
Change Specifics:
3.4.1 Communications Link
The terminal functions can be remotely controlled and monitored via an RS-485 or RS-232
communications link.
• The RS-485 interface makes it possible to operate 255 terminals on a common communications
link.
• The RS-232 interface is used to communicate with a single terminal.
The M&C module must be hardware configured on the M&C board to one of the two interfaces. Refer to
the following table for jumper placement at JP1:

INTRODUCTION
1
This chapter provides an overview, included assemblies, and specifications for the
RSU-503 (Figure 1-1).
Note:
Refer to Appendix A for information on the RSU-503L, a low-loss version of the
RSU-503.
Figure 1-1. RSU-503
Rev. 8 1–1
Introduction RSU-503 Redundancy Switch Unit
1.1 Overview
The switch is a fully automated 1:1 protection switch designed to work with the
following EFData Radio Frequency Terminals (and their amplifiers):
• RFT-500
• RFT-505
• RFT-700
• RFT-705
• RFT-1200 (for RSU-503L information, refer to Appendix A)
• RFT-1225 (for RSU-503L information, refer to Appendix A)
• KST-2000 (for RSU-503L information, refer to Appendix A)
Note:
All references in this document to “RFT” apply to all the models listed above.
The switch has a weather resistant enclosure which houses the indicators and controls to:
• Switch RFTs and LNAs
• Command the waveguide switch to toggle
Specifically, the switch performs the following functions:
Controls waveguide/coaxial switch positions
•
Provides independent uplink and downlink paths
•
Routes the IF input to the online RFT
•
Routes the IF output from the online RFT
•
Initiates a switch-over in Auto mode by monitoring RFT faults
•
Supplies test ports for testing the standby channel
•
Receives RS-232/485 serial commands, routing them to the appropriate RFTs,
•
and returns their responses
Receives its own RS-232/485 command set for Auto/Manual mode, A/B online,
•
and address select
• Provides FORM-C relay contacts for Summary Fault status
Power is supplied by one or both RFTs.
1–2 Rev. 8
RSU-503 Redundancy Switch Unit Introduction
Although there are no external indicators or switches (due to the nature of the
weatherproof housing), there is an access panel that can be removed, allowing use of
internal switches and indicators (refer to Chapter 4 for more information).
Note:
The internal indicators and switches are only used for factory testing and
troubleshooting.
The system, during setup and while running, is intended to be controlled remotely.
Refer to Figure 1-2 for an interconnection block diagram of the switch.

2.3 Switch Installation
At the customer’s discretion, the switch can be installed anywhere on or near the
antenna. The supplied hardware allows the installer a wide range of installation
alternatives, including:
Vertical pole (e.g., mast) (either square or round). This is the most typical
•
installation.
Within the hub of a large antenna.
•
Spar (i.e., rectangular bar) on the antenna structure.
•
The switch is designed to be mounted with the interface connections facing the ground.
For custom installations, refer to Figure 2-1 for dimensions of the RSU-503.
