Page 3: Introduction
Introduction Congratulations on selecting the RVS-8 voter. This system allows you to add up to eight satellite receivers to your repeater system. It selects the one with the best signal-to-noise ratio and channels the audio and Carrier Operated Relay (COR) output to your repeater input. A wide variety of options is available via the front-panel controls and display. -

Page 6: Installation
Installation Your RVS-8 is intended for indoor use only; it is not water resistant. If you install it in a remote location, you must insure that it is protected from moisture and temperature extremes. 1. Connect the audio output from each of your receivers to the screw connections on the header labeled "Audio In J5". -
Page 7: Setup
Setup Setup your RVS-8 via the front panel buttons and LDC display. Setup data is stored in non- volatile EEPROM, and remains intact when power is removed. Hysteresis The hysteresis level is the amount of signal-to-noise ratio improvement needed over the currently voted site for a new site to be voted. - Page 8 Disable Active State You can choose whether a receiver is disabled by means of a high or low voltage state input to J3. This selection can be made for each channel; that is, you can set each channel to either high or low separately.

Page 9: Operation
Operation On power-up, the display shows a title screen and current firmware version for a few seconds, then the default screen: "Current Voted". The currently voted receiver is displayed. As the repeater operates, the red COR LED on the front panel will light when the repeater is activated. The Current Voted display continuously updates as the system switches from receiver to receiver. - Page 10 Most Voted: Displays the channel most often voted, out of the last 100 COR cycles. This count is reset when DC power is cycled. Least Voted: Displays the channel least often voted, out of the last 100 COR cycles. This count is reset when DC power is cycled.

Page 11: Application Notes
The following diagram shows a basic setup with eight satellite receivers. Typically, one of the receivers is the "main" receiver, co-located with the transmitter. The other receivers are usually "link" receivers bringing audio from remote satellite receivers. Audio Receiver 1 Audio RVS-8 Receiver 8 Audio Output Repeater Transmitter... - Page 12 Should the need arise, you can use up to 64 satellite receivers by "cascading" eight RVS-8 voters. Each of the eight voters can input eight receivers, for a total of 64. The outputs of these eight RVS-8 voters are then input to a ninth RVS-8 unit which provides final selection of audio and COR outputs to the repeater transmitter.
