Pyramid Communications Vehicular Repeater Interfacing and Connection Information (Application Notes) (This data was collected 20-Nov-20 and is subject to change.) Compiled by Robert W. Meister WA1MIK |
|
The Pyramid SVR-200 and SVR-250 Vehicular Repeaters are small microprocessor- controlled half-duplex radio transceivers with tone encoders and decoders. They can be easily interfaced and connected to many mobile radios. Nine wires are used to provide power, ground, control, and audio signals.
| Signal | Notes |
|---|---|
| 12V In | DC Power Input |
| COR In | Receive COR Signal From the Mobile Radio |
| Enable In | Remote Enable or Disable via External Switch |
| Ground | Audio and Power Ground |
| Local Mic Audio In | Allows local transmit without a remote radio |
| On Air Detect In | Tells the SVR that the Mobile Radio is Transmitting |
| PTT Out | PTT Signal To the Mobile Radio |
| RX Audio In | Receive Audio From the Mobile Radio |
| TX Audio Out | Transmit Audio To the Mobile Radio |
Of these nine signals, the ones that are needed by most repeaters are:
TX Audio Out, PTT Out, RX Audio In, COR In, 12V In, and Ground.
While the vehicular repeater may not be of much use to people building amateur repeaters, the interfacing information on Pyramid's web site does contain a lot of very useful and well thought-out wiring and configuration data. As you can see in the list below, most of their application notes are aimed at Motorola equipment, but they do have a lot of other popular brands as well.
These vehicular repeaters are often installed in fire trucks. The first unit on the scene activates its unit and selects the appropriate channel on the attached mobile radio. The firefighters then use portable radios on a different band to communicate with the vehicular repeater. When the base station transmits, the mobile radio in the fire truck hears it and causes the vehicular repeater to transmit that signal to the portable radios. When a firefighter transmits on a portable radio, the vehicular repeater hears it and causes the attached mobile radio in the truck to transmit that signal to the base station. Think of it as a range extender.
These devices have another interesting feature. As each equipped piece of apparatus arrives on scene and activates their unit, the other units detect the newcomer and they go into standby mode, letting the newly arrived unit take over the task of repeating. When an active unit leaves the area or a unit is disabled, the previously active unit takes over. This is all done seamlessly and with no user intervention. For more information about how these units work, read the appropriate service manual, available on Pyramid's web site www.pyramid.com.
The majority of their application notes are aimed at Motorola equipment, but they do have information for a lot of other popular brands as well.
A very nice Introductory Overview can be found here.
