The Repeater allows one Control Head to control two Display Boards.
A Repeater is needed since using a phone jack splitter will not work reliably; because both the Control Head and the Display Board are transceivers (they send data in both directions).
The Repeater includes two phone cords and one Display Board.
The Repeater works with both the Mega Dial and the Mega Dial Panel, and is also compatible with 12 Volt and 16 Volt batteries.
All Repeater cases are Black.
The accompanying Display Board is available in Black or Chrome with Red, Blue or Green LEDs.
