MV-ELD

MV-ELD 1/2 and MV-ELD 2/2 are a pair of mounting boards provided with original 2-slot and 4-slot MVS cabs to attach the marquee's electro-luminescent panels. Each one can hold 2 panels.

They don't use any components except connectors.

Both boards are different:
 * The MV-ELD 1/2 board has two connectors: one for the MV-ELA board, and another one for chaining the MV-ELD 2/2 board.
 * The MV-ELD 2/2 board has only one connector.

The 3 or 6 panel version is the MV-ELC.
