Summary
The Ocean TRx4-500, launched by Israel's Orbit on the market, is a communication service platform using satellites.This system consists of several accessories as follows, among them, ADMx and BDMx are multiplexer device that receives a signal Above Deck and sends it to the control unit of Below Deck.
Multiplexer Collects multiple signals in one place, selects the desired signal and outputs it.
ADMx(Above Deck Multiplexer) A device mounted on the deck of a ship
BDMx(Below Deck Multiplexer) A device installed under the deck of a ship
BDMx+ADMx Test Data (with 1M Cable)
