Common Question of SI-TEX MDA2
What is the MDA-2 receiver?
The SI-TEX MDA-2 is a metadata dual-channel parallel AIS receiver according to the listing. It receives compatible AIS information through parallel channels. Confirm antenna inputs, output connections, display, power supply, software, network, and AIS receiver system compatibility before installation.
What does dual channel mean?
Dual channel means the receiver monitors two AIS channels in parallel, subject to the unit’s specifications. Confirm antenna configuration, channel handling, output format, display, network, power supply, and software requirements before commissioning.
Does it transmit AIS data?
No. The MDA-2 is identified as a receiver, so it receives AIS traffic rather than transmitting the vessel’s own information. Verify antenna, display, wiring, power, and software before operation of this marine AIS transceiver receiver.
