Damage, the doc makes it clear that only the GGA and RMC sentences are exploitable, therefore no way to send AIS targets (VDM sentence) via the cable. It would be useful for stationary use at the chart table, wire connected to a conventional multiplexer, rather than a wireless access point or PC IAIS (power hungry). Ideally such a cable should also help to recharge the beast!
