[CA] [CA11] E120 to Axiom 12 Does this look ok

Q1. As was suggested I will be attaching the existing the Raystar 125 GPS Antenna to a connector block that will be be connected to the existing Seatalk network. hile looking at my diagram posted in my earlier post I see that there is an error in the connection of the Raystar 125 to the block. The green should be attached to the red not to the yellow. Am I correct that the diagram is incorrect?
A1. Indeed you are correct. The RS125's red and green leads should both be connected to SeaTalk red. The RS125's brown and black/bare leads should both be connected to SeaTalk black/shield. The RS125's yellow lead should be connected to SeaTalk yellow.

Q2. Since I am guessing that the output of the Raystar 125 is NEMA 0183 is the Sea talk to NG converter actually converting Seatak to NEMA 2000 (NG)?
A2. Depending upon how the RS125 has been interfaced to the system, it will support either SeaTalk or NMEA 0183 communications, but not both simultaneously. When interfaced as indicated within the response to Q1, the RS125 will support SeaTalk communications.

Q3. If that is true why couldn't I use that to same connector block to attach my other NEMA 0183 (DSC and AIS) to convert my data to NEMA 2000 (NG) instead of using an Actisense.
A3. Negative. When interfaced in a manner supporting NMEA 0183 communications, the Raystar 125 GPS sensor will support 4800 BAUD NMEA 0183 communications, rather than 38400 BAUD NMEA 0183 communications as is supported by your SH VHF/AIS receiver. Accordingly, these products should not be interfaced to the same terminal strip and the previously discussed Actisense NGW-1-ISO-AIS will be required to interface the SH VHF/AIS receiver to the system.
