Axiom 9 MFD to NMEA0183 VHF radio

[Chuck - Raymarine - Moderator]

Dan,

Q1. Is there a p/n for a cable that connects to the ST1 port on the ST1/STng converter but is bare wire at the VHF NMEA0183 end, or do I need to simply cut the ST1 connector off of the cable supplied with the E22158 converter kit?
A1. Raymarine does not separately offer this part. In contrast to the photo posted on Raymarine's website, the E70196 VHF NMEA 0183 to STng Converter Kit features bare leads on the cable which will be connected to the ST-STng Converter's SeaTalk port. Alternatively, the press-fit 3-pin plug may be cut off of the cable packaged with the E22158 SeaTalk1 & SeaTalkng Converter Kit and this cable may be interfaced in the manner specified within the referenced FAQ.

Q2. What is the max length of the NMEA0183 wiring between the ST1/STng converter and VHF radio? I'm trying to determine if I have to extend my STng backbone 20 ft to the VHF and have a short NMEA0183 connection with the E22158 STng to ST1 cable (ST1 end cut off), or can I run NMEA0183 cable 20 feet from the converter to the VHF.
A2. Raymarine has not specified a maximum length for extending the NMEA 0183 leads from the subject cable. However, 20' is well within the maximum length for extending Raymarine's NMEA 0183 cables before needing a NMEA 0183 expander.
