According to the manual, the interface "may be used with any radio
navigation system that uses NMEA the 0180, 0181, or 0183 standard," so it

I dunno. The older units used a proprietary protocol called "Sea Talk"
(hence the "ST") and wouldn't understand NMEA (sp???). To interface the

required an interface box to convert the Sea Talk back and forth.
