Note 1
The standard NMEA output rate is 1x/second. When Output
INSTR is set to J300X-1 (default), the output port, TX1, will have
an output rate of 5x/sec. for HDG or HDT (heading) messages.
The RSA (rudder angle) message is always 5x/sec.
Note 2
NMEA OUTPUT 2 on J300X has a constant output rate of
10x/sec. for HDG or HDT. Both port 1 and 2 are still sending
HDM at 1 Hz. HDM is an obsolete sentence but some older
equipment may still use it.
The Interface Menu presents these names so that they can be
assigned to a hardware input or output port. Each abbreviated
name is then presented in appropriate locations of the USER
