Nmea Type Of Gyro Connection; Connection For Satellite Modem - KNS Ku-BAND TX Installation And Operation Manual

3.6.3.3 NMEA Type of Gyro Connection

When the ship's gyro is of the NMEA type, use the 8
Table 3-6 Pins Used for the NMEA Type of Gyro
NOTE: KA-160 ACU can accept the various format of NMEA, as follow: HDT; HDG;
HDM. But NMEA signal must be matched the regular NMEA format as below.
$HEHDT,x.x,T*hh<CR><LF>
$HEHDG,x.x,x.x,a,x.x,a*hh<CR><LF>
*hh means checksum of format. If there is no this checksum, KA-160 ACU can't accept
the gyro signal.
3.6.3.4 RJ-45 Connection for Satellite Modem
The KA-160 ACU and the satellite modem exchange some data with each other, such
as GPS data, TX mute functions, external lock state, and external AGC.
Otherwise, please refer to the following:
GPS RS-232 Output
TX Mute: Supply DC voltage to the modem,
'0V' means that the antenna is in normal tracking status.
'5V' means that the antenna is mute or is in block area.
External lock bit: The TTL level can be set as '0' or '1'. Please refer to 'External Lock
TTL Level' of 'Installation Mode'
External AGC: The voltage range must be approximately 0~5VDC (the higher the signal
strength, the better the signal).
for voltage drop.
