Q
When the GP39 is connected to the SCX21, what additional displays are
available on the GP39?
Q
Does the SCX21 output Heave information for my Furuno Sounder?
Yes, the SCX21 outputs Heave along with pitch and roll.
Q
What is the update rate of the SCX20 position/heading information?
The SCX21 updates position and heading at 10hz.
Q
Can the output rate be changed and or individual sentences turned off?
Yes. Sentence output rates can be individually changed or turned off completely using a
connected GP39, or via a PC running Tool software.
Q
Is the SCX21 compatible with the TZtouch2/3 sensor management
menu?
No. TZT2/3 Sensor management is done over the NMEA2000 bus. The SCX21 is not a
NMEA2000 device.
Q
Is the SCX21 affected by GPS blockage and or multipath?
Any GPS sensor or satellite heading sensor can be affected by blockage and or multipath. The
SCX21 decreases these affects by using 4 internal GNSS antennas creating 6 baselines, the
most currently available on the market, for measurement. While the SCX21 can use all 6
baselines for heading, it does not have to. It can calculate heading using only two baselines.
The chance that all 6 baselines would be affected by multipath is decreased. This makes the
SCX21 much more resistant to these issues.
