ACR&Artex TerraFix 406 GPS PLB - Manual (Page 17)

Y1-03-0174 Rev. E 16
Q. Does my GPS unit have to be set up in a special way to transmit position coordinates via the
NMEA 0183 Interface?
A. For the GPS to transmit data, go to GPS setup and make sure the NMEA 0183 output is turned on and
the GGA NMEA sentence is selected or turned on. Consult your GPS user’s manual for information on
configuring the NMEA output.
Q. What is the maximum length my GPS cable can be?
A. ACR Electronics recommends a maximum length of 400 feet using 24 AWG wire. Contact your GPS
owner’s manual for more detailed information.
Q. What happens if I plug the GPS into the PLB first and press the GPS I or I/O button without
waiting for the GPS to acquire satellites?
A. The PLB will function normally in the off position, but will not store GPS coordinates. As soon as the
GPS has acquired satellites the data will be transferred to the PLB. If the PLB is activated no GPS data
will be accepted and your PLB will rely on the LEOSAR satellites to obtain its position by using Doppler
shift.
Q. What happens if I have downloaded GPS into my PLB and the Onboard GPS engine acquires new
GPS data (P/N 2798.4 only)?
A. If external and internal GPS are present, the internal GPS data will have priority at activation. If the
internal GPS has not been able to acquire your LAT/LON coordinates prior to your first burst, the
downloaded GPS coordinates will accompany the UIN to the satellites. Once good navigational
coordinates are obtained by the onboard GPS, these coordinates will be updated into the distress
message and the downloaded coordinates will be eliminated.
Q. How long does the PLB hold data in memory?
A. 4 hours. If new GPS data has not been downloaded, the TerraFix will return to default mode and utilize
the LEOSAR satellites to obtain the position using Doppler shift.
Q. How much power is needed to run the IR LED on the GPS cable?
A. The minimum power needed is 3.3V
DC
and 2mA
