Using a GPS receiver
A GPS receiver can be connected to the serial input of the D1000X, provided it meets the
requirements shown in the section “D1000X Specifications” in this manual. To connect the
D1000X to the GPS receiver, a “serial cable” is required. Such cables are available from
Pettersson Elektronik and it should be connected to a “serial PC cable” (with a 9-pole female
D-sub connector) from the GPS receiver. Please note that only GPS receivers with a
serial/RS-232 output can be used and that you may have to alter the settings of the GPS
receiver to meet the requirements of the D1000X (NMEA mode/4800 Baud). In order to avoid
the bulky connectors joining the two cables, a dedicated cable can be manufactured. For
information about this, please contact Pettersson Elektronik.
The GPS receiver should be connected to the D1000X and turned on before the D1000X is
turned on. The D1000X will check for a connected GPS receiver each time it is turned on (the
text “Searching GPS…” is shown) and if a GPS receiver is found, the GPS position
information and time will briefly be displayed and the GPS function in the D1000X will be
enabled until the D1000X power is turned off or the GPS receiver is disconnected/turned off.
When the D1000X has found a connected and working GPS receiver, this will be indicated
with a “G” to the right of the time on the display. A connected GPS receiver with poor
reception quality will be indicated as “0” and with no connected GPS receiver, no indication
is made on the display.
When a GPS receiver is connected to the D1000X, the current position data and time will be
stored in each of the recordings made. The recorded values are taken immediately before the
recording started. To retrieve this information, please use the D1000X Utility program or the
BatSound software (versions higher than 3.31). The current GPS position data can be shown
on the D1000X display by momentarily pressing the ON/OFF key. After about 5 seconds, the
display will return to its normal view again.
The GPS position data has the format:
Latitude: (N/S) DD MM SS.SSSS
Longitude: (E/W) DDD MM SS.SSSS
D = degrees, M = minutes, S = seconds
Note: If the D1000X does not receive any GPS data from the receiver (e.g. due to poor
reception), the position data in the files may be invalid or old.
