– pull off function. This connector should be pushed into position with the flat sprung loaded surround (which displays an arrow) to the base of the 3000LRS unit. 2. Connecting the Antenna cable The antenna cable supplied with the unit is terminated with a TNC type connector.
3000LRS DGPS RECEIVER OPERATOR’S MANUAL Boot up Sequence On initial power on screen displays: Model name and type Firmware version The unit’s serial number will then be indicated The unit will now search for an uplink Unit locks onto uplink signal.
If when powering on your 3000LRS unit with the antenna connected the unit does not advance passed the ‘synchronising’ mode in the Boot Up Sequence, then confirm that the unit is operating on the correct satellite channel.

These RTCM corrections enable the GPS receiver to compute a differential corrected position. The Seastar receiver uses the AUX port to send RTCM to, and receive NMEA from, the external GPS receiver. The AUX port can only handle RS232 data.

3000LRS DGPS RECEIVER OPERATOR’S MANUAL Model 3000LR8S or LR12S This model contains an internal 8 or 12 channel GPS receiver and will operate without connection to an external GPS position. With the internal position input a composite set of RTCM corrections is computed from the GPS network data sent over the link.

Q-Why does the Seastar receiver require a position input from my GPS receiver? A-If the Seastar receiver receives a position input from the GPS receiver it can then compute optimised RTCM corrections for the present location which will improve the accuracy of the system.

3000LRS DGPS RECEIVER OPERATOR’S MANUAL Q-Which port on the Seastar receiver do I use to connect to my GPS receiver? A-Always use the Auxiliary (AUX) port to connect the Seastar receiver to a external GPS receiver Q-What can I use the DATA port for? A-The DATA port echoes the AUX NMEA input from the external GPS receiver.
Page 29
A-Often it’s the case that GPS receivers using RS422 use different ports to receive RTCM and transmit NMEA. The port to receive RTCM from the Seastar receiver is normally a RS232 port; the port to transmit NMEA to the Seastar receiver could be a RS422 port. Connect the RS232/422 converter as follows:...

3000LRS DGPS RECEIVER OPERATOR’S MANUAL Some GPS receivers use only one port for input and output. If this port can only handle RS422 then connect it up as follows: Seastar RS232/422 converter AUX Port RS232 side RS422 side Receiver Pin 2-Rx NMEA...
