Question about Magellan eXplorist 500 GPS Receiver
Problem is with NMEA communication from Explorist 500 to OziExplorer ( or Hyperterminal). Equipment: (Dell Inspiron 1100 with Windows XP - Explorist 500)
Windows New Hardware Wizard shows appropriate dirver is oem45.inf for NMEA mode, and another oem65.inf is presumably for USB mode ( I haven't checked this).
-Menu/Adv.Features/Communications/NMEA Data Com/V2.1GSA/NMEA->COM
-"secret" menu 40 check baudrate 4800 -startup, find satellites and locate position
-plug in to computer USB (with cable right way round, tail downward!) -check with Windows Control Panel/system/hardware/device manager: Explorist on COM7
-also tried simulate mode on Explorist, simulated trace appearing on local map
OziExplorer (build 3.95.4q) configuration:
-GPS : Magellan USB -COM: COM7, 1 stop bit, no parity, NMEA baudrate 4800, Serial Driver 2
-Upon starting Moving Map NMEA start I get no error message, in contrast to case of disconnection or wrong COM port.
-Moving Map/ Show GPS Fix or Show NMEA In window Input and Output boxes remain blank.
Hyperterminal on COM7: -nothing.
-shows no NMEA message on any port, including COM7
I conclude that various software under Windows recognise Explorist connection but see no NMEA messages. In file transfer mode, the Explorist appears and works correctly as an external drive. I read that NMEA protocol does not use handshake, so assume that Explorist should not wait for appropriate trigger before sending NMEA position sentences but I have tried moving GPS around or simulating movement in case it only reports changes... still no signal. I have tried Explorist 500's Menu/ Clear Memory to try and get a fresh start. I assume for now that the problem is with the Explorist or the Windows drivers, can anyone suggest a method of restarting from scratch to get it going?
Try rebooting windows, with gps off connect the cable to gps.
Go out side get a good gps signals on nav menu.
Set the gps communications menu to , nmea, 2.1
Plug the device into a good usb port.
If you look under modems, in control panel you should see a new modem called explorist xxx
If you look at the properties for that you can see its com port number.
I just tried this program http://www.visualgps.net/VisualGPS/
and it views nmea from the explorist, just set the com port to the one in the explorist modem .
