T&T: Nmea/GPS software GpsGate 2.0

[Dave Cooper]

My last post was before my second cup of coffee!

I should have added that the ideal situation is to use a multiplexer to
combine the NMEA sentences from many devices and have them output both on a
NMEA bus that can drive 4 or 5 NMEA listeners as a minimum and also output
on USB/Firewire/Serial/Ethernet/Bluetooth ports.

With this you would then be able to configure just about any NEMA talker to
any listener whether it be a software program or a plotter/display or other
hardware user of the NMEA data.

Right now the wires we seem to have are growing exponentially. Our 8 input
USB expansion is full already and we need to get another one. I hate to plug
and unplug cables so keep as much plugged as possible. A 2 GB flash memory,
a 300 GB disk drive for charts, two different camera cables, a usb/serial
adapter for the AIS/GlobalStar data port, Delo GPS, a USB/serial adapter for
the side/forward scan sonar and the USB output of our 3 axis solid state
roll/pitch/yaw gyro.

Yipes, that's a lot of crap for one old Dell laptop, eh! We did have lots of
lockups when we started but as we worked thru them the system seldom needs a
reboot. Usually I have to reboot as I'm installing something vs. a need to
do so from a system fault.

YMMV
