A stab in the dark. I don't have one of these.
The doc I find says that these are supplied with a rechargable lithium cell
which enables back up of GPS data . It is supposed to last 10yrs, so if
yours is reaching retirement age it may have gone awol and dropped the
serial parameters to a state which your monitor is not set too.
So you could try all the baud rates listed in the specs. Use a terminal
emulator instead of the monitor program, which appears to be a graphic app,
to see if you getting any data output .
default appears to be 9600,8 bit,no parity
Serial Interfaces
a.. Port 1: True RS-232 output, asynchronous serial input compatible with
RS-232 or TTL voltage levels, RS-232 polarity
b.. Port 2: Asynchronous serial input only, compatible with RS-232 or TTL
voltage levels, RS-232 polarity
c.. Baud Rates
d.. 300/600/1200/2400/4800/9600/19200
e..
Serial Formats

Subject: [time-nuts] Garmin GPS17
Hello all,
I have a Garmin GPS17 HVS which is a GPS receiver/antenna in one unit.
When I first bought it I used it to discipline an HP10811 OCXO. One day
it stopped
responding to its monitor program.
I got a TBOLT which has kept me busy and now I want to compare it to the
Garmin.
Although I used to be able to run the monitor program and it does not
respond any more,
if you put it under the sky and power it up, after a while you get a PPS
out of it that is
in phase with the GPS.
So there is somebody home but they have turned out the lights.
The Garmin manuals mention failure to respond if you do the wrong thing,
Can anyone help me get it going again?
Cheers,
Neville Michie
