TimeTools T1000 syncs your PC's clock with GPS (Addict 3D)
Here's a likely candidate for most unnecessary, albeit entirely geeky device of the day. TimeTools' T1000 Precision Time Server links up to your Windows, Linux, or Unix workstation in order to obtain "highly accurate time" from GPS satellites.
Hi guys,
I got some error on my application server mentioning that gps clock not sync to my db server.
what is the command to check is my server is sync with the gps clock?
appreciate if you guys can let me know how to troubleshoot this problem.
Thanks (1 Reply)
Hi
If you had a choice of processor for a general purpose web server, either:
A. T1, 8-core. (in a T1000, 8GB, 72GB SAS x 2)
or
B. Dual 1.6GHZ USIIIi (in a Sun Blade 2500 Silver Workstation, 4GB, 146GB SCSI)
Would A be significantly better than B?
Even on single-threaded tasks?

We have a Sun T1000 that was supposed to get used on another project. We don't think it has an os, and it does not have a cd/dvd drive. How do people normally install an os under such circumstances. Also, I need to get it hooked up to a console to see what happens on boot. (3 Replies)
GPSTRANS(1) GPS Utility GPSTRANS(1)NAME
gpstrans - communicate with Garmin GPS receiver
SYNOPOSIS
gpstrans [ options ] [ file ]
DESCRIPTION
gpstrans allows the user with a Garmin GPS receiver to upload and download waypoints, routes, almanacs (satellite orbital elements) and
trackroutes. If file is not supplied, data will be read from stdin (-ux switch) or written to stdout (-dx switch).
OPTIONS -pport set serial I/O device
-s set datum, format, offset, and device interactively, and save them in $HOME/.gpstrans.
-i identify connected GPS
-o turn off GPS device
-t get time from GPS
-ts get time from GPS and set system time on host
-dx download data indicated by x: r=route, t=track, w=waypoint, a=almanac
-m With -dt, downloads track data in the format which can be displayed by Mayko mXmap(1). With -dr or -ur, downloads or uploads route
data in a format compatible with Mayko mXmap.
-ux upload data indicated by x: r=route, t=track, w=waypoint, a=almanac
-v print program version.
--verbose
Increase verbosity.
--debug
Add debug printouts.
--help Print help text.
CONNECTION
For a DB-25 connector, you may need to connect pin 4, 5 and 6, 8, 20 together. This sets handshake signals so that your workstation can use
the serial port to communicate with the GPS.

Connect the Garmin cable as follows:
2 3 7
o o o o o o o o o o o o o
o o o o o o o o o o o o
Pin 2 goes to DATA IN (White)
Pin 3 goes to DATA OUT (Brown)
Pin 7 goes to GROUND (Black)
If it doesn't work in this way, try exchanging pins 2 and 3 at the connector.
The circular connector on a Garmin GPS II receiver can be wired to a DB-9 connector as follows:
_____ _____,-----,
3 / 4 | | |
| o o | | | |_____
| < <- groove -> |=====| |----,|
| o o | | | | ||
2 _____ / 1 |_____| | ||
`-----' ||
||
views are looking ||
into connector ||
at each end of cable ||
||
||

o o o o o | \___________||
o o o o |_________,------------'
DB-9 pin 2 goes to circular connector pin 2
DB-9 pin 3 goes to circular connector pin 4
DB-9 pin 5 goes to circular connector pin 3
other pins are not connected
(Note: the pin numbers for the circular connector are
arbitrary, and may not match the `official' numbers.)
If your plug is more recent than the one above (ex: etrex) then you need DB-9 or DB-25 to be connected to your Garmin GPS like this:
_____,-----,
POWER(+) | | |
groove --> |=====| |_____
DATA IN | | |----,|
DATA OUT | | | ||
GROUND(-) |_____| | ||
`-----' ||
||
||
||
||

||
________ ||
| \___________||
|_________,------------'
DB-25 :

o o o o o o o o o o o o o
o o o o o o o o o o o o
Pin 2 goes to DATA IN (White) Pin 3 goes to DATA OUT (Brown) Pin 7 goes to GROUND (Black)
DB-9:
5 3 2
o o o o o
o o o o
pin 2 goes to DATA IN (White)
pin 3 goes to DATA OUT (Brown)
pin 5 goes to GROUND (Black)
other pins are not connected
For testing, you might try setting the GPS to NMEA-Output and using a terminal emulator program like Kermit. The GPS will send a data
record every 2 seconds. As long as you don't see any data on your computer, gpstrans won't work.
After finishing the test, be sure to set your GPS receiver to GRMN/GRMN.
ENVIRONMENT
GPSDEV Serial I/O device (overrides contents of $HOME/.gpstrans, and is overridden by -p switch).
FILES
$HOME/.gpstrans
Has user preferences for datum, format, offset, and serial I/O device (see -s switch, above).
