has anyone here try with Holux GR213 (mouse GPS receiver) yet? i have all the diagram, but still cant connect anything.. it was like halfly give up already... please help me
You'll have to be more specific and detailed if you want people to help you...
Things like: which cables/ conectors did you use, how you powered the unit, which program did you use for testing, etc...
it is very important that u have the data sheet.. there are important things about the pinout.
u will need to use the output wire from the gps. there should be only one.
this is a diagram of the pinout

relying on that scribble i think you have to solder the 1st pin to the psp's rx pin.. correct me if i'm wrong deniska :/
only thing you have to determine is the output voltage and calculate the resistor you will have to use.
the gps will send nmea sentences to the psp.
these sentences are supported by mapthis.
hi,
im sorry about the detail... that is the pinout i meant (thanx lewbacca)... actually the device works fine when the indicator steady for a moment and then blinking state that the position is fixed... im using mapthis V0.2 and change the baudrate to 4800, with no UMD in the compartment and wifi off... and also the fakefeed set to 0... even i try the GPSlim236 Eboot also cant receive any info on lat and long that im on...
the diagram is like this...
pin 1 (GPS) -> 1k -> pin RX (PSP)
pin 4 (GPS) --------> pin ground (PSP)
pin 5 (GPS) --------> +5V (dc adapter)
ground (GPS)** -----> ground (dc adapter)
** note that this is not the same ground wire as pin 4, this is another ground wire from within the cable..
am i doing something wrong here? or anything should i do to make it works?
u dont need to change the boudrate. afaik the device works at the set boudrate too..
hi,
i did try with 38400 before... but still... dont know what else should i do...
did you test the wires with a multimeter?
yes... the voltage is around 0 to 5 volt jumping up and down... but most of the time is 3 to 4 volts...
i got negative voltage from the TX (GPS)... is that normal?
Did you try it with "green screen" program?
If not, you probably want to start with it, before you move to MapThis (in case of unconfirmed connection/data)
I think there is a 4800baud compiled binary for it somethere in these threads..
deniska... there was 2 pins for RX, RS232 and TTL, which one is the best to tap on?
deniska, would u mind if i send u the unit and u test that out?
From the diagram, posted above, should not you connect pin2 (not 5) to +5V dc adapter?Quote:

in case pin 1 does not work...
Sorry, but I really have no time for this now....Quote:
