DIY: Simple PSP-GPS hookup

[A Fn NOOB]

BINGO! I *think* one of Deniska's wiring diagrams on his site might be wrong: I reversed the wires (GPS TXD > PSP pin *2* -- listed as GND, I believe maybe RX and GPS GND > PSP pin *6* -- listed as RX, I belive maybe GND?)

Either that, or the Garmin spec is wrong >< (i *was* getting - voltage when using my multi in a way i thought should give + voltage)

Yeah, thats what I was trying to say about some mfgr's referencing the pins with regard to what they connect to, vs their actual function...

i just got done making my cable and started gps viewer. it tells me to "Connect your GPS to seral port and turn it on" so i did but i still see this screen telling me to plug it in and turn in on. what am i supposed to do next? or does this mean the cable isnt put together right? also when i run mapthis it acts like its not connected

[deniska]

there might be some problem with the cable...
scan this thread for additional clues (it has yet another, simpler viewer app attached)

Has anyone delt with and has a diagram for Delorme Earthmate GPS?

[deniska]

Someone confirmed that Holux gpslim 240 works fine (same setup as gpslim 236)

GPSlim 240 is half the size of 236 with ~ same spec.
The retail price is ~95 USD

Don't think so..
which model do you have?
does it use serial port? at what baud?
NMEA support?
Delorme does not seem to list the comm specs on their site...

I have the model number 9538 V1.0
It has a USB. dont know about NMEA support.
Here is a link about the pinouts for this device but i am not too sure about it...

If you scroll down a bit you can see the pinouts of the USB GPS... Hope this helps a bit.

USB is no good ...
You need a serial cable option...
If you have one, use GND & TXD for PSP connection.
You'll also need to wire it to external power source if your unit does not have built in battery...

This is what the pinout looks like from the GPS:
1 - GND
2 - USB Data+
3 - USB Data-
4 - +5V
5 - RS232 RXD
6 - RS232 TXD
7 - RS232 DTR
8 - +5v
9 - GND
10 -
11 -
12 - SHIELD
The ones in BOLD are the ones that are going to the USB. So to sum it up, you are trying to say to connect Pin 6 from the GPS to the PSP and Pin 1 or 9 or both? from GPS to the PSP and then hook up an external power source to pin 4 or 8 or both? The GPS gets its power normally from the laptop with pin 1 and 4 since it hooks up to the usb. So i am assuming to hook up the power to those wires and then the GND from pin 1 to the PSP also...
