Hi guys. Ive just bought the above and i cant seem to get it to work. I have a VIA EPIA ML6000EA with a serial port (rs-232, 9 pin d-sub, male). The GPS unit i have bought has a female ps/2 port. Ive connected these using a ps/2 to rs-232. It doesnt work at all, no led's light, it doesnt show on my com port in device manager and the program supplied on cd scans the COM ports and finds "NO DEVICE".
What am i doing wrong?
Will i have to buy a ps/2 to usb converter? as the cd has the usb drivers
The reason no LEDs lit up is because, when using a serial port for your GPS receiver, there is usually a cable that splits to a ps/2 and a serial port. The receiver connects to the PC through the serial port and receives power through the ps/2 port.
Thus, your PC is not recognizing the receiver because it has no power. You'll need either what I mentioned above or, like you said, a ps/2 to usb converter since it can connect and draw power through the usb port.
Strange that your receiver didn't come with the proper connector, though...
well, after spending an hour with a soldering iron and a multimeter i failed to get it to work.
i was following this diagram:
Ive connected everything correctly i think. its just i dont know what to do on the rs232 end of the cable. does the serial port only need information from two pins (2 and 3)? what is the need in the rest of the pins? e.g. 1,4,5,6,7,8,9
Make sure all the cables are connected to the corresponding port on either end using the following links as guides to the pinout diagrams.
PS/2 -> Serial (9 pin)
from there ive connected pins 2 and 3 to the correct pins on the gps mouse, 4 and 5. Ive then connected pins 1 and 2 of the min-din end to +5v and ground. What else do i need to do?
The serial port needs a connection to ground at pin 5.
Also, check out the last link, the last row in the table on the page.
Would anyone be kind enough to tell me what pins of the rs232 goto which pins of the ps/2 port
1 = +5V (from floppy)
2 = GROUND
3 = ?????
4 = RECEIVE (PIN 2 of rs232)
5 = TRANSMIT (PIN 3 of rs232)
6 = ?????
What do i do?!
bump again. My entire project is on the hold until this is sorted
