It would be a good idea to print out the auction page, because this contains 
the pin out of the receiver. The module has two rows of pins, the pin with 
the square pad is pin 1. The pins are numered as follows:

 1  2
 3  4
 5  6
 7  8
 9  10
11  12
13  14
15  16
17  18
19  20


The module is already RS-232 ready, no need for a lever converter chip
(MAX-232). For a serial connection to your PC all you need to do is apply
power(+5vdc) and wire TX,RX, and ground to you PC. Once powered up the
receiver will output NMEA at 4800,8,n,1. If you want to you can add a
battery backup (3.6vdc) there is a pin for this. This will allow the
receiver to lock onto a signal within 10 seconds. On first power up don't
expect a lock for about 90 to 120 seconds.
