<div><strong><font size="2">Could someone sort out a technical detail
for me. I am attaching a GPS35-HV to a Kenwood D700A. The GPS35 has a
cigar lighter power connector and a DB9 RS232 connector as standard
equipment. </font></strong></div>
<div><strong></strong> </div>
<div><strong><font size="2">The diagram in the D700A Specialized
Communications Instruction Manual has a diagram on page 10 which shows
the 3 conductor plug with pigtail to GPS wiring. I want to make up a
DB9 connector on the end of the plug's pigtail. The diagram says the
white lead goes to the GPS DATA IN, the red lead goes to the GPS DATA
OUT and the shield goes to GPS GND. I understand that the three pins
on the DB9 I need to connect to are 2, 3 and 5. Shield goes to 5.
Which pigtail lead goes to 2 and which goes to 3. Pin 2 is normally
called RXD and pin 3 is normally called TXD. I am always confused by
this. Just tell me red => 2, white => 3 or whatever. I am not
smart enough to go beyond that.</font></strong></div>

Just wire it one way or the other. You have a 50/50 chance of it
working on the first try. Nothing will be damaged if 2 and 3 are
reversed. If it doesn't work, just transpose the wiring on pins 3 and
2. <br>
