I am not wanting to get involved but I actually went thru this already.
The way I understood it and how we gather it is thusly:
Mate tosses the data on the serial port approximately every 60 seconds. I only am interested in gathering the data not sending commands.
You power the Mate side of the port with DTR if i recall right. I will check before i hit submit.
OK, checked my notes probably copied from the same PDF you have:
The Mate requires that the DTR (pin 4) be driven high(set) and that RTS (pin 7) be driven low (cleared), in order to power the port.
The Mate transmits data on the RX (pin 2) line,and listens for commands on the TX (pin 3) line.
Probably the same thing you read.
No real communication [on mine] just power the port read the data. At least with my system. No reason you couldn't just hardwire those pins high and low that I can see. We did it in software, however. I had lots of RossW and DonC help as well as others who I forget now.
Be sure its a straight through cable, too. Got caught trying to use a null modem cable by accident myself.
Just tossing it on the pile.
