As a guess, Yes. Yet I checked what I wrote several times, should be right.
Just what is flashing receive? I take it nothing is coming through to the PC? Does the PC need to send commands to get Mate going? From TomW post, nope.
I would try reversing the wires (2, 3) and see if it works. First. Please verify Pin 7 on Mate is negative voltage, what value? Actually all voltage readings would be good.
Have fun, Scott. [ Parent ]
checked pin 7 it is a negative 4.75 volts, I will get the other pin voltages tomorrow I also have an Easy BoB breakout box that I will stick in line to help see whats going on. don't have much light in the shop right now still wiring it up, holding a flash light is just not cutting it.
The radio modems have a transmit and receive light, the receive light is the one flashing now when the Mate is sending data to it. I have not hooked up the other modem to the PC yet. [ Parent ]
Thanks for your help, couldn't of done it out you.
It is working, hooked the other radio to the PC monitored the serial line with serialmon, I now have data to the PC from the Mate using radio modems.
What I think is a little strange, is that the transmitter hooked to the Mate has the receiving light flashing and the radio hooked to the PC has the transmit light flashing, I would think it would be the other way around.
Again thanks!!!

You are welcome!
The wires names are throwing you off.
A straight cable connects DTE to DCE, called a modem cable. Pin 2 connects to 2 and 3 to 3. Each end pin 2 has the same name yet, one trans other receives! Can be very confusing.
The Mate's modem is receiving from the Mate as the PC's modem is transmitting to the PC!! Simple:-)
I assumed you tested out the PC end but had to ask... should have worked. Glad it did. Good to keep in practice doing serial work, been too long.
