That depends. If you're looking at the _pins_ in the position you show (5 on the bottom) then it is the 2nd and 3rd from the right on the bottom row.
If you're looking at the _holes_ then it's the 2nd and 3rd from the left. If you look very closely with a magnifying glass you'll probably find that the pins and sockets are actually numbered in the connector. ----- Original Message ----- From: Thomas Morehouse To: [email protected] Sent: Friday, April 05, 2019 3:49 PM Subject: Re: [M100] TeraTerm - still not communicating Twenty-seven messages in this thread, plus my two previous threads, and I've received lots of good info. But I'm more lost than ever. For the "loopback adapter", what pins am I trying to connect? In other words, looking at the external pins on the 102 serial port: o o o o o o o o o which two of those nine pins am I supposed to be connecting? (This seems to be a bit more thorny and problematic than I'd expect.) Tom M. On Fri, Apr 5, 2019 at 3:40 PM John R.

Thomas if you want to prove out your cabling without buying a new USB adapter you will need to come up with a way to rig up a loopback adapter. If the device can send a byte and receive it back over the loopback, then it is good enough for what you are trying to do. There is more than one way to do this, but you need to prove out the transmit and receive lines on your adapter, and on the model T. -- John.
