DTX1 Serial Port

Post by g0vdu » Fri May 01, 2020 6:41 pm

Can anyone assist me with the wiring of the DTX1 serial port. How is it used and is it possible to construct a interface to connect to it.
I have acquired a DTX1 and have been using it on 437 with good results. Id like to use it on 23cm (1249 MHz) so any advice would be
gratefully received. Many thanks John G0VDU QTHR

John,
The DTX1 is an excellent piece of kit. From the manual I have the following information;
Pin1 ground via 10Ohms
2 CTS
3TXD
4 RTS
5 RXD
6 DSR

Pin 1 furthest from corner of the board.
The only use that I have used the serial port for is to update the firmware. Do you have the manual? It must be online somewhere, but if not PM me and I will try and find a copy to email you with.
I believe that Laurence at Antennair will still provide support if you ask him nicely!

Laurence told me that Antennair is no more; however he has been very helpful and I have his new email address. Send me a PM if you need it.
