ok, new small project...
STEPPIR SDA-100 or SDA-2000 users...
The remote control port (DATA OUT) or Radio interface ports (DATA IN) can not be connected directly to an RS232 cable, because the DB9 connectors for both the DATA IN and DATA OUT are NOT using the standard pinout, thus you HAVE to use an adapter... Here it is.
Our small project offers the possible conversion from CIV to STEPPIR for the DATA IN port using a 3.5mm CIV connector and a Female DB9 port.
It can also be made to be a normal DB9 Male to DB9 Female with proper pin conversion,
Or, finally, it can also be used as a DB9 Female-to-DB9 Female again by using proper DB9 connectors and changing the jumpers.
Finally, you can have DB9 and CIV connectors installed to switch from DB9 radios to CIV by simply changing the configuration in your STEPPIR SDA Controller!
I will be making 20 PCBs; they are easy to assemble. Once you get the PCB, you will also have links to Amazon or AliExpress for the required parts.
The Ge**er files and plans will be offered on the WWW.VE2DX.COM website...
I will ship to Canada/USA for 25us$, DX 30us$... these are simply to pay for the new web page coming around the end of summer, this is a great example of the type of projects that will be publish on the new website... Simple lowcost, DYI... when PCBs are offered they will be to help us keep the website affloat.
