[Elecraft] KX3+KXPA100+PX3 = Outta Inputs/Outputs

[Dick Dievendorff]

RS-232 is not a multipoint protocol.

Dick, interesting. I wonder if anyone has used the USB hub idea to make a multiple port daisy-chained ACC1 interface? So can ACC1 be hubbed? Could I create multiple ports from the KX3 ACC1 combining the PX3, the KXPA100, and my Mac running radio control software? Anyone done that with the KX3 Line?

I'm using a Gearmo 4-port USB to Serial adapter ( <http://www.amazon.com/GearMo%C2%AE-36inch-Windows-Certified-Drivers/dp/B004ETDC8K/ref=sr_1_1?ie=UTF8&qid=1420241893&sr=8-1&keywords=gearmo+4-port+usb+to+serial+adapter> http://www.amazon.com/GearMo%C2%AE-36inch-Windows-Certified-Drivers/dp/B004ETDC8K/ref=sr_1_1?ie=UTF8&qid=1420241893&sr=8-1&keywords=gearmo+4-port+usb+to+serial+adapter)

And I've also acquired an 8-port Edgeport from an eBay vendor.

I use a number of KXSER cables for the DE-9 to 3.5 mm transition. I do test software with a KXUSB, but its FTDI chip set seems equivalent to the Gearmo 4-port adapter.

One serial port is used for KX3 + PX3 + KXPA100 , they daisy-chain.

One serial port is used for a K3 - P3 daisy chain.

One is used for KAT500

One is used for KPA500

One is used for a W2 or LP-100A (telepost) or XG3. I don't tend to use all of these at once.

I used to use some ABCD DE-9 switches, but prefer to have them all connected and it's easier to pick the combinations I need at once.

There is also the USB hub solution, one hub on your PC might fan out to 4 or 8 USB ports.

Thanks Gil. I have plentiful Mac USB physical ports (about 8). So the issue is with the KX3. Got no place to plug it in. :—(

Sounds like you need a virtual serial port emulator program.

Got the KX3 Line. KAT500 and W2 also. Love ‘em. Now, I appear to be out of inputs and outputs with little lines running between the boxes and all of the inputs/outputs in use. What do you do to get a KXUSB into the KX3 for radio control from a variety of software programs into an ACC1 PC port? None available. Can the ACC1 port be Y’d?
