Author Topic: US Interface Navigator and Splitting Serial Ports  (Read 5319 times)

I have a Navigator interface and a Icom 7000.

I want to run 2 different programs that need to use the CI-V interface. It appears I need a "serial splitter" in software. The Navigator serial ports show up as hardware ports, not virtual ports. I need a program that will take the Navigator hardware serial port and make it into 2 virtual serial ports. This way I think I could share the CI-V between 2 programs

I have been googling and about all I can find is Eltima serial port splitter which I think will do the job I need.

However. It costs $100 which is too much my ham budget. Is there a lower cost solution?

I'm taking a guess, but wouldn't the serial connection be a DB9 pins 2,3,& 5?
If so could you make a CI-V to DB9 and continue to a pre made serial to USB dongle?

Or did I miss this entirely?

Two different applications controlling the same transceiver will produce collisions on the CI-V bus. If both applications fully implement the CI-V protocol's collision-detection-and-retry procedure then this won't be a problem, but there is still the possibility of one application being confused by receiving a response requested by the other application.

If one of the two applications is purely passive, meaning that it only observes the transceiver's responses without ever issuing commands of its own, then such a configuration will work if the passive application is not confused by the commands sent to the transceiver by the non-passive application.

Yes. The Navigator uses an USB connection and makes the comports in software.

Basically what I want to do is run Logic 8 logger and Fliidigi or another digital program at the same time. Both these programs want the freq (rig control) of the radio for full functionality. I think Logic 8 is passive, it just needs freq and mode for the log.

It is doable, I have downloaded Eltima's demo and it works fb. The only problem is the program is $100 and it just is not worth $100 to me. $30 or so yes, but $100 is just too much for this ham.

Paul, Thank you, Thank you. This looks like exactly what I need. I need the 64 bit version which is $25 but it is a big difference from $100.

Thanks again, I really appreciate..

UPDATE - I bought the VSPE and it works great. Exactly what I was looking for. The serial port can be shared by 4 clients. I tried it with 3 and it works fine. Very easy to setup.
