I just started tinkering with M710 and tried connecting it via RS232 cable to a laptop with RS232 connection. I changed the setting according to the manual and pressed start. It would start running and transmitting but there is no response. How can I know if the radio is actually transmitting/ "talking" to the PC?

Did someone try using M710 with N3ZH? Can you guys walk me through it?

I am also trying to communicate my IC-M802 with the computer, any information will be of great help to me.

Thank you.

Hello Aiko Love del Rosario

That IC M710 DB9 Remote port is not an RS232 port. It passes Rs 422 data and modulation and Rx audio signals. You would be better off buying a USB to clone pin programming cable. Get an IC M710 manual and read topics on this group from March 17 2017 and back to the beginning that talk about HRI and the IC M710.

Good luck

Hi Charudatt

Check the topics in this group from March 17 2017 and back to the beginning.
Your IC M802 is rs232 with flow control.
I am using the Windows Visual Studios version of HRI

Good luck

You might have better luck looking at old posts on the yahoo group.

I am running the HRI Windows Visual Studio version with an IC M710. Howard N3ZH worked with the Russian guy in previous topics on this group to get the HRI Windows Visual Studio version working with the IC M802. I do not know if Howard added the needed serial port flow control in the Java version of HRI. What version of HRI are you using?

Also I am using the March 17 2017 test version of HRI Visual Studio with an IC M710.

I am not sure when Flow Control was added.
In Settings Window, Radio, there is "No Flow Control" which can be changed to "RTS/CTS" if your radio needs it.

This flow control settings appears to only be in the Visual Studios version of HRI.

No, NO flow control is added in the latest software. Unfotunately, I am just not able to get my IC-M802 to communicate with the PC. I am using a CH340G with Flow Control PCB for the control Cable.

Just wonder if there are any scheme out there to help homebrew a CAT Cable with Flow Control.
