Icom 9700 In External Terminal Mode

Using the new Icom IC-9700 in DV terminal mode with the new beta version of Pi-Star 4.0 RC4 running on a Raspberry Pi for D-Star.

With version 4.0 of Pi-Star (as of Jan 25, 2019 in beta RC3) it is possible to use pi-star and an Icom IC-9700 in DV terminal mode as a D-Star node with Pi-Star as the controller/gateway. (This also will work with an Icom 4100 and an ID-51a Plus 2). You will need the following:

ID-51A Terminal Mode
IC-9700 Radio in External D-Star Terminal Mode

The Icom OPC-2350LU cable kit is used to hook the IC-9700 to the Raspberry Pi via its USB port using the DATA JACK on the back of the IC-9700 – NO USB ports on the IC-9700 are used. (My ID-51A Plus 2 came with the cable kit) Using Pi-Star ver 4.0 (currently in beta RC3 as of Jan 25, 2019) you can configure Pi-Star in D-Star repeater mode. It is important to select Controller Software Under the Control Software section as DStarRepeater after you have hooked the pi to 9700 via the OPC cable kit – then reboot, then under General Configuration select the Radio/Modem Type as Icom Radio in Terminal Mode (DStarRepeater Only) and finish configuring pi-star, my Pi-Star config looks like:

In order for pi-star to “see” the Icom IC-9700 in terminal mode via the OPC-2350LU adapter/cable you will need make sure that the USB Function under the DV DATA setting from the Connector main menu is set to DV Data. Then to put the IC-9700 in DV terminal mode; Get into the menu settings and under the DV GW tile make sure Gateway Select is in External Gateway (DATA) mode and then select <<Terminal Mode>> :

Here is a short video showing how to get into Terminal mode with an Icom IC-9700 and PiStar:

At this point, via a web browser, web into the pi-star dashboard (http://pi-star.local. providing you have set up pi-star on Raspberry Pi) you can link and unlink D-Star reflectors and repeaters – using the IC-9700 as your mic and speaker – in Terminal mode there is NO RF to/from the IC-9700.

Details on the required USB cable kit from Icom – this is the cable kit that plugs into the DATA Jack on the IC-9700 and a USB port on the Raspberry Pi (my cable kit came with my ID-51a2+):
