Yes, they work fine with all modules. The Signal-Master uses the same cable is the radian, but the BLD modules use a straight 3-pin connector instead of the 6-pin (the cable is supplied with the BLD modules).
We also have our own stock of the USB modules for people who buy second-hand Radians to upgrade (they were designed by CARVEC originally).
Struggling with this. Getting no response either on the default port COM4 or the correct COM10. Thought it was VMWare emulator on my Mac that might be the issue. Tried now on a PC and still no response. Tried a second Radian and unfortunately the same. Must be the Freefly USB I am using or the connections. But the lights on the USB and Radian are responding, the green solid and the amber pulsing. Either need some ideas and/ or a Carvec USB!!
