Wired controller

I’m operating my crawlers in tunnels using the old IFI Robotics controller system by hooking a 200foot DB 9 cable to the tether ports this works great but running out of parts does anyone know of a controller I can get that will offer similar PWM ports and motor control or know where I can buy more controllers?

The Sabertooth series should have similar inputs.

What are the specs for the controller? How many channels, what voltage and max current? Note that the communication protocol itself may vary.

You likely only need RC motor controllers with the right current to plug into a handheld RC wireless controller with enough channels.

thanks but i need a tethered system not wireless.
