With the release of an updated controller in 2021 Q4 for the SPEEDCHECK-15 and SPEEDCHECK-18 radar speed signs we have also released an updated version of the serial cable used for remote connectivity with Applied Information. If you have received a new controller and have an existing configuration that utilizes the 10-pin serial cable you may need to replace the cable for the updated version.
