This is another Omnex Industrial Radio Control system, used on a concrete pumping truck. It controls everything... the articulated boom, concrete rate, engine speed, etc. This one took an unscheduled bath in concrete. The operator didn't realize that the very acidic concrete / water slurry got inside. Unfortunately, this damaged connectors, a few components, and ate several pcb traces right off the board. I replaced a few components, patched the board, and got it back online.
