The LDA Series Radio Remote Control System provides the flexibility to be configured as either a 900 MHz or 2.4 GHz system.The Transmitter features 20 digital channels, and 8 analog functions. The Receiver features 16 discrete solid state outputs (8 of which can be configured as analog PWM outputs), LED feed back and a J1939 CAN (Controller Area Network) connection. With internal processing capabilities, these robust industrial remote control systems can be programmed to fit any application.

End of an Era...
Well, he did it, Tom Herman decided to hang up his tools and venture into the world of retirement. His send off was Wednesday, June 25th 2008. It was held at "The Pines" golf course club house just up the road from the shop.
