ABSTRACT:
A voltage level conditioning transceiver cable includes a a voltage level conditioning circuit, a single ended to differential circuit, a controller connector, a device connector, and a plurality of lines. The voltage level conditioning circuit and the single ended to differential circuit are mounted on a circuit board. The controller connector is attached to one end of the circuit board. One end of a plurality of lines are attached to the other end of the circuit board such that they are disposed substantially parallel to a front of the controller connector. At least one light indication device is attached to the circuit board, such that the light indication device emits light when there is a data transfer between the programmable controller and another device. The circuit board is molded over with the controller connector and plurality of lines. The other end of the plurality of lines are connected to the device connector. The other end of the plurality of lines are molded over with the device connector.
