Full diagnostic capability is provided in a serial datalink network having a plurality of control modules. Each control module includes a differential receiver for providing noise immunity and a transmitter having a positive line driver and a negative line driver. Positive and negative transmission wires connect differential receivers to the positive and negative line drivers. Circuits sense the occurrence of a short circuit condition between the positive transmission wires and ground and between the negative transmission wires and supply voltage. Overcurrents in the positive and negative transmission wires are also detected. |
