ABSTRACT:
A programmable device driver and system thereof are provided for segregating functions and hardware in a railway signaling environment. The device driver includes a central processor with a memory and a timebase which is programmable to perform a function. The central processor may be detachable from the device driver. The central processor may be encapsulated in resin or potted to provide resistance to the environment. The device driver may be provided with voltage and current sensing inputs, a power input connected to a power conditioning circuit, one or more outputs, a conditional power supply, and mounting brackets. Each input may be provided with surge protection. The device driver may be provided with terminals for the inputs and outputs or pigtail leads for increased moisture resistance. The device driver also may be provided with a serial port for communicating with other programmable device drivers, a multifunction central processor, or other external device. The system includes multiple programmable device drivers, each one programmed to perform a certain function. Each device driver may be provided with a serial port and interconnected to form a local area network. The LAN may be additionally connected to a multifunction processor for remote control and monitoring.
