The ESH232R HART Modem provides the hardware interface between Highway Addressable Remote Transducer devices (HART) and a computer with an RS232 interface. It is developed based on a BELL202 modem standard, and is compatible with nearly all software developed for an RS232 serial port interface.
An efficient design makes the ESH232R an ideal choice for field engineers and technicians who service HART devices in an industrial environment. ESH232R is compatible with all registered HART devices and all leading HART configuration and monitoring
software that use an RS232 serial port for their interface. It is also used for a HART modem with a USB interface VSENSOR that offers the ESH232U modem.
