The ESH232U HART Modem provides the hardware interface between Highway Addressable Remote Transducer devices (HART) and a computer with a USB interface. It is developed based on BELL202 modem standards. The USB driver makes it compatible with most software developed for an RS232 serial port interface, as it appears as an RS232 port to the HART software. The efficient design makes the ESH232U an ideal choice for field engineers and technicians who service HART devices in industrial environments, and it is compatible with all registered HART devices and leading configuration and monitoring software that uses RS232 serial ports for an interface.
For a HART modem with a 9-pin RS232 interface, VSENSOR offers the ESH232R modem.
