The RS-232 MicroLink HART Protocol Modem facilitates communication between HART devices and any Windows-based computer equipped with an RS-232 serial port. The MicroLink series of HART modems were designed to comply with the HART physical layer, delivering modems compatible with all certified HART devices and all leading HART configuration software that uses an RS-232 serial port for the interface. Included with each MicroLink modem is the newest version of PACTware, our Microflex Generic HART DTM-6, and a HART Protocol DTM - everything you need to connect and communicate with your device, with no configuration or setup required. Designed for rough field use, the modem is housed in a rubber and stainless steel enclosure. The modem requires no external power source, and is engineered for low power consumption to extended portable computer battery life. It comes with built in leads with transformer isolation, simplifying loop connections and eliminating grounding effects.
