MicroLink provides a simple low-cost interface between Highway Addressable Remote Transducer (HART) protocol devices and any computer with an RS-232 serial port. MicroLink was designed to comply with the HART physical layer to ensure device compatibility. A rugged design makes MicroLink an ideal choice for field service engineers and technicians who service HART devices in an industrial environment. No configuration or setup is required. Modem power is taken from the PC serial port. MicroLink is compatible with all certified HART devices and all leading HART configuration software that uses an RS-232 serial port for the interface.
