MicroLink-USB Specifications

101-0007

MicroLink USB includes the same HART modem used in our RS232 MicroLink (101-0005) with a USB interface to your computer.  It is common for Laptop computers to not have an RS232 serial port.  In this case a USB HART interface may be required. Typically an RS232 to USB adapter cable will not work with an RS232 modem/HART interface. HART modems use the RS232 handshake lines to control communications and handshake timing is critical for a successful HART transaction.  Our USB drivers, included with MicroLink, ensure that your HART modem will maintain compatibility with your HART software.  MicroLink conforms to FCC part 15, class B and is CE certified.
