4-16 ADS Model 4000 Manual
Using the Direct Modem (DMI) Cable
Communicating with the monitor on site requires the direct modem
interface (DMI) cable and a field computer running the FieldScan

software. Equipped with an inline modem, the DMI cable provides
direct communication between the user and the monitor without the
need of telemetry.
To use the DMI cable for performing on-site communication,
connect the cable's DB-9 connector to the field computer's serial
communication port and the other end to the monitor's
communication port. Refer to the Direct Modem Interface (DMI)
Operating Instructions (#3506AI0050) and the FieldScan User's
Guide (#950021**) for detailed information concerning power
options and serial port assignment in FieldScan.
