The digital communications parameters control how the transmitter will communicate using digital
communications.
The 9739 MVD supports the following types of digital communications:
• HART/Bell 202 over the primary mA terminals
• HART/RS-485 over the RS-485 terminals
• Modbus/RS-485 over the RS-485 terminals
• Modbus RTU via the service port
Note
The service port responds automatically to a wide range of connection requests. It is not configurable.
Important
The service port clips on the user interface of the 9739 MVD transmitter are directly connected to
RS-485 terminals (26 and 27). If you wire the transmitter for RS-485 digital communications, you cannot
use the service port clips for communication with the transmitter.
