Communication
Switchable between selection of preset or user-defined settings.

Default preset-settings: HART protocol over Bell 202, on the primary mA output, 1200 baud; Modbus protocol in RTU mode, on the RS-485 output, 9600 baud; 1 stop bit, odd parity.

Default user-defined settings: HART protocol, on the RS-485 output, 1200 baud, 1 stop bit, odd parity.

Bell 202 signal is superimposed on primary variable mA output, and is available for host system interface. Frequency 1.2 and 2.2 kHz, amplitude 0.8 V peak-to-peak, 1200 baud. Requires 250 to 1000 ohms load resistance.

RS-485 signal is a ±5 V square wave referenced to transmitter ground.

Baud rates between 1200 baud and 38.4 kilobaud can be selected.
