No, the serial ports on the HART Test System are designated for specific purposes and cannot be used interchangeably.


Serial port 0 is used for communication between the HART Master and the device via a registered RS-232 HART modem, and Serial port 1 is used by HSniffer to capture data on the FSK bus via a registered RS-232 HART modem when the HART Master and the device are communicating.


On Test Systems shipped after August 2015: 

- Serial port 0 (for HART Master) is the serial port labeled RS232-0.

- Serial port 1 (for HSniffer) is the serial port labeled RS232-1.


On Test Systems shipped earlier:

- Serial port 0 (for HART Master) is the serial port labeled RS232.

- Serial port 1 (for HSniffer) is the serial port with no label.


Without a registered RS-232 HART modem connected between Serial port 0 and the device, there can be no successful communication between the HART Master and the device.
