Communication Test
Step 1 : Connect PC, HRT-310 and HART slave device according
to figure1.
Step 2 : Set the DIP switch of the “Default” to be “ON” position.
Step 3 : Turn on the power of HRT-310.
Step 4 : Wait for the “RUN” LED to be always on status. If the “RUN” LED
always flashes, it means the HRT-310 can’t communicate with
the HART device. Please check the HART network wiring.
Step 5 : Execute the HG_Tool utility.
Step 6 : Set the communication settings between PC and HRT-310.
When the DIP switch of the “Default” to be “ON” position, the HRT-310
will adopt the below comport communication settings.
[1] Protocol: MB RTU
[2] Net ID: 1
[3] Baud Rate: 115200 bps
[4] Data Bits: 8
[5[ Stop Bits: 1
[6] Parity: None
=> So the HG_Tool must have the same settings with the HRT-310 as
shown in the below figure.
