Need help? If an error message appears:
• Verify the Modbus address of the transmitter.
• Ensure that you have specified the correct COM port.
• Check the physical connection between the PC and the transmitter.
• Increase or decrease resistance.
• For long-distance communication, or if noise from an external source interferes with the
signal, install 120-Ω ½-W terminating resistors in parallel with the output at both ends of
the communication segment.
• Ensure that there is no concurrent Modbus communication to the transmitter.
