Check to make sure the RS-485 communication wires are properly connected. Make sure the
data conductors are not swapped. Measure the DC Voltage across D+ and D- at both the
monitoring enclosure and at the data terminals of the remote device. If the measurement is
0 DC you have a short in the data wires. If the difference between the two measurements is
greater than 3 DC then you may have an open circuit.
