RS-485 Network Test

Figure 31: RS-485 Test

The Configuration Software has an RS-485 test program.

Although it uses Modbus settings, it is testing RS-485 communication.

The test requires connection to a COM port using the Data Industrial A302-20 RS 485 to RS-232 convertor cable. This cable can

also be helpful with other diagnostics programs and devices that use an RS-232 port to communicate.

When testing the RS-485 network, it is sometimes helpful to connect to some other location instead of directly to the 340

BN/MB Btu Energy Transmitter. When testing in this way the RS-485 end connector can be removed, and the wires can be

connected directly to the RS-485 pairs.

The following table may be helpful to make connections.
