Ethernet connection between the DX2000 and the MW100

Q:
I want to connect the DX2000 and MW100 via Ethernet to acquire data from the MW100 onto the DX2000. Does the MW100 require the MATH function? Also, if I connect a power monitor to the DX2000, this is RS-422 communication, but I want to connect to the DX2000 via Modbus/RTU, so can I use both side-by-side?

A:
The DX2000 (client) requires the expansion channel function option (suffix code: /MC1) or the MATH function option (suffix code: /M1). The MW100 (server) does not require the MATH function. Both serial and Ethernet can be used together. In that case, the DX2000 will require the RS-422A/485 communication interface option (suffix code: /C3) and the MATH function option (suffix code: /M1).
