5.3 Communication through the Local Area Network (LAN)
The TCP/IP connection, used to control the ACU, is assigned in the AxTraxNG
software’s Network Properties dialog box.
The PC running the AxTraxNG software can communicate with the ACU
through the LAN card inside the PC. The ACU connects to the LAN using
Rosslare MD-N32, TCP/IP to RS-232 gateway converter. MD-N32 can be
connected in any legal network address in the Local Area Network.
The following type of connection is used when a LAN network already exists
and therefore the long RS-485 network is not required. This schematic
illustrates the connection of a single AC-215 to the PC using the LAN network.
MD-N32 must be first configured by Rosslare's Netconfig software. The setting
is stored in a non-volatile memory in the MD-N32.

Multiple ACUs can be connected by adding an RS-485 converter (MD-14)
between the RS-485 ACUs network and MD-N32 converter.
