Network Wiring

When wiring an RTU Master network, refer to the network wiring example shown in
Figure D.2. Connect the first MDI Class drive (Drive 1) on the network to the
1203-USB converter using an AK-U0-RJ45-SC1 splitter cable. Connect its male end
into Port 2 on the bottom of the drive. The 1203-USB converter must be connected to
the Master port (identified by the letter "M" at the port) of the splitter cable.
Important: Only one splitter cable can be used on the network, and it must be used to
connect the 1203-USB converter to the first drive.
