b. Connect the 1203-USB converter 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.
2. Using a 22-RJ45CBL-Cxx communications cable, or an appropriate
twisted pair cable with two connectors ( Figure 3.2 ) from an
AK-U0-RJ45-TB2P kit, insert the connector from one end of the cable
into the splitter cable Slave port (identified by the letter ‘S’ at the port).
3. Insert the connector on the other end of the cable into Port 2 on the
bottom of the second drive (Drive 2).
Figure 3.1 Wiring Example for RTU Master Network
For all subsequent DSI drives—up to 32 drives total on the RTU Master
network—daisy chain them together using the same method, type of cable,
and terminal connectors connected into Port 2 on the bottom of each
respective drive.
The AK-U0-RJ45-TB2P kit contains 6 two-position terminal block
connectors (
Figure 3.2 ). These connectors can be used to conveniently daisy
chain the DSI drives from Drive 1, which is connected to the 1203-USB
converter. Two terminating resistors are also included with the
AK-U0-RJ45-TB2P kit and must be used on the connection to the first and
last drives on the network.

Figure 3.3 shows a wiring diagram for using AK-U0-RJ45-TB2P terminal
block connectors and the two terminating resistors.
