1. Connect the MultiFlex ESR to the I/O Network.

AC1 GND AC2

2. Set the network address on the first five rockers of the

dip switch (labeled S1) on the MultiFlex ESR board.

3. Set the network baud rate using rockers 6 and 7.

4. If the E2 is the beginning of all RS-485 I/O or MODBUS Networks,

NET

set all three jumpers to the UP position. For MODBUS, set the jumpers

in the top-most position (MOD). ForI/O Net, set the jumpers in the

I/O

middle position(I/O). For no termination, set the jumpers tothe DOWN position (NO).

5. Wire each stepper valve by connecting the stepper valve
