1.Connect board to the RS485 I/O Network.

2. Set the network address on the first five rockers of dip switch S3 for the 16AI, and S4 for the 8RO sections of the MultiFlex.

3. Set the network address on rockers 6-8 on S4 for the 4AO or 8DO sections of the MultiFlex if applicable (88AO and 168AO have a 4AO section). The 168DO has an 8DO section.

4. Set the network baud rate using rockers 6 and 7 of dip switch S3. For 9600 baud, set #6 UP and #7 DOWN.

For 19200 baud, set #6 DOWN and #7 UP.

5. Set RS485 termination jumpers OUT (term) if at either end of a daisy chain. Otherwise, set jumpers IN (no term).

6. If replacing an old 8IO or 16AI, use MultiFlex input

adapters (P/N 335-2301) to plug input connectors from old board into the MultiFlex input sockets. One for inputs 1-4,

and one for inputs 5-8. Otherwise, polarity-sensitive inputs will have to be rewired. (No adapter is needed for inputs 9-16.)

7.Connect board to power transformer. If a center tap is present, DO NOT use the center tap! Instead, connect 0V terminal to a separate Earth ground.
