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.
