address.
3. Set the Comm Selector DIP Switches 1 - 8 for
baud rate, port number, wiring, and protocol.
4. Set the Comm Selector DIP Switches 4 and 5 for
9600 bps.
Note: Use the same baud rate for all devices on the
network segment.
5. Set Comm Selector DIP Switch 3 OFF for BAS
Port
6. Set the Comm Selector DIP Switches 6 through 8
for N2.
The following example shows the DIP Switches set
for 9600 baud, Port 1, and N2.
7. Connect the communications wiring to Port 1a.
Connect to Net+, Net- and Gnd
Wiring specifications
• A dedicated 24 AWG to 18 AWG twisted pair wire
(EIA-485)
• 2000’ (610 m) for 76.8 kbps
• 3000’ (914.4 m) for 9600 bps, 19.2 or 38.4 kbps,
before needing a Repeater
• Devices should be daisy chained and not star
wired
• If the controller is at either end of a network seg-
ment, connect a terminating resistor (P/N
10061018) to the I/O Pro 812u
NOTE: Use the same polarity throughout the
network segment.
7. Turn on power to control board.
To set up the Modulating Controller for N2 on
Port 2a
1. Turn off power to control board.
2. Using the rotary switches, set the controller's
address.
3. Set the Comm Selector DIP Switches 4 and 5 for
9600 bps.
Note: Use the same baud rate for all devices on the
network segment.
4. Set Comm Selector DIP Switch 3 ON for Port 2.
5. Set the Comm Selector DIP Switches 6 through 8
for N2.
The following example shows the DIP Switches set
for 38.4 kbps baud rate, Port 1, and N2.
