• Set the Comm Selector DIP Switches 6 through 8
for LonWorks Option Card
The following example shows the DIP Switches set
for 38.4k baud, Port 1and LonWorks Option Card.

5. Connect the LonWorks network to the LonWorks
Option Card's 2-pin Net port.
NOTE: The 2-pin Net port provides TP/FT-10
channel compatibility. The TP/FT-10 or "Free
Topology" network type is polarity insensitive. Use
24 to 16 AWG twisted pair wire.
6. Turn on power to control board.
Verify accuracy of the following:
• Baud rate DIP switches 1 and 2 set to 38.4 kbps
• Protocol DIP switches 6, 7, and 8
• Jumper set to EIA-485 2-wire when using the Lon-
Works Option Card
• Proper connection wiring
• Unique rotary address switches 1 – 99. If controllers
have duplicate addresses, network communication
can be lost.
NOTES:
• If RX LED is solid, then the terminations are incor-
rect.
• If the network has greater than 32 devices or
exceeds 2000' (610 m) a Repeater should be
installed.
• If a controller begins or ends a network segment,
a BT485 terminating resistor (P/N 10061018) may
be required.Touchscreen Tree
