NOTES This product conforms to BACnet Application Specific Controller (B-ASC).
This product is designed for multiple master network, therefore 2-wire type connection is
supported.
● Node with network bias resistors
This product is a node with local bias resistors. Therefore at least one node must be a node with
network bias resistors in the network configuration.
When configuring the network with only this products, refer to the following figure, and make the
node with network bias resistors. (When using two sets in one segment, insert them into both
end of the network.)
