200 Setting Up the DH-485 Network
Link Coupler
You can connect an unpowered link coupler to the DH-485 network
without disrupting network activity. In addition, if an SLC 500
controller powers a link coupler that is connected to the DH-485
network, network activity will not be disrupted should the SLC 500
controller be removed from the link coupler.
