Chapter 12 Terminal Connections
The DH-485 connectors are not electrically isolated. If electrical
isolation is required, use Link Couplers (Cat. No. 1747-AIC) as shown
on next page.
Connecting to a DH-485 Network
This section shows how to connect a DH-485 terminal to multiple SLC
controllers on a DH-485 network through the AIC Link Coupler.
ATTENTION
Electrical isolation using Link Couplers (Cat. No. 1747-AIC) is
required where the distance between the PanelView terminal
and the SLC is greater than 6.1 m (20 ft).
TIP
For PanelView 300 Micro terminals, refer to page 218.
IMPORTANT
The DH-485 network cable requires proper shielding, grounding
and termination. Refer to Data Highway / Data Highway Plus /
Data Highway-485 Cable Installation Manual, publication
1770-6.2.2).
