DH-485/DH+/Remote I/O
Module
PanelView Plus terminals with a DH-485/DH+/Remote I/O
Communication Module supports communication with the following
networks:
• DH+ networks
• DH-485 networks
• Remote I/O networks
You can communicate with only one network at one time.
The PanelView Plus 700-1500 terminals support all protocols on one
module. The PanelView Plus 400 and 600 terminals require a separate
module for each protocol. The DH+, DH-485 and Remote I/O
connections are different between the modules for the PanelView Plus
400-600 and 700-1500 terminals.

TIP
The DH-485/DH+/Remote I/O Module (700-1500 only) is
supplied with 2 ferrites for cables. After installing the
communications cable, place the ferrite around the cable
close to the Module Connector. The ferrites suppress EMI
(Electromagnetic Interference) from the cable.
