Network layout
The DZNR accommodates both twisted pair and Cat5 wiring methods for Rs-485 MS/TP
networks. Each of the DZNR’s four ports divides the network into individual segments. On each
port you can select either the twisted pair or Cat5 media. Use only one or the other wiring
methods on each port. Do not connect both the twisted pair and Cat5 types to the same port.
Hardware revisions prior to 1.2 support Cat5 only on ports 3 and 4.
The Delta MS/TP Cat5 or higher (Cat5e, Cat6, etc) cabling technique allows quick, error-free
connections across the controllers on the MS/TP segment. Applying Delta’s ADP45-MSTP
family of Cat5 accessories further expands wiring options.
The network system controller is placed on Port 1 and is assigned a network MAC address of 0.
Ports 2, 3 and 4 are used to interconnect the remaining controllers.
No more than 64 controllers can be connected to any one segment and no more than 99 total
controllers are recommended per DZNR.
Wiring and data wires termination must conform to the recommendations in Delta Controls
Installation and Wiring Guidelines for wire length, shielding and grounding for each wiring
segment.
