DZNR-768
Description: The Delta Controls DZNR-768 is an intelligent RS-485 BACnet MS/TP, 4-port network repeater. It has two removable terminals for 2-wire twisted pair connections, and four RJ-45 jacks to accommodate the quick connect cabling used with the DZNT-VAV products. The DZNR-768 also includes 118 on-board LEDs that continuously monitor network traffic and display communication errors.
Features:
- Can be used with any BACnet MS/TP Network
- Divides a network into smaller segments for easy troubleshooting
- Supports twisted pair and Delta Controls CAT-5 MS/TP wiring
- Uses autobaud detection, removing the need for manual configuration
- Shows the online or offline status of each controller
- Built-in capability protects against controllers up the network
- Displays the status of individual network segments
- Identifies controllers with duplicate addresses
- Detects unreliable character transmissions
- Identifies network wiring faults
Application: The Delta Controls DZNR-768 divides a single network into four separate segments allowing a maximum of up to 50 controllers on any given segment. It improves the signal quality on each segment. The built-in diagnostics provide checks for the condition of each controller as well as the general condition of the communications on each segment.
Segment 1 typically connects to a System Controller and the three additional segments allow for distribution of the other network controllers. Combined segments allow for a total of 99 controllers per DZNR network.
The network cable length for each segment is 4000 feet (1200 meters) for twisted pair and 2000 feet (600 meters) using the CAT-5 MS/TP connections.
