Product description
The DZNR-768 (Delta Zone Network Repeater-768) is a four-port repeater that extends the
number of devices on a BACnet RS-485 MS/TP network and improves the signal quality on the
network.
The DZNR-768 divides a network into four segments allowing a maximum of 64 devices per
segment and a total of 99 devices per network.
Each segment can accommodate either the quick-connect MS/TP RJ-45 cabling used on the
DZNT-VAV product or standard MS/TP 2 WIRE cabling.
The DZNR-768 continuously monitors network traffic and uses its built-in diagnostics and
LEDs to provide a quick view of the status of every connected device. 17 general status LEDs
and 101 individual device LEDs allow you to diagnosis and troubleshoot network problems
visually.
This document describes the Revision 1.2 DZNR-768 which was released in 2013. Throughout
this document DZNR means DZNR-768.
