Ring Communications DNA300 - Manual (Page 5)

DNA300 OPERATIONS MANUAL 5 2006/06/13
INTRODUCTION
A serial RS232 device can be interfaced to the Crisis Alert Network for the purpose of handling incoming and
outgoing calls assosiated with one of the Crisis Alert master stations.
Examples of other display devices would be graphics annunciator panels, touch screen annunciators, or any
other graphical user interfaces not made by Ring Communications, Inc.
One DNA300 is required to interface each external device to the network. Each DNA300 must be asigned to a
master station in the exchange controller DXC901/DXC910 (the same way as when using DAD104).
INSTALLATION
INTRODUCTION
The Digital Network Adapter (DNA300) interfaces one external RS232 or RS422 device to Ring Communications’
Crisis Alert System.
The DNA300 operates on +24 VDC. It can be powered from the central exchange or can be powered locally by a
separate 24 VDC regulated power supply.
The recommended cord is the BF640A to connect the DNA300 to the RJ45 network jack, KB171. Cords and
jacks must be ordered separately.
