1. INTRODUCTION
GATEWAYBN0 (hereby called “Gateway”) is a Carel electronic device that allows to interface Carel-controllers (maximum
number: 8) with systems communicating with the
BACnet. This is a frequently used protocol and a property of many BMS
manufacturers. The device makes automatically the translation of the Carel transmission protocol into the communication
protocol BACnet.
The protocol translator has been created to allow the connection of each Carel peripheral to BACnet systems using a
standard gateway, i.e. without the need of following and expensive software adaptations.
1.1 General description
The reference BACnet protocol is the one defined by the official document:
ANSI/ASHRAE
Standard 135-1995
Approved by the American National Standards Institute
December 19, 1995
The connections available on the Gateway are:
•
serial 232 (protocol PTP) towards the BACnet;
•
serial 422 or 485 towards Carel peripherals;
•
serial 232 for the Gateway configuration.
The power supply can be selected among the following three values: 220Vac, 120Vac or 24Vac.
Up to 8 Carel peripherals can be connected to the Gateway.
A program is supplied together with the product to configure the Gateway according to the particular requirements of the
application and peripheral network to be supervisioned.
