About this document
This manual is written to function as the user guide for both those groups who design and
specify alarm collection systems and those groups who install and maintain alarm
collection systems in the field. This manual is divided up into the following sections:
•
Product Description
— this section gives an overview of the Centurion II including
brief explanations of the various options which are available when ordering an RTU.
•
Installation and Configuration Options
— this section contains tables, which describe
the pin outs for the discrete input wiring, control relay outputs, and RS-422/485 serial
ports. Figures showing the relay jumpering options and the dip switch settings on the
I/O modules are also provided.
•
Installing an RTU
— this appendix describes the steps an installer should follow
when installing an RTU and configuring the RTU so that it communicates over a
LAN. Downloading a database is not covered in this manual.
•
How to Build Your Own Crossover Cable
— this appendix describes how to wire an
RJ-45 10BaseT cable so that two Ethernet adapters (e.g. on your PC and the
Centurion II) can communicate directly, without a hub. This section also describes
how to configure the IP and Subnet Mask addresses on your PC so that you can
communicate to the RTU using the Crossover Cable.
