Chapter 2: Overview
2. Overview
2.1 Introduction
2.1.1 What is the AlertWerks ServSensor?
The AlertWerks ServSensors are intelligent devices for monitoring environmental variables, power, physical threats, and security.
The units are IP based and have a Web interface for configuration. Included in this is a TCP/IP stack, Web server, full SNMP, and
e-mail support.
Any of our Intelligent Sensors can be connected via the RJ-45 connections (excluding our 8-port, sensor-controlled relay, thermo-
couple, or PMS sensors), or you can add dry contact connection for monitoring UPS, security systems, and air conditioning status.

What’s the difference between the ServSensor Jr., ServSensor 4, and the ServSensor 8?
The ServSensor Jr. is a small unit with two RJ-45 sensor inputs, the ServSensor 4 has four RJ-45 sensor inputs, and the ServSensor
8 has eight RJ-45 inputs.
What’s the difference between the ServSensor 8 and the ServSensor X20?
The ServSensor X20 has eight RJ-45 intelligent sensor ports AND 20 extra dry contact inputs; the ServSensor 8 only has eight 8
RJ-45 sensor ports. For more on these extra dry contacts, see Section 2.4.5.

2.1.3 How to Use this Manual
This manual is a step-by-step guide on how to get your unit set up and functioning. It will introduce the primary features of the
unit by way of tutorials. You can either go through the whole procedure from start to finish, or, if you wish, use each tutorial as a
standalone lesson. The start of each lesson gives an “entry point profile,” which details how to get to the start point of the lesson
and assumes previous knowledge through completion of previous tutorials.
NOTE: Throughout this manual, you will find notes in each section that will relate to the information you are reviewing. Also,
Chapter 8 contains covers common questions and problems you may encounter. If you need any further assistance, contact

Chapter 2: Overview
2.4.5 ServSensor 8-X20 20 Extra Dry Contact Inputs
The 20 extra dry contact inputs on, for example, the ServSensor with 20 or 60 DC inputs, can be configured as inputs only up to
5 volts in normal operation. In opto-isolation mode, they can input up to 30 volts DC. This will protect these inputs and the unit
from high voltages and spikes.
Opto-isolators provide complete electrical separation between the ServSensor and the dry contact. The base units are therefore
protected against possible large voltage spikes caused by lightning for example.
Figure 2-9 shows the JUMPERS (on the dry contact board) set up to provide opto-isolator support. Opto-isolators provide
complete electrical separation between the ServSensor and the dry contact.
Figure 2-9. Jumpers on the dry contact board.
The OID for the extra dry contact inputs is:- .1.3.6.1.4.1.3854.1.2.2.1.18.1.3.<port>
Extra dry contact input practical applications:
The extra dry contact inputs can be used to monitor many types of equipment, for example, you can run the connection from
warning lights on alarm panels to the dry contact inputs, so that when the warning light on the alarm panel is activated, the dry
contact is triggered in the unit’s Web interface, enabling you to send notifications via e-mails or SNMP traps.

3. Installation
3.1 Assigning an IP Address
These units are plug-and-play devices that will easily connect to your existing network setup. Every unit ships with a default IP
address. This is 192.168.0.100. To install your unit, you must first assign it an IP address to match your current network
configuration. Before starting this, make sure you have the following items:
• RJ-45 CAT5 crossover cable with RJ-45 male connection
• A PC with Ethernet card or LAN socket.
• Power socket for the unit to connect to
1, Connect the unit via the CAT5 crossover cable to the Ethernet/LAN port on your computer.
2. Open your Web browser and go to the default IP address http://192.168.0.100.
Figure 3-1. Enter default address.
NOTE: In some cases, your computer might not be able to connect to this default IP address. In this situation, you need to set up
your computer’s routing table to allow access to this.
