Number Component Description
1 Power LED When the unit is powered on, the power LED will be lit continuously. If the
power LED is flashing, there is a problem with the CPU. Contact Technical
Support at 724-746-5500 or [e-mail].
2 Link LED The Link LED indicates network connectivity. It lights when a network is
connected to the ServSensor V4E Lite.
3 Mic The mic is a small hole for access to the internal microphone. Use it as a
sound sensor (or use an external mic).
4 SD memory card slot Place your SD card in the removable SD memory card slot. It can store sounds
recorded from the internal microphone and also the current firmware of the
unit.
5 Activity LED The Activity LED flashes when network traffic is sent to or received by the
ServSensor V4E Lite.
6 Status/Online LEDs 1–8 The Status/Online LEDs are numbered 1–8. They indicate the connectivity
status of the sensors connected to each port. You can also use these LEDs to
indicate system status during various operations.
Additionally, the LEDs can indicate the progress of an upgrade. The red LEDs
move from left to right to indicate activity, and all the green LEDs indicate
overall progress of the upgrade. When all the red lights are off and the green
are on, the upgrade/recovery process is complete.
These lights also indicate if the unit is operating in safe mode. This is when
the unit loads the operating system (OS) with a minimal set of drivers. If your
device enters safe mode after rebooting, contact Black Box Technical Support
at 724-746-5500 or [e-mail].
The unit may enter recovery mode if a firmware upgrade is incomplete. In this
case, the unit displays a continuously lit row of red LEDs. If this happens,
contact Black Box Technical Support at 724-746-5500 or [e-mail].

Chapter 2: Overview
2.4 ServSensor with 20 or 60 Extra Dry Contact Inputs, VAC, or VDC
The 20 or 60 extra dry contact inputs on the ServSensor 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.
The figure below shows the jumpers (on the dry contact board) set up to provide opto-isolators support.
Refer to the rear panel of the ServSensor above for the other connections on the rear panel, as they are exactly the same in
functionality.
Figure 2-9. Jumper settings.
The OID for the extra dry contact inputs is:- .1.3.6.1.4.1.3854.1.2.2.1.18.1.3.<port>
2.4.1 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, thus allowing you to send notifications via emails or SNMP traps.

2.4.2 ServSensor with 20 or 60 Extra Dry Contact Web Interface Setup
Figure 2-10. Sensors page.
First login to the ServSensor Web interface, then navigate to the Sensors Page, then click on the Dry Contact Ports link in the left
hand column. You can now click on the dry contact port to set up that port as shown in the screen shot above.
Figure 2-11. Normal settings screen.
In the Normal tab settings we can see that the sensor is currently offline, so to enable the dry contact port we would click on the
Offline button.

Figure 2-12. Critical status screen.
We can see the dry contact input is now Critical and we can set how we require the Normal State to be as shown above—either
in the Closed GND or Open +5VDC. We can also rename our normal and critical state of the input.

Chapter 3: Installation
3. Installation
3.1 Setting Up the IP Address
The ServSensor V4E Lite is shipped with the default IP address of 192.168.0.100. Follow the steps listed below to change this IP
address to fit your own network configuration.
Before starting, make sure you have these items:
• (1) RJ-45 male CAT5 crossover cable
• (1) PC with Ethernet card or LAN socket
• (1) Power socket for the unit to connect to
To set up the IP address:
1. Connect the ServSensor V4E Lite via its Ethernet port to your computer’s Ethernet port with a CAT5 crossover cable.
2. Open a Web browser and type the default IP address (as in Figure 3-1), then press the Enter key.
Figure 3-1. Google Web Browser screen.
NOTE: In some cases, your computer might not be able to connect to this default IP address. In this situation, you will need to
change the IP address of your PC. See the instructions above.
3. After you press the Enter key in Step 2, Figure 3-2 appears. The default password for Admin is “public.” Change the password
to make your unit secure.
