Fig. 5.1 NetGuardian 16 back panel connections

Power Connection5.1

The NetGuardian 16 is powered by two barrier plug power connectors.

Fig. 5.2 Barrier plugs

To connect the NetGuardian to a power supply:

Always use safe power practices when making power connections. Be sure to remove fuses from the fuse distribution panel, as well as the back of the NetGuardian, before making your power connections.

Use the grounding lug to connect the unit to earth ground. The grounding lug is next to the symbol . Insert the eyelet of the earth ground cable between the two bolts on the grounding lug (Ground cable not included).

Insert a battery ground into the power connector plug's right terminal; then insert a battery line to the plug's left terminal.

Insert a fuse into the fuse distribution panel and measure voltage. The voltmeter should read between +11 and +18 (for +12VDC build option), –40 and –70VDC (for -48VDC build option) or -18 and -36VDC (-24VDC build option).

The power plug can be inserted into the power connector only one way to ensure the correct polarity. Note that the negative voltage terminal is on the left and the GND terminal is on the right.

Insert fuse into the Power A fuse slot. The power LED should be lit green. If the LED is red, the power connection is reversed. To confirm that power is correctly connected, the front panel LEDs will flash RED and GREEN, indicating that the firmware is booting up.

Repeat steps 1 -6 for Power B connector.

LAN Connection5.2

Hot Tip!

If you are unsure of the serial port type on your NetGuardian, login to MyDPS and click on the Product Information Search link. Type in the full part number of your unit and click the Submit button to access the specifications.

To connect the NetGuardian 16 to the LAN, insert a standard RJ45 Ethernet cable into the 10BaseT Ethernet port on the back of the unit. If the LAN connection is OK, the LNK LED will light SOLID GREEN.

Serial Connection5.3

The NetGuardian 16 has 4 build options for it's serial / dialup port. You can order your port as a Yost RS-232, RS485, 4-wire 202 RJ45, or with a dial-up modem. The serial port is located on the back panel, where it is labeled

"Primary."

Fig. 5.3 Serial Port Pinout

The serial port can be used for three different functions:

Reach-through proxy connection for LAN-based Telnet access to switches, radios, PBXs and other equipment. Alarm reporting to the T/Mon Remote Alarm Monitoring System over an RS-232, 485, 202, or dial-up modem. Dial-up notifications via your cell phone and alphanumeric pager.

Note: If the serial port is configured for alarm reporting to T/Mon, the port is not available for use as a reach-through proxy port.

The pinouts are shown in Fig. 5.3 .

50-Pin Alarm and Control Relay Connector5.4

The primary connectors for discrete alarms, analog alarms and control relays are the 50-pin connectors on the NetGuardian 16's back panel.

Optional 66 Block Connector5.5

Fig. 5.6 Discrete alarm points can connect as a dry contact or a contact to ground

The NetGuardian 16 features 16 discrete alarm inputs - also called digital inputs or contact closures. Discrete alarms are either active or inactive, so they're typically used to monitor on/off conditions like power outages, equipment failures, door alarms and so on.

The NetGuardian's discrete alarm points are single-lead signals referenced to ground. The ground side of each alarm point is internally wired to ground, so alarm points can connect either as a dry contact or a contact to ground.

Note: Make sure that grounds have a common referencethis is usually done by tying grounds together.

In a dry contact alarm: The alarm lead brings a contact to the ground lead, activating the alarm.

In a contact to ground alarm: A single wire brings a contact to an external ground, activating the alarm.

You can reverse the polarity of each individual discrete alarm point, so that the alarm is activated when the contact is open. This is done with a software configuration change.

Craft Port6.1

1. The simplest way to connect to the NetGuardian 16 is over a physical cable connection between your PC's COM port and the unit's craft port. Note: You must be connected via craft port or Telnet to use the TTY interface. Make sure you are using the straight through (1 to 1) Male to Female DB9-DB9 download cable provided with your NetGuardian 16 to make a craft port connection. We'll be using HyperTerminal to connect to the unit in the following example - however, most terminal-emulating programs should work.

To access HyperTerminal using Windows:

2. Click on the Start menu > select Programs > Accessories > Communications > HyperTerminal.

Use the front panel craft port to connect the NetGuardian 16 to a PC for onsite unit configuration. To use the craft port, connect the included DB9 download cable from your PC's COM port to the craft port. Pinout is shown above for reference, but this is a standard DB9 to DB9.

Fig. 6.1 Craft port pinout

Most NetGuardian users find it easiest to give the unit an IP address, subnet and gateway through the front craft port (TTY interface) to start. Once these settings are saved and you reboot the unit, you can access it over LAN to do the rest of your databasing via the Web Browser interface.

Alternative option: You can skip the TTY interface by using a LAN crossover cable directly from your PC to the NetGuardian 16 and access its Web Browser. See Section 7.2.

Description

User-definable description for the discrete alarm input.

Rev (Reverse)

Reverse: Check this box to reverse the polarity of the alarm point. Left un-checked, this means a normally-open contact closure is a clear condition. When polarity is reversed, a normally-closed alarm point is clear when closed.

Example: Door with a magnetic door sensor. When the door is closed, the magnetic sensor acts like a closed relay. However, you know this should not trigger an alarm condition. This means you'd want the door alarm reversed in the NetGuardian because we are looking for a normally closed condition.

Notification devices

Check which notification device(s), 1 through 8, you want to send alarm notifications for that alarm point. These notification devices correlate to one of the 8 devices you setup for notification (email, SNMP trap, etc.) Check the box in the green bar (top) to have a notification device send an alarm for all alarm points.

7. Now you will associate this notification to an alarm (system, base, analog, etc.) You have 8 notification devices

available to use. In the image below, you might assign Notification Device 1 to Base Alarm 1. This means that you would receive an email notification when an alarm for SERVER ROOM occurs. Remember that Notification #1 in the Notifications menu is the same as N1 on the alarms page.

How to Setup Analog Alarms10.4

Login to the NetGuardian web browser and click the Edit > Analogs menu. Click the Enable checkbox next to the analog number to turn the analog alarm ON.

Fig. 10.12

Next, give this analog alarm a Description, then click the Save button at the bottom of the page.

Click the Advanced link at the top of the Edit > Analogs menu to edit more specific information. Start by selecting thresholds. The threshold values in this example will be temperatures values. These thresholds tell the NetGuardian that I want be notified of when the temperature rises above or drops below these set levels. In this example, we are selecting:

On Set and Clear: Here there are fields labeled “On Set” and “On Clear”. These allow you to customize the description of an alarm fail and clear. For example, if you’re monitoring a Propane tank, it might make more sense to see the word “Empty” instead of “Alarm”.

QTime: Stands for Qualification time. Here, the qualification time is set for 1 minute. By clicking this link, the help text will explain that 1S=1 second, 1M=1 Minute, and 1H=1hour. Typically, when an analog sensor crosses a threshold, it does not stay there – It usually waivers across the threshold value. This may cause many alarms, and possible many nuisance emails. Here, we will set the qualification time for I minute, meaning we will only see this alarm if the value is across the threshold for 1 minute or longer. The same is true for the clear condition – We

only want to know it has cleared if it stays clear for longer than 1 minute.

Fig. 10.20

Example, this temperature sensor is a current loop sensor that outputs 4-20mA. The NetGuardian uses a 250 Ohm resistor to convert current to voltage measurement. Ohms

law says:

4mA X 250 Ohms = (0.004 X 250) = 1VDC

AND

20mA X 250 Ohms = (0.020 X 250) = 5VDC

The documentation that came with this sensor explains how 4 - 20 mA translates temperature. In this case:

4mA (or 1VDC) = 32º F

AND

20mA (or 5VDC) = 131º F

Therefore, my reference values are 1 = 32 and 5 = 131.

Display Units: This is the 3 unit value the NetGuardian will display as the label for the units you want to measure. This field is only used for readability - It does not affect how the NetGuardian works with your analog sensor. For this example, we want to show “F” for Fahrenheit. Other entries you might want to use for analog measurements are “%H” for Percent Humidity, “Knt” for Knots (wind speed), “LBS” pounds of pressure, etc.

High/Low Reference: The Low and High Reference values are how the NetGuardian will determine the temperature based off the input voltage. You will find these values in the documentation that came with the sensor you are using. The NetGuardian is trying to build a linear equation to give you the most accurate results. For example, if you are measuring battery voltage, you’d want the NetGuardian to display -54VDC when the input voltage is in fact -54VDC. However, if you’re measuring temperature instead, this relationship won’t always be a 1:1 ratio.

Lastly, pick an analog gauge that best fits this sensor. Before you save, review the Threshold Values you entered earlier. These might have been recalculated based off the newly entered reference points. Reboot the

NetGuardian to save your changes.

Log back into the unit and click Analogs from the (blue) Monitor menu. Now you should be able to view your

54.2 VDC is really being measured. However, if you are measuring temperature, the values are typically not a 1 : 1 ratio.

Example 2: Your X-Type sensor outputs 4 - 20mA. (We use a 250 ohm resistor to convert current to voltage measurement. Ohms Law tells us that 4mA x 250 ohms = 5 VDC. The sensor should tell us what the output current references. In this example, 4mA = 23º F and 20mA = 131º F OR 1V = 23º F and 5V = 131º F.
