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:
1.
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.
2.
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).
3.
Insert a battery ground into the power connector plug's right terminal; then insert a battery line to the plug's left terminal.
4.
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).
5.
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.
6.
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.
7.
Repeat steps 1 -6 for Power B connector.

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.
Contact to Ground

– Batt.
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.

The NetGuardian 16's 8 analog alarm inputs measure continuous ranges of voltage or current. Analog alarms are typically used to monitor battery voltage, charging current, temperature, humidity, wind speed, or other continuously changing conditions. The measurement range of the analog channels is – 90 to +90 VDC or 4 to 20 mA. To configure the analogs for current sensing (4 - 20mA) please review the next section for jumper position.
You can use analogs 1 through 4 to monitor whatever you like. Analogs 5 through 8 are pre-configured to monitor Battery A and B, Internal Temperature, and External Temperature. Read the following table to see where to connect the analogs.

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.
