NetGuardian 480/432 Overview
1
As an easy-to-install, high-density RTU, the NetGuardian effectively monitors sites with a lot of discrete alarm
points.
Effective, easy-to-install, light-capacity alarm monitoring
The NetGuardian (NG) is a compact, LAN-based, high-density remote telemetry unit. The NetGuardian is designed
for easy installation at remote sites with up to 80 discrete alarm points, making it cost-effective to deploy alarm
monitoring at your larger facilities.
Powerful monitoring for high-density sites
The NetGuardian is based on the time-tested NetGuardian 832A design. This telco-grade remote is housed in a
durable aluminum case. This SNMP remote is scaled to the needs of high-density sites that require a lot of discrete
inputs.
·32 (NetGuardian 432) or 80 (NetGuardian 480) Discrete Alarm Inputs
·4 Control Relay Outputs
·1 Reach-through serial port (terminal server)
Reach-through serial port gives LAN access to on-site equipment
The NetGuardian also features a reach-through serial port. This port provides remote users with LAN-based Telnet
access to a variety of on-site telecom equipment, including switches, radios, PBXs and many other devices.
SNMP or T/Mon
The NetGuardian can report alarms to any SNMP manager or to the DPS Telecom T/Mon Remote Alarm Monitoring
System. The NetGuardian can also report via SNMP and DCPx concurrently to the T/Mon.
Easy Alerts via Email or SNMP
Email notification reports alarm events to the e-mail addresses of specified personnel and creates a supplemental
record of alarm events in addition to your master via SNMP traps.
Upgraded Web 2.0 Interface
The overhauled web interface that boasts several time-saving new tools, including new analog gauges. You'll also
notice the impressive speed boost. Menus load very quickly, and the alarm status updates automatically without
requiring a page refresh.
Note: The NetGuardian 432 is a subset of the NetGuardian 480, so the content in this manual will be
applicable to both units. Any differences between the unitswill be clearly identified.

Power Connection6.1
The NetGuardian uses single or dual (Optional) power inputs, powered through two barrier plug power connectors.
NetGuardian Power Terminals and Fuses
To connect the NetGuardian to a power supply, follow these steps:
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 and tighten the screw; then
insert a battery line to the plug's left terminal and tighten its screw.
4. Insert a fuse into the fuse distribution panel and measure voltage. The voltmeter should read between
–40 and –70VDC (for -48VDC build option), +18 and +36VDC (+24VDC 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 Afuse 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.

9
LAN Connection6.2
To connect the NetGuardian to the LAN, insert a standard RJ45 Ethernet cable into the 10/100BaseT
Ethernet port on the back of the unit. If the LANconnection is OK, the LNK LED will light SOLID
GREEN.Serial Connection6.3
The NetGuardian has 4 build options for it's serial / dialup port. You can order your port as a Yost RS-
232, RS-485, 4-wire 202 RJ45/4-pin connection, or with a dial-up modem. The serial port is located
on the back panel.
!
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.
The serial port can be used for 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.
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.

Telecom's optional 66 block connector. For pinout and color-code information, see the diagrams below.
Note: The 66 Block supports termination of 22 - 26 AWG (0.81 - 0.41mm) solid insulated cable or 18-19
AWG (1.02 - 0.91mm) solid stripped cable. DPS recommends using 24 AWG wire (solid).

D-Wire Sensor Input (analogs)6.7
The port on your NetGuardian labeled "D-Wire" supports up the connection of up to 16 chained D-Wire
analog sensors. The NetGuardian powers and communicates with your D-Wire sensors via straight-
through RJ-11 cables.
Connecting D-Wire Sensors
Using a 6P4C, straight-through RJ-11 cable, connect the D-Wire sensor port on the NetGuardian to
the In jack on a D-Wire sensor. Chain additional sensors to the NetGuardian (using the same straight-
through cables) from the Out jack on the previous sensor to the In jack on the next (i.e. Out on sensor 4
to In on sensor 5).
Pinout for D-Wire RJ-11 jacks
Note: Some sensors may consume 2 of your NetGuardian's 16 analog channels (the combined temp/
humidity sensor, D-PK-DSNSR-12002, for example). Your NetGuardian can provide power to a sensor
chain up to 800 feet long.
The Integrated temperature build option uses one of the maximum 16 sensors that are supported.
The D-Wire line of sensors includes temp/humidity, additional analogs, discretes, and more. Contact
DPS at 1-800-693-0351 for information about available D-Wire sensors.
For details about configuring your sensors though the web interface, see the Sensors section of this
manual.

Quick Start: How to Connect to the NetGuardian
7
Most NetGuardian users find it easiest to give the unit an IP address, subnet and gateway through the
front USB craft port (TTYinterface) 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 and access its Web Browser. See the "...via LAN" section of this chapter.
...via Craft Port (using TTY Interface)7.1
1. The simplest way to connect to the NetGuardian is over a physical cable connection between your
PC's USB port and the unit's USB craft port. Note: You must be connected via craft port or Telnet
to use the TTYinterface. Make sure you are using a standard A-B USB cable (this same cable is
commonly used for USB printers) to make a USB craft port connection. We'll be using
HyperTerminal to connect to the unit in the following example - however, most terminal-emulating
programs are also compatible.
