Fig. 1.2. The NetGuardian 216 supports both DCP and Dial-up reporting of alarms to T/Mon
Complete LAN Access to Your Remote Site
IP-based connectivity means the NetGuardian 216 can be installed anywhere your LAN goes. You can add alar
m
monitoring visibility to anywhere in your network, without installing expensive dedicated circuits or relying on
modem connections to transport essential data.
Multiple Protocol Support
The NetGuardian 216 reports alarms via DCP, DCPf, DCPx or DCP1 over UDP/IP or TCP/IP. This allows the

2
N
etGuardian 216 to report to any T/MonXM Alarm Management System over LAN. The NetGuardian 216 also
comes equipped with a modem, which enables it to report to T/Mon over a standard phone line. Dial-up reporting
can be configured for either normal or back-up modes by setting call options with T/NG216-Dialup, enabling you
to prevent toll charges from nuisance alarms. Use the NetGuardian 216's dial-up reporting as an alternate path, so
you can rest assure that alarms will be sent to T/Mon even if the LAN is down. You can also configure
a
secondary phone number to dial out to T/Mon in the event the first number the NetGuardian 216 tries is
unavailable.
Easy Installation and Configuration
The NetGuardian 216 mounts in any 19" or 23" rack and occupies only ½ rack unit of space. The standard
N
etGuardian 216 has rear-panel connectors for alarms, dial-up connections, relay outputs, and analog inputs.
Configuration settings can be entered through T/NG216-Dialup. Configuration information is saved to the
N
etGuardian's nonvolatile RAM (NVRAM), where it is secure even during power outages.

4.6.1 Preliminary Network Configuration
In order for the NetGuardian to become configurable over the LAN, the IP address of the NetGuardian must be in
the same subnet or on the same hub as your computer or network. The NetGuardian has a default IP address of
192.168.1.100 and a default subnet mask of 255.255.0.0. Configuring the NetGuardian to be in the same subnet as
your computer or network can be achieved in one of two ways:
1. The most commonly used method: by accessing the NetGuardian via the front panel craft port and changing
the IP address and subnet mask of the NetGuardian to match those of your computer or network, or
2. By temporarily changing the IP address and subnet mask of your computer in order to coincide with the
N
etGuardian's default IP address and subnet mask — Once you are in the same subnet as the NetGuardian's
default settings, you can access the NetGuardian and change it's IP address and subnet mask in order to
coincide with your computer or network settings.
To temporarily adjust your computer's IP address and subnet mask to correspond to these settings, follow these
steps:
1. Access and write down your computer's IP address and subnet mask.

9
2. Temporarily change your computer's IP address to 192.168.1.200 (In a Microsoft Windows setting, the IP
address and subnet mask settings are typically found in the Control Panels - Network - TCP/IP window).
3. Temporarily change your computer's subnet mask to 255.255.0.0.
Note: You will be prompted to automatically reboot your computer to initiate the changes.
4. You can now access the NetGuardian using T/NG216-Dialup over LAN using the NetGuardian's factory
default IP address, 192.168.1.100. Assign the NetGuardian an IP address and subnet mask on your network.
5. Change your computer's IP address and subnet mask back to their original settings.
Once the IP address and subnet mask of your computer coincide with the NetGuardian's, you can configure the
N
etGuardian via T/NG216-Dialup. After you have configured the NetGuardian with the appropriate information,
change your computer's IP address and subnet mask back to their original settings.

Configuration and provisioning of the NetGuardian can be performed from a PC connected to the unit's fron
t
p
anel craft port or over the LAN.
Alarm and Control Relay Connections4.7
Fig. 4.10. Alarm and control relay connectors
Discrete alarms, analog inputs, and control relays are connected to the NetGuardian using the 50-pin connecto

Fig. 4.11. Discrete alarm points can connect as a dry contact or a contact to ground
The NetGuardian 216 supports up to 16 discrete alarm inputs. Discrete alarms are typically used to monitor door
alarms, power outages, equipment failures, and other on/off conditions.
Discrete alarm points connected to the NetGuardian are single-lead signals referenced to ground. The B side of
each alarm point is internally wired to ground, so either a single wire bringing a contact to ground or a dry closure

11
with the second lead connected to the B side will be sensed as an alarm signal — see Figure 4.11 for an alar
m
connection diagram. To reverse the alarm point polarity so an open contact triggers an alarm point see section 5.8
(Editor Alarms Tab) for more information.
Connect discrete alarms to the 50-pin connector on the back panel. See Figure 4.12 for alarm and analog pinout
information.
Note: Make sure that grounds have a common reference usually accomplished by tying grounds together.

4.7.2 Analog Alarms
The NetGuardian 216's two analog inputs measure ranges of voltage or current inputs and can be used to measure
b
attery voltage, charging current, temperature, or other continuously variable conditions. The measurement range
of the analog channels is –90 to +90 VDC or 4 to 20 mA. Note: Default configuration is voltage.
Connect analog inputs 1-2 to the 4-pin connector labeled "Analogs."
