W&T IP-Watcher 2x2 Digital PoE
1. Introduction
The IP Watcher from W&T uses cyclical polling to monitor
network components. If a device no longer responds, this
status can be reported by triggering local or remote alarms.
Local alarms indicate non-response by switching a connected
consumer on one of the two digital outputs. A remote alarm is
set for example by email, FTP, SNMP or Syslog over a TCP/IP
network.
An individual acknowledgement can be configured for all
alarms. This is done either by wiring one of the digital inputs
on the device (hardware acknowledgement) and/or sending an
acknowledgement command via TCP/IP from the controller side
to the IP Watcher (software acknowledgement). An
acknowledgement ensures proper detection and handling of an
alarm situation by an operator.
An integrated Web server provides configuration pages for
setting the device parameters. Browser-based software is used
to operate and monitor the alarms, and can also be loaded from
the Web server of the IP Watcher into any browser. This software
is self-refreshing and indicates the status of the activated
alarms while offering the possibility of acknowledging pending
alarms.
Power can be supplied either via Power over Ethernet through
the network or from an external power supply.
The properties of the IP Watcher make it ideal for stand-alone
monitoring tasks. Switching an output when there is an alarm
can generate a local response, for example turning on a rotating
flashing beacon. An alarm sent over a network quickly reaches
even distant personal and prompts them to act. Network
alarming allows the use of an existing network infrastructure
and thereby makes it possible to send messages individually
and without additional cabling. Thanks to the built-in, browser-
based software, operation and monitoring are possible not only
in the Intranet, but also worldwide over the Internet.

2. Startup
Just a few steps are needed to incorporate the IP-Watcher into
your network and get it running.
2.1 Supply voltage
The following describes the two methods of providing power
to the IP-Watcher.
The types of voltage supply described here provide only power
to the device. Wiring the in- and outputs requires an additional
power supply.
If the device is powered using PoE, connecting or dis-
1connecting an additional external power source while
the device is running may result in the IP-Watcher restarting.
2.1.1 External supply voltage
Connect a supply voltage of 18V...48V DC (+/-10%) or
18Veff...30Veff AC (+/-10%) to the terminal on the underneath
of the device. You may use power supplies sold by W&T or any
desired power supply which meets the technical requirements.

W&T IP-Watcher 2x2 Digital PoE
The external supply voltage for the device is always
1required in networks not providing PoE, but may also be
used in PoE environments.
When powering with DC voltage, correct polarity is not required.
It is also possible to power the device with 12V DC. There
however you must take into account the very poor efficiency of
the power supply and the associated elevated current draw.
2.1.2 Voltage supply using PoE
The IP-Watcher is equipped for use in Power over Ethernet
environments per IEEE802.3af. The voltage is then provided by
the network infrastructure using the RJ45 terminal. The device
supports both phantom feed using data pairs 1/2 and 3/6 or
spare-pair power using the unused wire pairs 4/5 and 7/8.
To enable power management for the supplying components,
the IP-Watcher identifies itself as a Power Class 2 device with a
power draw of 3.84W to 6.49W.
With an external power supply the IP-Watcher can also
1be used in networks not providing PoE support.
2.2 Network connection
The IP-Watcher provides an IEEE 802.3 compatible network
connection on a shielded RJ45 connector. Pin assignments
correspond to an MDI interface (see figure), so that connection
to a hub or switch is made using a 1:1 wired and shielded patch
cable.
