Page 8: Introduction
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. -
Page 9: Startup
W&T IP-Watcher 2x2 Digital PoE 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. -
Page 10: Voltage Supply Using Poe
W&T IP-Watcher 2x2 Digital PoE The external supply voltage for the device is always required 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. -
Page 11: Wiring The Inputs
W&T IP-Watcher 2x2 Digital PoE The factory default setting for the IP-Watcher on the network side is for Auto-Negotiation. Data transmission speed and duplex procedure are automatically negotiated with the connected switch/hub and set appropriately. The network connection is galvanically isolated to 1kV with respect to the power supply as well as the digital IOs. -
Page 12: Wiring The Outputs
W&T IP-Watcher 2x2 Digital PoE If you need to use the inputs for monitoring the states of po- tential-free contacts, the supply voltage for the unit can also be used as the signal voltage. In this case you need to operate the IP-Watcher with a DC voltage of 12V-30V. -
Page 13: Assigning The Ip Address Using Wutility
W&T IP-Watcher 2x2 Digital PoE supply for supplying the outputs as well, but use no more than 30V for powering the device. In the configuration you can set up, to give the power supply of the IP-Watcher directly to the terminals Vdd and GND. In this case an external supply for the IOs is not required. - Page 14 W&T IP-Watcher 2x2 Digital PoE WuTility with found W&T network device Use the button IP address to go to the configuration dialog box.
