4. Select Use the following IP address option and enter the following:
o IP address: Enter 192.168.0.102. Note that the last three digits of this number can be any number
between 11 and 254, inclusive, but must be different from the IP address assigned to the device. The
default IP address set for the WEB-TC is 192.168.0.101.
o Subnet mask: Enter 255.255.255.0.
o Default gateway: Enter 192.168.0.1.
Caution! Assigning an arbitrary IP address could result in duplicate IP addresses on the network. This
condition can cause a communication failure that affects both devices. Make sure when
configuring static IP addresses that you set different addresses for each device.
5. Click OK .
6. Connect the WEB-TC's Ethernet port to your Ethernet hub using the supplied cable, or to your computer's
Ethernet port using a CAT-5 or higher crossover cable.
Note : If you connect to an Ethernet hub, you can use the Ethernet cable shipped with the device. If you
have multiple WEB-TC devices, configure each device separately and assign a unique IP address to each
device. You’ll need to run InstaCal to change the IP address from the default 192.168.0.101.
When connected, the Link/Activity LED illuminates steady green to indicate that you have established a
valid Ethernet connection, and blinks indicating network traffic. Refer to Figure 5 on page 22 for the
location of the
Link/Activity LED.
7. Open your browser and enter the URL address that is printed on the device label.
The WEB-TC Measurements page opens. You can view current measurement data from this page.
Configuring the WEB-TC
All hardware options are configurable with InstaCal or the web interface. InstaCal must be used if any of the
network parameters need to be changed, such as the IP address of your device. Configuration settings are stored
in non-volatile memory in EEPROM, and are loaded on power up.
Refer to the sections "Using the web interface" below and "Configuring the WEB-TC using InstaCal" on page
15 for detailed information.
Using the web interface
You can view current measurements and configure hardware options from the device's web interface. The web
interface provides four tabs. Each tab represents an HTML page that is stored on the device.

Measurements tab (home page) – lists the thermocouple measurements, digital values, and alarm status
read from each channel on the WEB-TC.
