Choosing an ISP
There is a large selection of ISPs available with a variety of service plans.
Walchem recommends selecting an ISP that has easy access and is reliable.
Some ISPs can have spotty coverage that can be very unreliable during peak
hours. ISPs that require you to load software will not work.
Walchem recommends the following ISP for best results:
Information is available at www.surfbest.net or by dialing
(207)-384-4234
EARTHLINK is also reliable in many locations. Information is available at www.earthlink.com or
1-800-EARTHLINK.
If you want to receive e-mails from your controller (alarms, datalogs and system summaries) your
ISP will provide you with an SMTP server address.
The Communications section of the Instruction Manual provides additional instructions on
receiving e-mails.
The Auto Reporting section in the Instruction Manual contains detailed information on auto-
reporting.
DirectTap Modem-to-Modem
Your WebMaster/WebAlert can also be accessed via DirectTap modem-to-modem
communications. DirectTap is primarily used as a diagnostic tool or for initial set-up. DirectTap
enables the user to connect directly to the WebMaster/WebAlert via a phone line without using
the Internet. When the Internet is not available or at peak Internet usage, you can access your
device directly with your modem. Unlike ShoulderTap, DirectTap is limited to one user at a time.
DirectTap can be used to dial into a controller for initial set-up. The modem option is required to
DirectTap.
Refer to the Instruction Manual.
Ethernet
Your WebMaster/WebAlert can be placed directly on a Wide Area Network (WAN) or Local Area
Network (LAN) just like any PC or standard piece of office equipment such as a network printer.
The device only needs to be assigned an IP address from the on-site IT administrator for access via
an Ethernet connection for a WebMaster/WebAlert.
The Instruction Manual provides a step-by-step guide for Ethernet communications.
