Configure the Wafer Reader

To Suppress the
HTTP Logon Dialog When Connecting to a Wafer Reader:
The user name and password can be specified as part of the address, allowing you to
suppress the HTTP Logon dialog. The address must be typed using the following format into
the browser's Address Box:
http://hostname/filename?isSL=username+password
NOTES
■ “?isSL=username+password" is case sensitive; no spaces are allowed. If there is no password, leave
it blank, without spaces. The “+” must be included, even if no password is entered.
■ A filename must be specified.
■ “hostname” can be either the Host Name or the IP address of the wafer reader.
■ During a single HTTP session, do not connect to a wafer reader using both the HTTP Logon dialog
and without.
Examples:
To log on as admin, with no password and open the WaferID.html file:
http://is1721_00060b/WaferID.html?isSL=admin+
To log on as admin, with the password Cognex and open the WaferID.html file:
http://192.168.0.1/WaferID.html?isSL=admin+Cognex
