 Login button: This button is enabled when login is required.
InstaCal's configuration page also lists the unique 64-bit physical (MAC) address assigned to the device. You
cannot change this address.
Logging in to a device session
You must be logged in to a device session in order to change the configuration settings of a device or change
the state of the digital outputs. A user name and password are required to log in if they are not set to the
default values. For security, it is recommended that you change the login values from the defaults. The log in
session times out after five minutes of inactivity.
The default user name is set to webtemp for the WEB-TEMP, and webtc for the WEB-TC. The default
password is mccdaq for both devices. You can change these values in InstaCal with the Change Login button
after you are logged in to a device session. Each value can be up to eight alphanumeric characters.
Using InstaCal, when the user name and password have been changed from the default values, the
configuration page opens with configurable items disabled and the Login button enabled. Click the Login
button and then enter the values. The INVALIDLOGIN error is returned if the login information is not valid. The
SESSIONINUSE error is returned if you attempt to log in when a session is currently open by another user. Only
one user can be logged in to a session at a time.
Similarly, applications written with the Universal Library will perform a background log in when required if
the login parameters are set to the default values. If custom values have been set, you have the option to allow
the default login dialog to pop up when required or to disable the default dialog and handle login in your code.
To disable the default login dialog when using the Universal Library, you can select the "Show Login dialog
prompt" option in InstaCal, or for a more permanent result, disable the default dialog using cbSetConfig()
with the BIHIDELOGINDLG ConfigItem argument within your application code.
Factory default reset
To restore the network parameters (including the user name and password) to the factory default settings,
press and hold the device's reset button for three seconds. You do not have to be logged in to restore the
default network settings.
Manually adding a device to InstaCal
If a device is not yet connected to the local network, or if it is connected remotely to a different LAN,
InstaCal will be unable to detect it. If autodetection fails, you can manually add the device to InstaCal using
the Web tab on the Board Selection List dialog, and specify the IP address and port to use in the broadcast.
The default IP address and port add a placeholder to the configuration of a WEB device detected on the
network. The default IP address broadcasts to all devices detected on the local subnet. The default port lists
the default port number that is used to interface with the UL.
Any instance of the device type responding to the broadcast will attach to the placeholder. You can specify the
device to attach to the placeholder by clicking the MAC check box and entering the device's type and instance
ID. Enter C0 to locate a WEB-TC, or C2 to locate a WEB-TEMP. Enter any value from 0x00000 to 0x2FFFE
(except 0x1FFFF) for the instance ID. The first three octets of a MAC address indicate the vendor ID and
cannot be changed.
Configuring the DIO channels to generate alarms
The WEB-TEMP and WEB-TC provide eight independent temperature alarms. Each alarm controls an
associated digital I/O channel as an alarm output. The input to each alarm is one of the temperature input
channels. You set up the temperature conditions to activate an alarm, and the output state of the digital
channel (active high or low) when activated. You can view the alarm status on the web browser.
