Command Syntax; Data Logger Enclosures - Campbell CR300 Series Product Manual

Create an encrypted password file or modify an existing password file using Device Configuration
Utility:
1. Connect to your device in Device Configuration Utility.
2. Click the Network Services tab, then the Edit .csipasswd File button.
3. Define user accounts and access levels.
4. Click Apply. The .csipasswd file is automatically saved to the data logger CPU drive.
When a .csipasswd file is used, the PakBus/TCP Password security setting is not used when
accessing the data logger via HTTP. If the .csipasswd file is blank or does not exist, the
default user name is "anonymous" with no password and a user level of read only.
When access to the data logger web server is attempted without the appropriate security level,
the data logger will prompt the web client to display a username and password request dialog. If
an invalid username or password is entered, the data logger web server will default to the level of
access assigned to "anonymous". As noted previously, anonymous is assigned a user level of
read-only, though this can be changed using Device Configuration Utility.
If the numeric security code has been enabled, and no .csipasswd file is on the data logger,
then that numeric security code must be entered to access the data logger. If a .csipasswd
file is on the data logger, the username and password employed by the basic access
authentication will eliminate the need for entering the numeric security code.

16.2.3.1 Command syntax

Syntax for the commands sent to the web server generally follows the form of:
URL?command=CommandName&uri=DataSource&arguments
Arguments are appended to the command string using an ampersand (&). Some commands have
optional arguments, where omitting the argument results in a default being used. When
applicable, optional arguments and their defaults are noted and examples are provided in the
CRBasic help (search Web Server/API Commands).

16.3 Data logger enclosures

The data logger and most of its peripherals must be protected from moisture and humidity.
Moisture in the electronics will seriously damage the data logger. In most cases, protection from
moisture is easily accomplished by placing the data logger in a weather-tight enclosure with
desiccant and elevating the enclosure above the ground. Desiccant in enclosures should be
changed periodically.
