Security
The AcquiLite has three levels of security. These are “operator”, “user” and “admin”. When using a browser to access the
AcquiLite, basic http authentication is used to prompt your browser for a username and password. The admin account uses
“admin” as the default password. To change the password, select the Accounts menu from the left side tree display. Next,
select the account name. Click the “Change Password” button to set a new password for the selected account.
admin
: This account has full access to modify any of the system settings. The default password is “admin”.
operator
: This account may view settings, however may only change modbus alarm ranges and device names.
user
: This account can view some system settings including the modbus device status pages and can change nothing.
When using FTP to access the AcquiLite, you may use the admin account username/password for read-only access. Log
information is stored in /var/log/modbus. For read-write-delete access, use the login name “root” and the admin password.
The three usernames specified are not able to be changed or renamed, nor can arbitrary usernames be added to the
AcquiLite. Access is only controlled by setting the password for the three existing usernames noted above.
The “operator” and “user” accounts are disabled by default. These accounts are activated when you first set a password for
each.
Modbus
Device List
The Modbus Device List page will show a listing of all the devices the AcquiLite has configured. The device list will show
the Modbus address number, status (OK, Error, Alarm, Unconfigured), the device name (user specified) and the device
identification string. Device 250 represents the onboard pulse input channels. Other devices must be added using Modbus
TCP.
Click on the Modbus address number for any of the devices for specific device details
