2. Configure RS-232 Settings.
3. The RS-232 port can be used in two ways:
• Parameter Control: Connect a PC to the DVR using the PC serial port. Device
parameters can then be set using software such as HyperTerminal. The serial port
parameters must be the same as the DVR’s when connecting with the PC serial port.
• Transparent Channel: Connect a serial device directly to the DVR. The serial device
will be controlled remotely by the PC through the network and the protocol of the serial
device.
Note: Please note that the remote control features through the RS-232 port are limited.
12.4 Managing User Accounts
By default, your DVR comes with one user account, the Administrator account. The
Administrator user name is admin and the password is 12345. The default password for
Administrator should be changed right away for security reasons. The Administrator has
the authority to add, delete or configure parameters for many of the system functions.
Recommendation: There is no backdoor method for recovering a password so before
changing your password, it is recommended that you create a new user and password
with full
privileges so that you have a backup method if you make a mistake when
changing your password.
12.4.1 Adding a New User
