Set the Password for VNC Connection
The default VNC settings (no password) prevents you from establishing a VNC
connection to the terminal. You must set a view-only or control access password
before you can connect to the terminal with the respective access rights.
Follow these steps to set a password for VNC connection to the terminal.
1.
Press Enable/Disable to enable the VNC server.
Access
(1) Switch between view-only and control access
for the VNC connection to the terminal.
View-Only – No interaction allowed. Only the
current screen on the terminal is displayed.
Control – Interaction allowed. View-Only
View-Only Password Resets the current password a user must
enter when establishing a VNC connection to
the terminal for view-only access.
The password is a maximum of seven
alphanumeric characters (A...Z, a...z, 0...9).
No password
(2)
Control Password Resets the current password a user must
enter when establishing a VNC connection to
the terminal for control access.
The password is a maximum of seven
alphanumeric characters (A...Z, a...z, 0...9) and
special characters ('_', '$', '-', and '!'). A
minimum of one special character is required
for the control access password.
No password
(2)
(1)
It is recommended to enable only the view-only access to the terminal. Enabling control access increases the
security risk if the password is compromised.
(2)
Once a password is set, you can only change it. You cannot clear a password unless you perform a restore
operation or return the terminal to the out-of-box condition. See
Returning to the Out-of-box Condition on page
112 and Restoring the Terminalon page 113 for instructions.
IMPORTANT
Changing any VNC setting will terminate the current VNC
connection to the terminal. For example, if you are connected to
the terminal in control access and change the access to
view-only, the VNC connection will terminate and the next time
you connect to the terminal you will be in view-only access.
IMPORTANT
When you update the terminal firmware, the VNC password
and settings will be cleared and reset to their default
configuration.
