The
Modbus Address and Parity settings are used to configure the serial interface for user communications.
Valid addresses are 1 to 247. The parity setting allows the serial port to be set for Even, Odd or no parity
(None).
The Modbus Address is also used to specify the unit ID for Modbus TCP communications. Modbus TCP
communications is provided over the Ethernet interface on port 502.
The
VNC Address and Password set access rights to the MCTB VNC server. Valid addresses are from 0 to
255. The VNC password selection defines the connection mode for the server. The selections are “None” and
“VncAuth” which requires users to enter the password when connecting to the MCTB over the VNC interface.
IMPORTANT: When multiple MCTB controllers are connected to a single router (DHCP server), it is
imperative that each MCTB have a different VNC address. If multiple MCTB controllers have
the same VNC address, network errors may result causing the VNC server to shut down or
cause the MCTB
to “lock-up” and become non-responsive requiring the unit to be power cycled
in order to return to normal operation.
The
VNC Device Name field is used to enter a name (up to 35 characters) that can better identify the MCTB to
users logged into the VNC interface. The name entered here will be used on the VNC header window on a PC,
so that if multiple VNC clients are open to different systems, each one can be identified.
The
VNC Password field is used to enter the password (up to 20 characters) that a user must enter for the
VNC interface to connect to MCTB if the VNC password is enabled.
The
IP Address field is a static field that provides the IP address of the MCTB which is required for connecting
over the VNC, web and Modbus TCP server interfaces. See the following section 9.7.1 Ethernet Settings for
more information on how to adjust the device IP and other LAN information.
The
Www. (web server) pushbutton is used to enable or disable the web server interface.
The
VNC server pushbutton is used to enable or disable the VNC server interface.
The
Ethernet button is used to access the Ethernet settings screen.
NOTE: Any changes made to the above settings must be saved in order for them to take effect. When changes
are completed, press the
“Save” button. In order for any changes to the VNC server to take effect,
power must also be cycled to the MCTB. The new VNC settings will only take effect when MCTB first
boots up. Serial communication and web server settings take effect immediately upon save.
