Data Protocols
Please refer to ‘Data port User Guide’ (D11943) for details.
There are several different modes for the data ports as described below.
•
Data, Dynamic Data Channel mode (data port 1)
22
When communicating between two TANDBERG products, this protocol enables the use
of a multitude of applications such as:
•
File transfer
•
Diagnostics
•
Application sharing
•
remote control
The Codec operates as a modem according to Hayes’ commands.
•
Control mode (data port 1)
21
In this mode, the Codec can be controlled by an external user interface.
•
Modem mode (data port 1)
21
When in a call - DDC mode is activated.
When not in a call - Control mode activated.
•
T.120 mode (data port 1)
The T.120 data protocol enables systems from different manufacturers to do data
conferencing- implemented by TANDBERG in the form of the T.120 data
communication protocol (MLP).
•
Enables the provision of data conferencing capabilities within an MCU call
23
.
•
Covers many different aspects of data conferencing such as application sharing and
white boarding.
•
Makes use of MLP and hence requires a suitable application matching your data
communications requirements. TANDBERG recommends Microsoft NetMeeting
version 2.0/2.1 or Intel’s IBVC (Intel Proshare) for data conferencing.
•
Maximum bandwidth for data in this mode is 32 kbps.
Please, refer to the document ‘Data conferencing & T.120 overview’ (D10632) for
details.
•
VISCA (data port 2)
For control of cameras using VISCA control protocol.
•
AUTO (data port 2)
The auto setting will automatically set the data port 2 dependent on equipment
connected. The following equipment will be automatically identified:
•
TANDBERG W.A.V.E. camera. The command set for this camera will be activated.
•
Hayes compatible modem. The command set for Hayes will be activated.
•
Other control devices. The data port will be set to
Control
mode.
22 During the time of use, the
RS232 Screen saver connector
needs to temporarily be disconnected.
