Further information
DDC transmission with cache function
The KVM extender supports Enhanced-DDC (Enhanced Display Data Channel) to read
out the data from the monitor that is connected to the console module and transmit
them to the computer. This data includes information regarding the preferred reso-
lution and the supported monitor frequencies.
To make sure that the computer connected to the computer module
( DP1.2-Vision-IP-Fiber-CPU ) can already access the features of the remote monitor dur-
ing booting, the KVM extender contains a cache function. Even when the computer
module or the console module are switched off or the devices are not intercon-
nected, the properties of the most recently connected monitor or a default data block
are provided in the KVM extender.
The monitor’s DDC information is usually transmitted one-to-one to the computer.
Should the KVM extender determine that the display cannot be read without errors
or that the entries are invalid, the information is completed or corrected (if possible).
Determining network settings via service port
If you do not know the IP address of an already configured user or computer mod-
ule, you can use the service port of the module to find out the address.
Use any terminal emulator (e.g. Tera Term or PuTTY ) to show the log messages of
the modules.
Installing the device driver
Before establishing a connection using the terminal emulator, install the device
driver CP210x USB to UART Bridge VCP .
How to install the device driver to address the service port:
1. Use any web browser to open the website www.gdsys.com/en/start .
2. Go to More from G&D > Tools & Driver .
3. Download the device driver for the operating system installed on the computetr.
4. Execute the file and follow the instructions of the installation wizard.
NOTE: When connected to a service cable, the driver provides the Service port of a
user or a computer module as a virtual serial interface (COM port). The virtual
interface can then be selected to establish a connection using the terminal emula-
tor.
