Use Telnet
Telnet is
“A terminal emulation program for TCP/IP networks such as the Internet. The Telnet program runs on your computer and
connects your PC to a server on the network. You can then enter commands through the Telnet program and they will be
executed as if you were entering them directly on the server console. This enables you to control the server and
communicate with other servers on the network. To start a Telnet session, you must log in to a server by entering a valid
username and password. “
Before you start you will need to know: • Either the IP address or the DNS name of the video server.
• A username and password
Connecting to a Video server
Within Microsoft Windows click “Start” then “Run” and type “telnet <IP>”
Notice to XP users – The telnet client within XP will echo all characters to the screen, this
is not a fault with the video servers, it’s a fault with the telnet client that ships with XP. The
screen may look similar to the one below. Although very confusing the extra characters are
not sent to the video server.

Navigating
First you need to know how to navigate the telnet session. Listed below are some of the most useful commands.
DIR – list the contents of the current directory
CD - Change Directory, e.g.
CD logs , changes to the logs directory.
CD C: , changes to the C: drive
CD .. , changes to the previous directory

Once a hard drive has been cleaned then system must be reset in order for the video partitions to be rebuilt. It is important to
make sure the VIDCFG.INI file in the ETC directory of the G: drive is set correctly to enable trouble free operation.
Debug
Debug is a list of information relating to the operation of the video server. Debug is sent out via the serial port and via port
5201 and can be accessed via a telnet client.
Debug can help diagnose problems, verify alarms and show
recording status as well as many other functions.
To show debug via Telnet connect to site on port 5201, Within
Microsoft Windows click Start then Run and type TELNET <IP>
5201
In this Example we have used IP address 10.10.8.1
