Telnet Commands

Video Server has a Telnet daemon for only administrators to access some seldom used

functions. Using any general terminal program to connect to Video Server will prompt

the user for a password. Username is not requested here since only administrators can

access the Telnet daemon. The password is as same as that used in web access. After

logging in, type "help" for the command list. If "debug" or "dinote" is not executed,

Telnet will disconnect automatically after being idle for 1 minute.

System core debugging

General activities are recorded into SYSTEM.LOG continuously, but information about

abnormal status is not. To look deep into the core debugging information, administrators

may type the “debug” command. This will cause Video Server to start dumping the

detailed debugging information while the system is running. This is useful to examine if

any error has occurred when the system operates abnormally. Video Server will continue

to dump new messages unless the connection is broken. If Telnet is not connected, any

messages will be stored until administrators re-login.

Monitor changed status of digital inputs

Typing "dinote" will make Video Server send the current status of all digital inputs. After

that Video Server will continuously monitor DI status and send messages only when the

state has changed. For example, after typing "dinote" the terminal will display

di1=l

di2=l

di3=l

di4=l

and if DI2 changes to H, terminal will display only

di2=h

Stop information dumping

Typing "stop" will cease dumping debug information and the digital input status.

Query status of digital inputs

Typing "diquery" will display the status of all digital inputs once.

Set digital outputs

To set digital output 1 to connect NO with COMMON, type "do1=o".
