Contemporary Research 35 Display Express System Manual
Telnet Commands
As integrators have asked for tools to interact with Display Express from custom control systems, we have added
several Telnet commands to our software. More commands will be added on request from our users and control
partners.
Commands are case-insensitive, so upper or lower case may be used. Precede all commands with
‘]’.
Command Description Examples
? Displays all DX TCP
commands. ]?
EF Echo off ]EF
EN Echo on ]EN

Display Express TCP
To send commands to the Display Express server over the intranet using TCP/Telnet, do the
following:
1. For HyperTerminal and other Terminal applications, enter the IP address of the Display
Express server and 2728 as the Telnet port. Make sure the Windows Firewall exceptions
include Display Express TCP, port 2728.
2.
In a command window, type
telnet <name or IP address of Display Express server> 2728
For example, telnet CR Streams 2728. You should get a welcoming message.
3. Type Display Express TCP commands at the prompt. See above table of commands. For a
list of commands, type ‘]?’. To stop, type ‘]quit’.
SSCmd
SSCmd.exe is found in C:\Program Files\Contemporary Research\SignStream DX Service\bin. It can
be used to execute TCP-style commands in a command window or in a batch .cmd file. For
example, to send a preset to the Head End, navigate to the \bin directory in a command window,
and at the prompt type ">sscmd ]sendpreset=Turn On All Displays"
