USER MANUAL
RS-232 and Telnet Commands
The ELAN EL-4KM-VW44 can be controlled via serial and TCP/IP. The following pages list all available serial commands for the EL-4KM-VW44
Matrix. Details of RS-232 pin assignment can be found on page 5.
Commonly used Serial commands:
There are several commands that are commonly used for control and testing:-
STATUS
Status will give feedback on Matrix such as zones on, type of connection etc
PON
Power
on
POFF
Power
off
OUTxxON
(xx is the zone number you wish to turn on)
Example:- OUT01ON (This would turn output one back on)
OUTxxFRyy
(xx is the zone out, yy is the input)
Example:- OUT01FR04 (This would switch output 1 to source input 4)
Common Mistakes
• Carriage return – Some programs do not require the carriage return where as other will not work unless sent directly after the string. In the
case of some Terminal software the token <CR> is used to execute a carriage return. Depending on the program you are using this token
maybe different. Some other examples that other control systems deploy include \r or 0D (in hex)
• Spaces – ELAN commands do not require space between commands unless specified. There may be some programs that require spacing in
order to work.
- How the string should look is as follows OUT01ON
- How the string may look if spaces are required: OUT{Space}01{Space}ON
• Baud rate or other serial protocol settings not correct - please see Page 5 for Matrix settings
