Using Simple Instruction Set (SIS

™

) Commands

Simple Instruction set (SIS) commands can be entered on your PC to ﬁ nd out more

information about the DVCM 50.

Host-to-DVCM communications

SIS commands consist of one or more characters per ﬁ eld. No special characters

are required to begin or end a command sequence. When the DVCM determines

that a command is valid, it executes the command and sends a response to the host

device. All responses from the controller to the host end with a carriage return and

a line feed (CR/LF = ), which signals the end of the response character string. A

string is one or more characters.

DVCM-initiated messages

When a local event such as a front panel (or Extron switcher front panel) selection

or adjustment takes place, the DVCM responds by sending a message to the host.

No response is required from the host. The DVCM-initiated messages are listed

here (underlined).

The DVCM sends the copyright message when it ﬁ rst powers on.

Error responses

When the DVCM receives a valid SIS command, it executes the command

and sends a response to the host device. If the DVCM is unable to execute the

command because the command is invalid or it contains invalid parameters, it

returns an error response to the host.

The error response codes and their descriptions are as follows:

E10 – Invalid command

E13 – Invalid value (Number is out of range.)

E14 – Invalid for this conﬁ guration
