Extron electronic MPS 112CS manual Command/Response Table, MPS switcher error responses

MPS switcher error responses

When the MPS switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, it returns an error response to the host. The error response codes are as follows:

E01 — Invalid input channel number (too large)

E10 — Invalid command

E13 — Invalid value (out of range)

Command/Response Table

Using the command/response table

The command/response table is shown on the following pages. Lower case characters are acceptable in the command field only where indicated. Symbols are used throughout the table to represent variables in the command/response fields. Symbol definitions are shown below, and an ASCII-to-hexadecimal (HEX) conversion table is shown in figure 5-1. Command and response examples are shown throughout the command/response table.

Symbol definitions

= CR/LF (carriage return/line feed) (hex 0D 0A) = Carriage return (no line feed, hex 0D)

•= Space character

Esc	=	Escape key (hex 1B)
X1	=	Group 1 through 3 (1 = VGA, 2 = S-video, 3 = composite video)
X2	=	Inputs 0 through 4 for each group (Input 0 = off, which does not work in single switcher mode.)
X3	=	0 = off, 1 = on
X4	=	0 to 12
X5	=	1 to 66 (mic attenuation)
X6	=	-66 to +12 (dB mic gain level)
X7	=	1 = Single Switcher mode, 2 = Separate Switcher mode
X8	=	0 through 15, default = 8 (mic talk-over threshold level)
X9	=	0 through 12 (input number in Simple address)
	=	0 - 100 (program volume adjustment range)
	=	Inputs 0 through 12 for single input addressing,		= ( X1 - 1) times 4 + X2 , 0 = mute
X11			X11
	=	0 to 30 (program audio ducking level in talk over mode, 0 = off)
X12
	=	Control software version to the second decimal place
