Switcher error responses

When the 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, the switcher returns an error response to the host. The error
response codes are:

E01 — Invalid input channel number (out of range)
E10 — Invalid command
E11 — Invalid preset number (out of range)
E12 — Invalid output number (out of range)
E13 — Invalid value (out of range)
E14 — Invalid command for this configuration

Using the command/response table

The command/response
table begins on page 4-5.
Symbols used in the table
represent variables in the
command/response fields.
Command and response
examples are shown
throughout the table. The
ASCII to HEX conversion
table at right is for use with
the command/response
table.

With the exception of the audio input gain and attenuation commands, the SIS
commands are not case sensitive.

Symbol definitions:

= Carriage return/line feed

= Carriage return (no line feed)

= space

Esc

= Escape key

X1

= Input number

1 through 4 (MAV 44, 48) or 1 through 8 (MAV 84, 88)

X2

= Input number (for tie)

0 (untie) – maximum number of inputs

X3

= Output number

1 through 4 (MAV 44, 84) or 1 through 8 (MAV 48, 88)

Input and output numbers in commands may be entered as either 1-digit, 2-digit, or 3-digit

numbers. All input and output numbers are reported as 2-digit numbers in the response.

X4

= Numeric dB value

–18 to +10 (29 steps [dB] of audio attenuation and gain)

X5

= Input audio gain

0 through 10 (1 dB/step)

X6

= Input audio attenuation

1 through 18 (1 dB/step)

X7

= Video/audio mute

0 = no mutes

2 = audio mute

1 = video mute

3 = video and audio mute

X8

= Front panel lock, mute

1 = on

0 = off

X9

= Output gain

0 = consumer level (–10 dBV)

1 = pro level (+4 dBu)

X10

= IR receiver

1 = disable (default)

0 = enable

X11

= Preset number

01 thru 16

X12

= Controller firmware version number to second decimal place
