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 (too large)
E10 — Invalid command
E12 — Invalid output number (too large)
E13 — Invalid value (out of range)
Using the Command/Response Table
The command/response table begins on the next page. Lower case letters 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 provided on the next page and an ASCII-to-Hexadecimal
(HEX) conversion table is provided below. Command and response examples are
shown throughout the table.
Command/Response Table
Symbol Definitions:
= Carriage return/line feed
= Carriage return (no line feed)
Esc = W
X1 = Input number 01 – 04
X2
= Input number (for tie) 0 – maximum number of inputs (0=disconnected)
X3
= Output number 01 – 02
X4
= Audio gain/attenuation (-18 thru +24)
X5 = Audio gain 0dB thru 24dB (1dB/step)
X6 = Audio attenuation 1dB thru 18dB (1dB/step)
X7 = 0 – 10 (0 to 5 seconds, 0.5 seconds/step)
X9 = 0 or 1 1 = on and 0 = off
X19 = Controller software version number to second decimal place
X20 = Mute 0 = No mute, 1 = Video mute, 2 = Audio mute, 3 = Video & Audio mute
