UDM-0808-SIG SEND COMMANDs (Cont.)
"'?A'"
Returns connection
status for audio
outputs in the Hub.
Syntax:
SEND_COMMAND <DEV>, "'?A<O#>'"
Variables:
• O# = output port number:
1-8 = Outputs 1-8 - a value of 0 or "ALL" means all outputs
Example 1:
SEND_COMMAND dvUDM,"'?A'"
Returns which audio inputs are connected for all outputs.
Example 2:
SEND_COMMAND dvUDM,"'?A1"
Returns which audio input is connected to output 1.
The returned string is of the form
AO#-II#
Where:
• O# is the queried output port number
• I# is the connected input number (zero if disconnected)
For example:
A6-I3
Indicates that audio output 6 was connected to input 3.
"'CI"'
Connect video and
audio inputs to
outputs.
Syntax:
SEND_COMMAND <DEV>,'"CI<I#>O<O#>"'
Variables:
• I# = input number
1-8 = Inputs A-H - a value of 0 means no input (disconnect)
• O# = output port number:
1-8 = Outputs 1-8 - a value of 0 or "ALL" means all outputs
• S# = optional sub input number (1-3) for selection of CVBS inputs
Example 1:
SEND_COMMAND dvUDM,'"CI2O4"'
Connect input B video and audio to output 4.
Example 2:
SEND_COMMAND dvUDM,'"CI3O0"
Connect input C video and audio to all outputs.
Example 3:
SEND_COMMAND dvUDM,'"C0O0"'
Disconnect all outputs from inputs.
