UDM-0808-SIG SEND COMMANDs (Cont.)
"'CL'"
Connects inputs to
outputs.
Syntax:
SEND_COMMAND <DEV>, "'CL<L#>I<I#>O<O#>S<S#>'"
Variables:
• L# = level:
"ALL" - both video and audio
"VIDEO" - video only
"AUDIO" - audio only
• 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,"'CLALLI3O5'"
Connects audio & video on input C to output 5.
Example 2:
SEND_COMMAND dvUDM,'"CLALLI2O4,5,6,7,8'"
Connects audio and video on input B to outputs 4 through 8.
Example 3:
SEND_COMMAND dvUDM,'"CLAUDIOI4O1,2,6,7,8'"
Connects audio only on input D to outputs 1, 2,6, 7 and 8.
Example 4:
SEND_COMMAND dvUDM,'"CLAUDIOI0O1,4,5"'
Disconnect audio source from outputs 1,4,5.
Example 5:
SEND_COMMAND dvUDM,'"CLVIDEOI2O0"
Connect video on input B to all outputs.
"'?C'"
Returns connection
status for video
outputs in the Hub.
Syntax:
SEND_COMMAND <DEV>, "'?C<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,"'?C'"
Returns which video inputs are connected for all outputs.
Example 2:
SEND_COMMAND dvUDM,"'?C1"
Returns which video input is connected to output 1
The returned strings are of the form:
• VO#-II#
• AO#-II#
Where:
• O# is the queried output port number
• I# is the connected input number (zero if disconnected), for example
V4-I2
A4-I2
Indicates that output 4 is connected to input 2.
