Command Summary
Basic Commands
Input Numbering
The UDM has a flexible architecture to maximise use of the available matrix. The UDM1604 is a 16 output
port hub, with four analog input ports and four TVM input ports. Each analog input port can be used for a
variety of input types, VGA, S-Video, component and composite, and input ports are specified by a main
number, together with a sub input number if the input can be split.
The Input number is specified as follows:
If the Input is of type 1 (composite) then the Sub input field (with values 1,2,3) can further specify which of
the three composite inputs on an Input to use for this connection.
Input A would come from the 'A' labelled VGA connector or if the cascade input is selected for this input,
from the upstream hub.
Port Numbering
There are 16 output ports, numbered 1 to 16.
Connect Input to Port
Selects the input on the ports specified by the Port property, or if non zero, the port specified in the command.
