To set the connector for unidirectional communication,
see “Setting JMP1 for RS-232 communication”.
Set up the receiver for unidirectional communication
when it is to be used with an MTP DA to avoid any
RS-232/Audio detection issues.
When with an MTPX Matrix Switcher, set up the
receiver for unidirectional for transmitter to receiver
communication; otherwise it should be set to
bidirectional when using the RS-232 output insert
connections on the matrix.
