NTo 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.

HAudio connector (MTP U R RSA SEQ and MTP U R A models only) — Connect a suitable audio device to this 5-pole captive screw connector for mono audio output.
