HDBaseT Control Pass-Thru Ports
Input 1 HDBaseT IR/RS-232 Pass-Thru
• 3-pin terminal block for IR or RS-232.
• IR and RS-232 extensions not supported simultaneously
• Maximum supported IR burst frequency = 55kHz
• Pinout:
o Pin 1 = IR Out / RS-232 Tx Data
o Pin 2 = Ground
o Pin 3 = IR In / RS-232 Rx Data
• Corresponds with IR or RS-232 control ports of compatible KD Transmitter
o Note: If IR signal input at KD-UPS52U and output at the KD Transmitter is required, please use
KD-PS22UTx.
o KD-X4x1WUTx and KD-X3x1WUTx do not feature IR Output ports and therefore IR signals input
on this port will have no corresponding IR output port unless used with KD-PS22UTx
Output 2 HDBaseT IR In & Out Pass-Thru
• 2x 3.5mm mono
• Pinout
o Tip = Signal
o Sleeve = Ground
• IR In corresponds with IR Out port of KD-X100MRx
• IR Out corresponds with IR In port of KD-X100MRx
• Maximum supported IR burst frequency = 55kHz
Output 2 HDBaseT RS-232 Pass-Thru
• 3-pin terminal block
• Pinout:
o Pin 1 = RS-232 Tx Data
o Pin 2 = Ground
o Pin 3 = RS-232 Rx Data
• Corresponds with RS-232 control ports of KD-X100MRx
