SDI (HD/SD) terminal (BNC)
IN1 : This is the SDI input terminal (compatible with HD/SD automatic switching).
IN2 : This is the SDI input terminal (compatible with HD/SD automatic switching).
SWITCHED OUT : This is the active through-out terminal for the SDI input signal being displayed on thescreen.
 Active SDI through-out is only output when [SDI1] or [SDI2] is selected using the [INPUT] button. It is not
output when something other than SDI is selected. This terminal supports embedded audio.
DVI-D terminal (DVI-D)
An HDCP compliant DVI-D signal input terminal.
VIDEO terminal (BNC)
*1
IN : This is the VIDEO signal (composite signal) input terminal.
OUT : This is the input signal through-out terminal.
AUDIO IN terminal
This is the common audio input terminal for all video input terminals.
 SDI input audio is automatically selected by selecting [SDI1] or [SDI2] with [INPUT SELECT].
YP
BPR/RGB terminal (BNC)*1*3
IN : This is the YPBPR/RGB signal input terminal.
OUT : This is the input signal through-out terminal.
SYNC/HD, VD terminal (BNC)
*2
IN : This is the input terminal for external synchronizing SYNC/HD, VD signals.
OUT : This is the input signal through-out terminal.
 When using RGB signals from a PC, connect the horizontal synchronizing signal to the SYNC/HD terminal,
and the vertical synchronizing signal to the VD terminal.
GPI input terminal (D-SUB 9-pin)
External control is possible by using a GPI signal.
RS232C terminal (D-SUB 9-pin)
External control is possible by using an RS232 signal.
HEADPHONES output connector (stereo mini-jack M3)
Connect a pair of headphones to monitor the sound.
 The sound volume and sound quality will depend on the headphones.
*1 Unless a cable is connected to the OUT terminal, the IN terminal is automatically terminated at 75 Ω.
Since a connection to the OUT terminal releases the 75 Ω termination of the unit, the level of the VIDEO signal
input to the unit may become too large depending on the connected device.
*2 Unless a cable is connected to the OUT terminal, the IN terminal is automatically terminated at 1 k Ω. Making a
connection to the OUT terminal will automatically release the 1 k Ω termination. 
*3 When a device is connected to the OUT terminal, 1080P and PC input and other broadband signals may distort character outlines and other details.
