Enables monitoring of analog AUDIO, SDI and HDMI signal
• Connecting headphones to the HEADPHONES output jack
turns off the speaker.
HEADPHONES output jack (M3 stereo mini jack)
Allows you to connect headphones to monitor analog audio,
SDI and HDMI signal input.
• The volume and sound quality differ depending on the
1 SDI terminal (BNC)
IN1: This is the SDI input terminal (compatible with HD/SD
IN2: This is the SDI input terminal (compatible with HD/SD
SWITCHED OUT: This is the active through-out terminal for
the SDI input signal being displayed on
• Active SDI through-out is only output when [SDI1] or [SDI2]
is selected using [INPUT SELECT]. It is not output when
something other than SDI is selected. Embedded audio is
When this output is used to daisy-chain
the quality of the original signal, cable length, the number
of connected devices and other factors all come into play to
deteriorate picture quality and introduce noise.
Refers to connecting the through-out signal from a device
to the input of a second, third or more devices in a linear
series, thus using a single signal in multiple devices.
• Use a 5C-FB or equivalent cable to make connections to
an SDI terminal.
2 VIDEO terminal (BNC)
This is the VIDEO signal (composite signal) input ter-
OUT: This is the input signal through-out terminal.
Unless a cable is connected to the OUT terminal, the VID-
EO IN terminal is automatically terminated at 75 Ω. Con-
necting a cable releases this termination.
Since a connection to the through-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.
3 DVI-I terminal (single link)
This is the DVI-signal input terminal.
• Use double shielded cable for making connections to a
4 HDMI terminal (Type A)
This is the HDMI input terminal.
• Use double-shielded cable for making connections to an
5 AUDIO input terminal (pin jack)
This is the common audio input terminal for all video input
• Use shielded cable for making connections to an AUDIO
6 RS-485 input/output terminal (RJ-45)
External control is possible by using an RS-485 signal.
• Use shielded cable for making connections to an RS-485
• Make sure that the cable is fully inserted in the terminal and
that it cannot easily be pulled out.
• A loop-through connection using the RS-485 IN/OUT termi-
nals allow operation of multiple monitors (up to 32 monitors)
connected to the RS-485 IN/OUT terminals.
• Connect a terminator (120 Ω) between the first and second
pin of the OUT terminal on the last monitor in the chain.
7 GPI input terminal (D-SUB, 9 pins)
External control is possible by using a GPI signal.
• Use shielded cable for making connections to a GPI input
8 RS-232C input terminal (D-SUB, 9 pins)
External control is possible by using a RS-232C signal
• Use shielded cable for making connections to an RS-232C
