Controls and Their Functions (continued) 4 MENU button, rotary knobs (with push-on switch (PICTURE)) and RETURN/VOLUME button (→page 15) Use these buttons to display menus, select and adjust settings and perform menu selections. MENU: P ress to display the TOP MENU (main menu, FUNCTION menu and INPUT SELECT menu) or to exit from a menu. Rotary knob: Turn the knob clockwise or counterclockwise to move the cursor up or down or to change set values. Press the knob to start changing set values, to confirm them and to open submenus. RETURN: Press to return to the previous menu or cancel to recover a previously set value. When no menu is open, press the rotary knob or RETURN button to open a menu other than the TOP MENU. PICTURE: When no menu is displayed, press the rotary knob to open the picture adjusting menu. (→page 15) VOLUME: When no menu is displayed, press the RETURN but- ton to open the audio volume bar meter. (→page 15) 5 Speaker (monaural) Enables monitoring of analog AUDIO, SDI and HDMI signal inputs. • Connecting headphones to the HEADPHONES output jack turns off the speaker. 6 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 headphones.

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 the screen. • 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 also supported. When this output is used to daisy-chain*1 multiple monitors, 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. *1 Daisy-chain: 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) *2*3 IN: This is the VIDEO signal (composite signal) input terminal. OUT: This is the input signal through-out terminal. *2 Unless a cable is connected to the OUT terminal, the VID- EO IN terminal is automatically terminated at 75 Ω. Connecting a cable releases this termination. *3 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 DVI-I terminal. 4 HDMI terminal (Type A) This is the HDMI input terminal. • Use double-shielded cable for making connections to an HDMI terminal. 5 AUDIO input terminal (pin jack) This is the common audio input terminal for all video input terminals. • Use shielded cable for making connections to an AUDIO input terminal. 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 input/output terminal. • 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 terminals 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 terminal. 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 input terminal. 12
