(Compatible with 3G-SDI and 3G/HD/SD automatic switching) In 3D assist mode, input images for the left eye (L). B SDI1 active through output terminal (BNC) This terminal outputs SDI1 input as is. C SDI2 (HD/SD) input terminal (BNC) This is the SDI input terminal. (Compatible with HD/SD automatic switching) In 3D assist mode, input images for the right eye (R). D SDI2 active through output terminal (BNC) This terminal outputs SDI2 input as is. • When this output is used to daisy-chain*1 multiple moni- tors, 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 VIDEO OUT terminal, the VIDEO 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 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 cannot easily be pulled out. • A loop-through connection using the RS-485 input and output terminals allows operation of multiple monitors (up to 32 monitors). • Connect a terminator (120 Ω) between the first and second pin of the RS-485 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 the GPI input terminal. 8 RS-232C input terminal (D-SUB, 9 pins) External control is possible by using an RS-232C signal • Use shielded cable for making connections to an RS-232C input terminal. 13
