PANEL DESCRIPTIONS

1IR (Infrared) Receiver

This receiver will accept command for switching between input devices using the included RMT-4IR remote control. Line of sight must be preserved between the remote and unit for proper operation.

2Power LED Indicator

This LED will become active once the included 5V DC power supply is properly connected between the unit and an open wall power socket.

3Selected Input LED Indicator

There is a 4 LED array to indicate which source is currently selected on the 4x1 3GSDI Switcher. The currently selected input will be indicated by an active LED.

43G-SDI Input Source Selector Button

Pressing this button will manually switch between as many as four SDI sources connected on the rear of the Switcher. The inputs ports (item 5 below) can accept (up to four) 3G-SDI, HD-SDI or SDI capable devices. The selected input source is sent to the single output. Selection of input sources may also be accomplished using the included RMT-4IR remote control or via the RS-232 serial communication port.

53G-SDI Inputs 1-4

These inputs ports can accept BNC connections from (up to four) 3G-SDI, HD- SDI or SDI capable devices.

63G-SDI Output

This output will accept a single 3G-SDI, HD-SDI or SDI output device with a standard BNC connector.

7RS-232 Serial Communications Port

This port is used to control input source swithcing on the 4x1 3GSDI Switcher. Please see page 10 for complete details on the serial communication features that are used on this product.

85V DC Power Receptacle

This receptacle will require power from the included 5V DC power supply for proper operation. Connect the included power supply between this port and an open wall power socket.
