PANEL DESCRIPTIONS 1 IR (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. 2 Power 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.
CONNECTING AND OPERATING THE 4X1 3GSDI SWITCHER How to Connect the 4x1 3GSDI Switcher 1. Connect up to four 3G-SDI, HD-SDI or SDI source devices to the 4x1 3GSDI Switcher’s inputs using user supplied cables. 2. Connect a single 3G-SDI, HD-SDI or SDI capable device to the 4x1 3GSDI Switcher’s outputs using a user supplied cable. 3. Connect the included 5V DC power supply between the 4x1 3GSDI Switcher’s power receptacle and an open wall power socket. 4.
IR REMOTE DESCRIPTION The included RMT-4IR remote control is used to switch between inputs on the 4x1 3GSDI Switcher. Only one input can be selected at a time and this input is then output to the connected SDI output device. Example: Switch to the 3G-SDI source connected to In 3. Point the Remote at the 4x1 3GSDI Switcher and press button 3 on the IR Remote Control Unit.
IR REMOTE CONFIGURATION Setting the IR Remote Channel on the RMT-4IR In the event that IR commands from other remote controls conflict with the supplied IR Remote Control Unit, changing the remote IR channel will fix this issue. The IR Remote Control Unit has a bank of DIP switches for setting the IR channel. The DIP Switch bank on the IR Remote Control Unit is located underneath the battery cover.
DIP SWITCHES 4x1 3GSDI Switcher Configuration On the bottom of the unit, there is a bank of four (4) DIP switches. Each DIP switch performs a different function. 1 2 3 4 DIP 1 - Termination Mode ON - 100Ω Termination • Adds a 100Ω termination on the RS-485 line. This DIP switch should only be used when RS-485 is enabled and if the line is to be terminated, usually on the last device in the chain. OFF (default) - No Termination • For normal use and when using the RS-232 protocol.
