Operating Notes

• EDID contains the A/V capabilities of a display device in regards to video resolutions and audio formats supported. This information is used by the source device to determine the format of the A/V signal on the outputs. The GefenToolBox 4x1 Switcher for HDMI 4K x 2K incorporates advanced EDID management to ensure compatibility with all sources and display devices.
• The GefenToolBox 4x1 Switcher for HDMI 4K x 2K can detect the presence of Deep Color (12-bit signal) automatically and will disable Deep Color EDID features across all other outputs if any connected device or display is not capable of processing Deep Color. This automatic behavior ensures compatibility among all output devices in a mixed-device environment. This feature cannot be disabled.
• When powering the GefenToolBox 4x1 Switcher for HDMI 4K x 2K or if the EDID mode is changed, the switcher will undergo a momentary initialization sequence. This is normal operation and may take a few seconds.
• The best way to operate and configure this unit is to use the built-in Web interface, which can be accessed by entering the IP address of the switcher into the address bar of any Web browser. See the section RS-232 and IP Configuration for more information about this feature.

Description IP Address / Port Description IP Address / Port

IP Address	192.168.1.72	UDP Port	23
Subnet	255.255.255.0	Local UDP Port	50007
Gateway	192.168.1.254	Remote UDP IP	192.168.1.255
HTTP Port	80	Remote UDP Port	50008

1. Connect an RS-232 cable from the PC to the 4x1 Switcher for HDMI 4K x 2K. Also make sure that an Ethernet cable is connected between the switcher and the network.
2. Launch a terminal emulation program (e.g. HyperTerminal) and use the RS-232 settings listed on the previous page.

NOTE: Depending upon the network, all related IP, Telnet, and UDP settings will need to be assigned. Consult your network administrator to obtain the proper settings.

1. Set the IP address for the switcher using the #sipadd command.
2. Set the subnet mask using the #snetmask command.
3. Set the gateway (router) IP address using the #sgateway command.
4. Set the Telnet listening port using the #set_telnet_port command.
5. Set the HTTP listening port using the #set_http_port command.
6. Set the UDP remote IP address for the switcher using the #set_udp_remote_ip command.
7. Set the UDP listening port for the switcher using the #set_udp_port command.
8. Set the UDP remote port for the switcher using the #set_udp_remote_port command.
9. Reboot the switcher to apply all changes, then type the IP address that was specified in step 3, in a Web browser to access the Web GUI. Use the same IP address to Telnet to the switcher.

Wall Mounting Instructions

The 4x1 Switcher for HDMI 4K x 2K should be mounted vertically in a wall or cabinet with wood/drywall screws as shown in the diagram above.
