INTRODUCTION
The SB-5680CAK is professional 8x8 matrix routing switch. 
Supporting eight (8) HDMI Inputs, 8 Auxiliary Audio Inputs, and 
(8) HDBaseT Inputs. Supports 8 HDMI Outputs, 8 SPDIF Outputs, 
and 8 HDBaseT (PoE) Outputs. The SB-5680CAK is based on the 
HDBaseT standard and supports full resolution HDMI Video with 
embedded PoE, Audio, RS-232, Ethernet and bi-directional IR, 
all over a single CATx cable. With a signal bandwidth of 340Mhz, 
there is no signal degradation. High Definition Digital signals 
can be selected and distributed to any 8 Inputs to 16 Outputs 
simultaneously(channeloutputsmirrored). TheSwitcheriscertified 
as being fully CEC and HDCP 2.2 compliant, HDMI 4K2K V1.4a 3D 
formats, data rates up to 6.75 Gbps. Supports UXGA/WUXGA/DVI 
1920x1200 resolution to any HD displays. The SB-5680CAK has 
1x HDBaseT and 1x HDMI connector for each Input and output, 
effectively making this an 8 in x16 out switcher (same signal on 
both outputs). Using the HDBaseT Input and our HDBaseT remote 
Transmitter allows you to connect a source in a remote location. 
Likewise, the HDBaseT Output and our HDBaseT Receiver allows 
you to connect a display in a remote location. EDID management 
can be selected between eight (8) different modes. Control is 
provided via Front panel push buttons, IR remote, RS-232 or TCP/
IP (not a web-browser). An RS-232 Windows GUI interface is 
provided for matrix routing control (Windows only).
