INTRODUCTION
The SB-5688CK is professional 8x8 matrix routing switch.
Supporting eight (8) HDMI Inputs and (8) HDMI and (8) HDBaseT
(PoH optional via the SB-5688CAP*) Outputs. The SB-5688CK
is based on the HDBaseT standard and supports full HDMI video
resolution with embedded EDID and PoH function (optional via
the SB-5688CAP), Audio, RS-232, Ethernet and Bi-Directional IR,
all over a single CATx cable. With a signal bandwidth of 340Mhz,
so there is no signal degradation. High definition digital signals
can be selected and distributed to any (8) Inputs to (16) Outputs
simultaneously (channel outputs mirrored). The switcher is certified
as being fully CEC and HDCP 2.0 compliant, full HD 4K2K HDMI
V1.4a, 3D formats, data rates up to 6.75 Gbps. Supports UXGA/

5688CK has 1x HDMI for Input, effectively making this an 8 in x16
out switcher (same signal on both HDMI and HDBaseT outputs).
Using IR remote the switcher’s HDBaseT extender transmitter (Tx)
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. The 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-
