DIGI-88B Summary

The Intelix DIGI-88B is an eight input by eight output HDBaseT HDMI matrix switcher. The Intelix DIGI- 88B matrix improves the ease of installation similar to previous Intelix HDMI matrix switchers.

The DIGI-88B has dual outputs on each output port, allowing the same signal to be routed to the HDMI connector and a remote destination with an HDBaseT receiver. The HDBaseT ports support 1080p HDMI video with audio, bi-directional wide-band IR, matrix control via IR, and HDCP. The matrix is HDMI compatible and supports up to 2K resolutions, Deep Color, and full 3D capabilities.

The DIGI-88B can be controlled via front panel buttons, front panel IR, external IR, remote IR through HDBaseT extenders, RS232, RS485, and Ethernet. The matrix includes a simple IR remote control to allow IR switching. This IR remote control can be learned into universal remotes and IR based control systems. The matrix also features a full command set for RS232 and Ethernet control with third party control systems.
