About This Manual

This user’s manual covers several variations of Black Box’s 8x8 and 16x16 VGA/HD matrix switches. Four configurations of the matrix are discussed in this user’ manual per the table below. Since this is an all-encompassing user’s manual, portions of this guide may not pertain to any specific unit.

AC1120A	8x8	VGA Matrix Switch With Serial Control

AC1121A	8x8	VGA & Audio Matrix Switch with IP and Serial Control

AC1122A	16x16		VGA Matrix Switch with Serial Control

AC1123A	16x16		VGA & Audio Matrix Switch with IP and Serial Control

***Upon power-up the switches output a string on their RS-232 port that identifies the unit’s capabilities such as: BBox-I-A-8-8 (I=IP port, A= Audio, 8-8 = number of inputs and outputs respectively)

1.0 General

The AC1120A through AC1123A are compact high-end matrix switches for video and audio. The matrices are used for cross-point switching of video and audio signals. The switch provides 8 or 16 video (and audio) outputs, each capable of independently displaying any of 8 or 16 inputs in any combination. Additionally, the outputs can be blanked out and/or muted. The Matrices can be used in TV broadcasting environments, multi-media conference halls, public facilities, large display projects, schools, courtrooms, and command & control centers.

The units are compatible with PC video from 640x480 to 1920x1600 or analog SD/HDTV Component Video (YPbPr) from 480i to 1080p. The Matrix can be controlled in 3 ways: manually using the buttons on the front panel, through one or two serial RS232 control ports, or remotely via IP port.
