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.
