About This Manual
This user’s manual covers several variations of Black Box’s 8x8 and 16x16
VGA/HD matrix switches. Five 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
AC1122A-RJ45 16x16 VGA to RJ45 Output 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) There is also a command
(RI) for reading the identity of the switch.
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 three ways: manually using the buttons on the front panel, through
one or two serial RS232 control ports, or remotely via IP port.
