8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control 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.
Model AC1120A, AC1121A, AC1122A, AC1123A 1.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control 2.1.1.1 Video Inputs The video connectors on the basic unit are HD15 female. These are compatible with PC’s VGA video signal (RGBHV). The Matrix is also compatible with analog SD or HDTV signals (YPbPr) with resolutions from 480i to 1080p. To connect these types of signals to the Matrix, HD15 to 3-RCA cables may be required. Technical Note about the Video Inputs The HD15 inputs of the matrix handle only the color and sync signals.
Model AC1120A, AC1121A, AC1122A, AC1123A 2.1.2 Audio Inputs on units with RJ45 Two types of RJ45 input configurations may be possible. Please contact Black Box for availability and delivery information. The model number designates the input either as RJ45 with power or RJ45 with Audio. 2.1.2.1 RJ45 input with Video and Power The RJ45 with power units are compatible with Black Box AC504 and AC602 series of senders.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control Figure 4 – Typical balanced audio output connector The balanced audio outputs are provided on detachable screw-terminals. Mating connectors for all outputs are also provided. Technical Note about Professional Audio Output Matrices with Pro Audio option can individually adjust the audio levels at each input. Additionally they can set all the outputs to “pro line-level” of +4bBu.
Model AC1120A, AC1121A, AC1122A, AC1123A Note about Screw-Terminal Audio Outputs on units with RJ45 If the matrix has the audio switching feature, then the balanced audio outputs are always active even if the RJ45 outputs have audio. It is important to note that the channel number for the audio output is the same. So RJ45 output #1 has the same audio as screw-terminal audio output #1. 2.2.2.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control 2.4 Control Inputs The matrix can be controlled from either RS-232 or through IP. 2.4.1 Basic Unit with RS-232 Control (no IP) The AC1120A and AC1122A (without IP feature) actually have 2 separate and independent RS-232 control ports. The main RS-232 port is on a screw terminal and the auxiliary port is on an RJ45.
Model AC1120A, AC1121A, AC1122A, AC1123A control devices. Please contact Black Box if you need to draw power from this connector. Caution High-Voltage Never open the unit’s cover. Lethal voltages exists inside the unit Opening the unit also voids the warranty on the unit. The pinout for the RJ45 connector is shown in Figure 9. Figure 9 – Aux RS-232 port pinout 2.4.2 Units with IP control Models AC1121A and AC1123A are equipped with 10/100 base-T Ethernet connection and can be controlled via IP.

Model AC1120A, AC1121A, AC1122A, AC1123A … To View from output side Press and release any output button, the backlit LED of that button will light, and if that output’s video and audio are tied to one particular input, that input LED will also light. Note: If there is audio breakaway, the input LED will not be lit You can now use the and buttons to quickly go through all outputs. You can also make new ties by hitting another input button.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control At this point you have to decide if you want to view from the point of view of the input side or the output side. … To View from input side Press and release any Input button, the backlit LED of that button will light, and all the backlit LEDs for the outputs whose audio is currently tied to this input will also light up solid. You can now use the and buttons to quickly go through all inputs.
Model AC1120A, AC1121A, AC1122A, AC1123A 3.1.2.2 Making a tie by Output Video and Audio to follow each other Make sure both VID and AUD LEDs are lit, indicating that your changes will be synchronized (i.e. audio and video are from the same input). Press and release any Output button, the backlit LED of that button will light, and all the backlit LEDs for the input tied to it will light up solid. At this point, pressing any output buttons will be breaking or making connections.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control button. This will clear all ties. From here, the user can make new ties or save the blank tie over a preset that had ties in it which effectively erases that preset. 3.1.6 To reset system to factory defaults Disconnect the AC power from the unit. Press and hold the ENTER button on the front panel while plugging in AC power. Continue to hold the ENTER button until all LEDs on the front panel flash on.
Model AC1120A, AC1121A, AC1122A, AC1123A Note about VU Meter Function The front panel VU meter function is available on both the 16x16 and the 8x8 units with standard or Pro audio versions. However on the standard version the and buttons do not change the volume level. The user can do that at the source and use the matrix to monitor the level. 3.1.8.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control Figure 12 – Graph of VU dB level versus LED bar length 3.1.8.2 Adjusting the input audio Gain or attenuation Enter the audio adjustment mode as described above. Initially the audio gain level at the input is set to 0 db (gain of 1). Press and release the or button to change the gain settings. Each push is about 1dB change (see graph below).
Model AC1120A, AC1121A, AC1122A, AC1123A In adjusting the volume you want to keep the sound level as read on the VU meter at or below Position 10 (0 VU) for the loudest level at the input. When finished, press the ENTER button to save any changes or exit the audio adjustment mode.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control Note on RS-232 commands When the front panel is in use (for example to make new ties or recall presets, etc), only status request commands are accepted.
