DVI Switch 1.0 General Thank you for purchasing Black Box AC1032A-4A 4-Port DVI Switch with Audio & Serial Control. This unit provides both a video and audio output that can be switched between four video and audio sources. This allows routing of multiple DVI equipped devices (such as PC’s) to a single DVI display (such as a plasma or LCD screen). The switcher supports single-link, DVI-D video signals at resolutions up to 1600x1200 and HDTV up to 1080i.
DVI Switch 2.0 Features 9 Clear and sharp images at resolutions up to 1600x1200 including HDTV up to 1080i 9 Hot pluggable 9 Supports the DDC2 standard for all input ports 9 HDCP & HDMI 1.
DVI Switch 3.0 Installation 3.1 Required Cables The video input cables are generally DVI male to male (customer furnished). The Audio inputs are 3.5 mm mini-stereo (customer furnished). To connect to the unit to a Serial port (such as PC’s COM1) you would need a Male/Female DB9 Serial Cable (customer furnished). All of these items are available for purchase upon request. 3.2 Inputs & Outputs The AC1032A-4A has 4 video and audio inputs labeled ‘Video 1’ through ‘Video 4’.
DVI Switch 3.
DVI Switch 4.0 Operation 4.1 Manually Switched Output The SEL1 through SEL 4 buttons are used to select between video & audio input sources of Video 1 through Video 4. A solid-on LED is used to indicate which input is selected. Holding down any of the SEL buttons for 3 seconds will blank that selected input source (and mute the audio output). The LED for that selected input will start blinking to indicate the blanking mode.
DVI Switch 4.3. Priority Selection in Auto Mode The priority of the Video 1 through Video 4 inputs can only be selected by a command through the RS232 port. This priority selection only applies to Auto mode. If a video priority is selected, the AC1032A-4A will automatically select that ‘Video' input whenever it detects the presence of a video signal at that ‘Video’ connector, regardless of what is happening at the other ‘Video’ connectors. A priority value can be set for all four ‘Video’ input connectors.
DVI Switch 4.6 RS-232 Control Port Usage The AC1032A-4A can also be controlled via a serial device. The unit operates at a baud rate of 4800 bps. From the serial port, you have full control over the operation of the switched output, mode, and priority buttons. The AC1032A-4A will output a menu to the serial port on power-up. This menu can also be displayed when the appropriate command is sent to the AC1032A-4A via the serial port.
DVI Switch 4.8 Serial Port Control Codes Control codes are 1 byte commands from an external device to the Serial Port on the AC1032A-4A. ASCII ‘1’ (Hex 31 or Decimal 49) Selects Video input #1 (immediately and unconditionally). If the unit was in AUTO mode, then MANUAL mode is selected. The device will respond with: Video 1 selected ASCII ‘2’ (Hex 32 or Decimal 50) Selects Video input #2 (immediately and unconditionally). If the unit was in AUTO mode, then MANUAL mode is selected.
DVI Switch ASCII ‘P’ or ‘p’ (Hex 50/70 or Decimal 80/112) Selects the Video Input priority. A message is displayed in the format of: Video X priority is [Y] (1-4]? Where ‘X’ is the video input (1-4) and ‘Y’ is the current priority (1-4). The user must respond within 20 seconds and with values in the range of 1-4 or the error message: Invalid input! Please select ‘Priority’ again will be displayed. If ‘0’ is input, the message No change was made will be displayed.
DVI Switch ASCII ‘A’ or ‘a’ (Hex 41/61 or Decimal 65/97) Enters Auto mode. If the unit was already in AUTO mode, the unit will respond with the message: Auto mode already selected If the unit was in MANUAL mode, the user must select the desired detection method by entering a number from 1 to 3 within 20 seconds. Values outside this range or delaying entry longer than 20 seconds will result in an error message: Invalid entry! Current detection stays the same.
DVI Switch ASCII ‘R’ or ‘r’ (Hex 52/72 or Decimal 82/114) Request the status report.
DVI Switch ASCII ‘S’ or ‘s’ (Hex 53/73 or Decimal 83/115 ) Enters Scan Mode If the unit was already in SCAN mode, the unit will respond with the message: Scan mode already selected The user must select the desired scan time by entering a number from 1 to 60 within 20 seconds. Entries outside this range or delaying entry longer than 20 seconds will result in a default setting of 5 seconds.
DVI Switch 5.0 Troubleshooting 5.1 Calling Black Box If you determine that your switcher is malfunctioning, do not attempt to repair the unit. Contact Black Box Tech. Support at 724-746-5500. Before you do, make a record of the history of the problem.
DVI Switch 5.3 Problem Solving FAQ 1. What are the Cable Length Limitations? The switcher cannot be used as an extender. Therefore it is best to plug the output of the switch directly to the display device and use input cables that are 5 meters (16 ft) maximum. In other words, try to keep the total length of cables from the video source to the box and from the box to the monitor should not exceed 16 feet. At longer distances you may experience video degradation.
