DB15 connector
Audio input: Audio: DB15 connector (with 2 rows of pins) for audio input and a loop output at the sender. The audio is extended to a remote receiver that has both line as well as powered outputs (for driving passive speakers). The DB15 audio I/O not only allows Interface with line-level 3.5-mm mini stereo audio sources (using adapter cable available from Black Box), it also provides a more reliable and secure means for the audio connection with its gold-plated D-Sub connector with jack screws. The audio input level supports a wide range of standards; it can be amplified (for driving passive speakers), +4dBu (Pro-Audio), or 10dBv (consumer line-level).

DB9 connector
RS-232 input
USB Type B connector
DR 1 input: Along with DR2, these are two “Direct” extension USB ports. The corresponding USB port on the PC is directly extended to a remote receiver with no hubs or other functions in the path. The PC’s USB port that is extended via DR1 or DR2 behaves exactly as if it were connected directly to the target device at the remote. These “Direct” USB port extensions are perfect for high-data-rate devices, such as video cameras, storage media, printers, and chart recorders. They do not support low-speed “human interface” devices, such as keyboards or mice. Having a dedicated path from the target device to the PC ensures full channel bandwidth availability in the interface (as opposed to several devices sharing one port on the PC via a hub).

USB Type B connector
USB STD input: This is a general-purpose USB port, which goes through a hub in the sender and provides two USB local output ports. It is also extended to the remote receiver, where another hub provides the user with four USB ports. These general-purpose USB ports are labeled as KBRD 1, MOUSE 2, AUX 3, and AUX 4. They support any type of low-speed or high-speed USB devices. AUX 3 and AUX 4 are typically used for touch screen displays, but support all other USB devices as well.

ServSwitch Universal Extender 2.4.3 User I/O Connector Descriptions The sender unit has ports for connection to the PC source and features local outputs for both video ports, audio signals (with amplified audio pass-through), and a general-purpose USB port (for connection to local keyboard or pointing devices). The sender unit also has an RS232 port for bidirectional extension of RS-232 data. Both the sender unit and the receiver unit have built-in power supplies with standard IEC320 jacks (no external power bricks). The sender unit includes 6-foot (1.8-m) cables for connection to the PC (3x USB, 2x VGA, 1x DB15-3.5mm audio). The sender unit also includes a rack mountable front panel. The receiver unit includes an I/O hood cover that covers all the connections, eliminating the need for a separate utility box. Both the sender and the receiver have DB15 output connectors for the sound so that standard 4- or 8-ohm passive speakers can be directly connected at both ends. 2.5 CATx Cable Requirements Depending on the model or application, from 2 to 4 UTP (CATx) cables are needed to connect the sender unit to the receiver unit. We recommend that you use CAT6 UTP because it offers maximum extension capabilities. The unit is capable of extending all the signals to more than 400 feet (approximately 450 feet using CAT6 cables). Zero or low-skew cables are not needed since the device incorporates skew correction on both video channels.

Figure 4-2 Controls and indicators on the receiver unit’s front panel
The receiver unit can be operated in two different modes: RUN mode and CAL (calibrate) mode. In the run-mode, all LEDs and buttons for video adjust are off. In CAL mode, the unit should turn on the specific video adjust LEDs to indicate the previous selection in this mode, such as channel selection A or B, HF gain, or align mode. There are two ways to get into the calibrate-mode to adjust the video. The first and recommended method is to use the VIDEO ADJUST switch on the sender unit and set it to CAL, which puts the receiver unit in the calibrate mode and also activates a test pattern. The receiver unit stays in this calibrate mode until the VIDEO ADJUST switch is set back to RUN. The other way to enter the calibrate mode is to hold down the SELECT button for three seconds at the receiver unit; in this case, the test pattern will not be displayed as output. If there is no user activity on the front panel for one minute, the receiver unit will time out and switch back to the RUN mode. NOTE: You can use the VIDEO ADJUST switch on the sender unit to quickly put the receiver unit in the calibrate-mode (Video Adjust LEDs on the receiver unit front panel are lit). The sender unit also generates a test pattern that is specifically designed for Video Calibration. The CHANNEL SELECT button is used to select either video A or video B input source to adjust. The setting for Ch A and B are independent and hence the procedure must be repeated for each of the two video screens. The UP and DN buttons are used to adjust either the high-frequency compensation (HF GAIN) or the red, green, and blue signal alignment (ALIGN). Press the UP or DN button once to increase or decrease the gain level. When holding down either the UP or DN button, the unit will automatically increase or decrease the gain level until it reaches the maximum or the minimum gain level setting. The RED, GRN, and BLU LEDs will flash when the unit’s gain level is at minimum or maximum. The UP and DN buttons can also be used to reset the HF Gain or the signal alignment. Just press them simultaneously. The SELECT button is used to select either the signal alignment (ALIGN) or the highfrequency gain (HF GAIN) adjustment.

Video Calibration
Figures 4-3 and 4-4 show how you can adjust an image to the proper resolution by using the receiver unit’s front-panel controls.
Figure 4-3 Test pattern for HF gain and skew adjustments
Select the video channel that you are going to adjust. Start by adjusting the HF gain (all three LEDs on the receiver unit lit). It’s best to start at the minimum compensation setting. To do this, either press the Down button repeatedly until the LEDs blink (indicates you are at min), or simply press both Up and Down buttons simultaneously. If the cable is long, the black-and-white horizontal lines tend to appear smeared (black smears as black, and white as white). Press the Up button repeatedly while paying particular attention after each key press to the area just to the right of the horizontal lines. Your goal is to make the transition between the horizontal black and white lines and the 50% gray background have as little smear as possible. Do not over adjust. If you do, some smear comes back, particularly near the transition but in reverse sense (white lines smear into gray as black and vice versa). The following images depict the adjustment results as seen on the screen:

Audio Adjustment
The PWR AUDIO output audio volume level can be manually adjusted by using a small flat screwdriver to turn a recessed pot clockwise for louder or counter-clockwise for softer. You cannot turn the volume all the way down. This means that even if the pot is turned fully counterclockwise, you still have some audio output.

Receiver Cover
In Figure 4-5, the location of holes where the cover screws to the receiver unit are shown with little arrows. Use four screws on the top and two screws on the bottom (hardware included).
Figure 4-5. Locations of attachment holes for screws You can use the slotted holes at either end of the unit to zip-tie the cables in place. Once the cover is firmly attached and cables zip-tied in place, you can screw the entire assembly to a suitable base using the L flanges on either side of the unit. Make sure that the front panel is accessible for skew and or video adjustments as needed.

6. Troubleshooting We recommend that all products be assembled, configured and tested prior to the final installation to eliminate the possibility of problems on site. Make sure all connections to the PC and peripheral equipment are solid. Reboot the PC if any of the connections were loose because this may have caused the PC to lock up. If the problem is related to video, check the function and calibration by placing the unit in Calibration mode using the switch on the sender unit. If the image on the display is not centered properly, use the LCD’s on screen display to do an Auto Adjust Image. If you cannot troubleshoot the setup, note all pertinent symptoms and make a list of any other equipment used in the setup. WARNING: The units contain hazardous voltages. There are no user-serviceable parts inside. Do not open or try to repair the unit yourself. There is no customer-repairable item in the unit, and you will void the warranty. Contact Black Box Technical Support at 724-746-5500 or
[email protected]. If there is a problem with USB devices, check the state of the LED’s on the front panel of the each unit. These LED’s pertain to USB links. The General purpose USB (STD) link light should be on if proper connection is made between the sender and the receiver units. The Data LED lights if connection to PC is made and a device is plugged into one of the STD USB ports on the receiver unit. The DR1 and DR2 LEDs function when the sender unit is connected to the PC and the receiver unit at the remote end is connected to a USB device (such as a printer). Link and data LEDs work together. If connection to the PC of DR1 or DR2 is verified, but the Link and Data LEDs are off, unplug the corresponding device from the receiver unit, wait five seconds and plug it back in. Check the RJ-45 port connections (A to A, B to B, etc.) to make sure they are not crossed, loose, or disconnected. Use the following list to narrow your search depending on device you are having trouble with • • • •
