Chapter 2: Overview
2. Welcome
Thank you for choosing the Black Box Dual Link DVI/USB Extender SRX units. These compact modules provide the quickest way
to extend high quality dual link DVI digital video plus USB keyboard, mouse and stereo audio with an additional two USB peripherals up to 165 feet (50 meters) away from your computer.
Thanks to our long involvement and investment in extender technology we have succeeded in overcoming the numerous problems associated with extending digital video signals. Using our proprietary transmission techniques these modules can extend all
dual link video resolutions up to 2560 x 1600. In effect, these modules can reliably transfer video rates up to 330 Mpixels per second. This is in addition to multiple USB channels plus stereo audio - all via the same single length of CAT6a or CAT7 shielded
twisted pair cabling.
The Dual Link DVI/USB Extender SRX modules have been designed to be quick to install and totally transparent in operation.

3. Installation
3.1 Mounting the modules – desk or rack
The Dual Link DVI/USB Extender SRX modules can be situated on a desk or alternatively, for larger installations, mounted within
an optional rack mount chassis.
3.1.1 Desk mount
Apply the supplied self-adhesive rubber feet to the underside of the module as shown in Figure 3-1:
Figure 3-1. Applying the supplied self-adhesive rubber feet to the underside of the module

Chapter 3: Installation
3.1.2 Rack mount
Note: The module switches are not accessible once it is inserted into the rack, therefore, check all settings before insertion.
1 Place the rack securing plate (available as a separate kit) onto the front of the module and secure it with the two countersunk
screws.
2 Orient the Dual Link DVI/USB Extender SRX module on its side so that its labeled face is the correct way up.
3 Slide the module into the required rack position. The rectangular cut-out in the front upper lip of the rack allows the two
screws on the module’s upper edge to slide through.
4 The rack mount chassis has a series of holes in its floor that are spaced to accommodate the two screws on the module’s lower
edge. Ensure that the screws correctly locate into the two holes of the chosen slot. The rack securing plate on the module
should now be flush with the front of the rack mount chassis.
5 Use the third (pan-head) screw, in the top hole of the rack securing plate to fasten the module to the rack as shown in Figure
3-2:

3.2.2 Connections at the remote module
3.2.2.1 Video connections
1 Place the remote module adjacent to the user location.
2. Connect the DVI/D lead from the video monitor to the DVI output socket of the remote module as shown in Figure 3-9:
Note: If dual link screen resolutions are
required, the DVI-D cables used at both the
local and remote modules must be dual link
types.
Figure 3-9. Attaching the DVI/D video monitor cable
3.2.2.2 USB connection
1 Connect the leads from the keyboard and mouse to two of the USB sockets on the remote module as shown in Figure 3-10:
Note: It is not important
which of the four sockets
are used.
Figure 3-10. Attaching the keyboard and mouse USB cables
IMPORTANT: The total current that may be drawn from the USB ports is 1.2A, which should be sufficient for a keyboard,
mouse (no more than 100mA each) and any two other devices (500mA maximum each). If more power for USB devices is
required, please use a powered USB hub.
2 Where other USB peripherals are also required, connect up to two other leads to the remaining USB sockets.

Chapter 4: Operation
4. Operation
4.1 General use
In use, the Dual Link DVI/USB Extender SRX modules should be transparent - the system and its peripherals should operate exactly
as normal, the only difference being that they are now up to 165 feet (50 meters) apart.
4.2 Video display (EDID) information
Extended Display Identification Data (or EDID) is an industry standard scheme which allows video monitors to declare their capabilities to the computer’s video adapter circuitry, allowing the latter to optimize their outputs accordingly. Since the widespread
adoption of the scheme, video adapters have become increasingly dependent on receiving relevant EDID information during startup, before they will output anything more than a rudimentary video signal.
Each time that the remote module is powered on, it attempts to read the EDID information from the connected DVI video monitor. If the attempt is successful, the information is transferred to the local module and stored within non-volatile memory. This is
information is then made available to the computer’s video adapter when required.
4.3 HDMI 1.3a operation
Using optional HDMI to DVI converter cables, the Dual Link DVI/USB Extender SRX modules can support HDMI video and
audio up to the 165MHz clock rate (1920 x 1080 at 60Hz, 24-bit colour).
Eight channels of HDMI audio are supported with sample sizes of 16, 20 or 24-bits at 32KHz, 44.1kHz, 48kHz, 88.2kHz,
96kHz, 176.4kHz, or 192kHz (simultaneously with the jack audio).
Note: The High-bandwidth Digital Content Protection (HDCP) and Consumer Electronics Control (CEC) schemes are not supported.

Appendix A. Troubleshooting
If you experience problems when installing or using the modules, please check through this section for a possible solution. If your
problem is not listed here and you cannot resolve the issue, then please contact Black Box technical support.
No video image is displayed on the remote monitor
• Checktheyellowindicatorsonthelocalandremotemoduleswhilenokeysarepressedonthekeyboardandnomousemovements are being made:
LOCAL: If the yellow indicator is flashing*, then the video feed to the local module is not valid. Try connecting a DVI monitor
(preferably using the same DVI link cable as used with the local module) directly to the computer and check for a correct
image.
REMOTE: If the yellow indicator is flashing*, then the video feed via the link cable is not valid. If the link cable is long, try using
a short link cable temporarily to check for basic operation.
If the yellow indicators are off, then the link cable is not properly connected.
• CheckthatboththelocalandremoteendsoftheextenderareDualLinkDVI /USBExtenderSRXvariants.ThesinglelinkDVI/
USB SRX modules are not compatible.
Only single link resolutions are displayed
• Checkthatthevideocablesconnectedtothelocalandremotemodulesarebothspecificallyduallinktypes.
Video blanking is occurring on the remote display screen
• Checkthatthecorrecttypeandlengthoflinkcableisbeingused.Pleaseseethecableadvicegivenonpage2.
* Take care not to confuse the flash and blink codes used by the yellow indicators:
•A flash is when the yellow indicator shows a regular on/off cycle every second, to warn that there’s a video feed
problem.
•A blink is when the yellow indicator is mostly on with short off periods, to confirm that a valid dual link video signal is
present.
