What is the SmartNet X+ 8x8
The SmartNet X+ range of products are designed to switch and transmit high resolution computer video
and/or audio signal over CAT-5 wire. AV stands for Audio Visual and includes such signal formats as
Broadcast Video(TV video signal), Computer Video (VGA, SVGA, XVGA and etc. signals) and various for
mats of Audio signals.
The Smartnet X+ 8x8 products provide an unprecedented range of switching and distribution equipment
for all formats of video. By combining the features of
High quality Video and Stereo Audio matrix
Signal distribution via Cat 5 cable
Interactive Infrared control and RS232 pass-through
it creates an extremely powerful and cost effective product for use in high quality Video switching,
security and data distribution. Housed in standard 19” rack mounting cases, various models are available
allowing multiple configurations and applications providing a high quality signal conversion from the
Cat 5 cable to the plasma, computer or other display device.
Why is the SmartNet X necessary?
Sometimes there is a need for the ability to switch between a selection of multiple inputs and multiple
outputs with the required AV signals able to be transmitted over distances greater than commonly
specified product limitations of 5m. In this case several choices are available, but most are expensive
and bulky, which is some cases is simply not practical, due to space limitations in the conduits. The
SmartNet X product range allows the transmission of AV signals over a standard CAT-5 UTP cable over
distances of up to 300m. The actual distance is a function of the signal resolution and a cable quality.
The following is a rough guide to distance and resolution:

How does SmartNet X+ work?
The SmartNet X and SmartLynx receivers are high resolution components of a UXGA extender system
designed for the switching and transmitting desktop computer video and stereo audio signals over (UTP)
unshielded twisted pair category 5 (CAT 5) cabling. The transmitted signals are computer video signal, an
RGBHV (Red, Green, Blue and Horizontal and Vertical Sync) analog format, and a Stereo Audio. The basic
concept behind this product is the ability to encode and decode analog signal combined with precise line
equalization and compensation.

1. Preparing for installation
Start installation process by insuring that all video displays and audio devices are compatible with the
computers being used. This is accomplished by connecting the devices directly to the computer and
checking that the devices operate as desired without the SmartNet system.
Install CAT-5 wiring between desired locations. In order to minimize system operation difficulties, avoid
routing the system cables near fluorescent lights, air conditioners, or machines that may create electrical
noise.

Installation and Operation - SmartNet X+
2. Connect Router to the signal source
The SmartNet X+ can be used to route and extend many video formats including VGA, CVBS, Y/C, YUV, RGBS
and RGBHV. All video connections are made to the router via high density 15 way sockets (standard VGA connec-
tions). For pin connection information please see relevant chapter.
If connecting a computer then:
2.1 Connect the output of the computer video card to the computer video input of the router using a
HD15 male to male cable.
2.2 Connect the output of the computer audio card to the audio input of the router using 3.5 mm audio
male to dual RCA male cable.
If connecting an AV source then:
2.3 Connect the output of the AV source to the video input of the router using a Smart-e interface cable
depending on the relevant signal format (see later for cable information).
2.4 Connect the audio output of the AV source to the audio input of the router using a dual RCA male to
male cable.
3. Connecting the RS232 control port
3.1 To allow serial commands to be routed through to a display, first connect a pin to pin serial lead be-
tween the source device (PC) and the router.
3.2 Use a ‘null-modem’ cable dB9 socket (PC end) to dB9 plug (router end). Please contact nearest
Smart-e distributor or call [phone] for serial protocol commands.

4. Controlling the SmartNet X+
4.1.Using the RS232—RS422 converter and adaptor cable provided, connect to an available serial port on
the control computer (contact nearest Smart-e distributor or call [phone] for pinout infor-
mation if not using supplied cable).
4.2.Then connect the RJ45 of the adaptor cable
into the RJ45 socket marked ’IN’ on the
front of the SmartNet X+
4.3 Additional routers units can be linked to-
gether by looping the control RJ45 sockets
using a standard Cat 5 patch cable (not a
cross-over cable).
4.4 Each router unit must have a unique ad-
dress for the serial protocol to work - this is
set by adjusting the rotary HEX switch on
the rear. There are 16 positions (0-F) allow-
ing up to 16 units to be linked together.
5. System Power up
5.1.Turn the system on by plugging in the power adapter to the SmartNet X+, if not already connected.
5.2. Power up the source devices.
5.3.Observe both transmitter and receiver power LED are ON, and computer is fully boot-up.
5.4.Observe monitors at transmitter and receiver end displaying the same data.
Using equalization adjustment (EQ) on the back of the receiver unit adjust the image to best quality (see Re-
ceiver options). This adjustment equalizes for various cable length.

6. Connecting the Infra-Red LEDs, and Infra-Red Eye for ‘Up-the-line’ control
6.1 Connect the SM-LEDs to the relevant IR jack plug (As pictured below), ensure the LED is positioned
close to the IR sensor of the device to be controlled.
6.2 Repeat for all devices to be controlled by Infra-Red.
6.3 Connect an SM-EYE to the singular IR 3.5mm minijack port on the left hand side at the rear of the
unit (As pictured below). This will enable IR control of devices at the receiver end such as amplifi-
ers, etc. An SM-LED will need to be connected to the relevant receiver and positioned close to the
IR receiver of the device to be controlled.
7. Connecting local audio on the SNX-8x8+ with local audio output option
7.1 Connect the local Audio devices (Speakers or amplifiers, etc) to the relevant 3.5mm minijack socket
on the front of the unit (As pictured below).

9. Preparing and connecting System CAT-5 cable
The SmartNet X+ utilizes category 5 (CAT 5), unshielded twisted pair (UTP) cable to transport signal between
transmitter and receiver.
CAT 5 cable is more desirable than coaxial cable due to its low cost and ease of installation. This cable is used for
LAN applications and is found in abundance, already installed, in many buildings . The category 5 is a standard
which establishes minimum requirements for telecommunications cabling within a commercial building. The stan-
dard covers various aspects of wiring including telecommunications outlets.
Following is the wiring standard for terminating CAT 5 cable using RJ 45 connector:
Pair 1 Pins 1 & 2
Pair 2 Pins 3 & 6
Pair 3 Pins 4 & 5
Pair 4 Pins 7 & 8
Connectors: RJ-45
Capacitance: 14 pf/ft (46.2 pf/m)
Conductor Gauge: 24 AWG
Impedance: 100 +/- 15 ohms

2. Setting the cable length dials
The receiver unit is preset for approximately 100m which is sufficiently accurate for most applications (if on a
cable run of < 50m adjust the dials anticlockwise to prevent sync disturbance). However, if the image does not
look sharp enough then follow the instructions below:
2.1 Load an application you intend to use that requires a high screen resolution (such as a Windows
or word processor program).
2.2 If the video is under-compensated, you will notice a black smearing on the right-hand edge of
large horizontal objects such as title bars. The degradation becomes more noticeable as length
increases.
2.3 Look at a point on the monitor where the smearing is evident. Now rotate the Green ‘EQ’ dial
clockwise until the smearing disappears and the edge becomes very bright and too sharp. At this
point and beyond the video is over-compensated (note that over-compensation of the Red
channel can cause sync disruption which can cause certain displays not to display any image).
2.4 Rotate the ‘EQ’ dial back slightly until you reach a point where the edge looks as it should be (no
smearing or over sharpness). The compensation is now adjusted correctly for the length of the
interconnection cable being used.
2.5 Repeat this for the other colour dials.
Please note that for all practical purposes cable equalisation cannot be exact – the remote image will never be
quite as sharp as the original.

3. Sync Processing & Polarity
Sync Processing
For VGA applications the Transmitter adds the Horizontal and Vertical sync pulses to the Blue and Red channels.
Since the unit has been designed for use with other types of video the Receiver provides the ability to both pass
the Red and Blue channels transparently or process them to remove the Sync Pulses. The Green channel is al-
ways transparent.
3.1 To pass video transparently for the Red and Blue channels the jumpers must be set in the +
position.
3.2 To process the video and remove the sync pulses the jumpers must be set in the - position
In the example opposite the Blue channel is set to remove sync pulses and the Red chan-
nel to pass the video transparently.
3.3 For composite video use the Green channel
3.4 For Y/C applications set the Red link to be transparent and use the Green channel for
luminance and the Red channel for Chrominance.
3.5 For YUV applications set both the Red and Blue links to transparent and use all three channels.
When switching between different video formats the SLX-RX100 can be used for VGA and compos-
ite video OR by setting the links for transparent paths the SLX-RX100 can be used for Composite
video, Y/C and YUV.
Sync Polarity
Using the Sync Polarity section of the jumper pins it is possible to set the polarity of the Horizontal and Vertical
Sync pulses.
3.3 To make the sync pulses positive going the jumpers should be set in the + position.
3.4 To make the sync pulses negative going the jumpers must be set in the – position.
In the example opposite the Horizontal Sync ( Sync) is positive going and the Vertical
sync (V Sync) is negative going

5. Setting the cable length dials
The receiver unit is preset for approximately 50m which is sufficiently accurate for most applications. However
if the image does not look sharp enough then follow the instructions below:
2.1 Whilst looking at an image on the display, preferably a long horizontal bar, adjust the CABLE
COMPENSATION dial.
2.2 Looking at the right-hand edge of the bar you will see the image change. A highlighting bright
edge means over compensation whilst a blurred dark edge means under compensation.
2.3 Adjust the dial until both effects are neutralized.
The Contrast control dial is factory per-set and usually needs no adjustment.

6. Sync Processing & Polarity
Sync Processing
For VGA applications the Transmitter adds the Horizontal and Vertical sync pulses to the Blue and Red channels.
Since the unit has been designed for use with other types of video the Receiver provides the ability to both pass
the Red and Blue channels transparently or process them to remove the Sync Pulses.
1) To pass video transparently the jumpers must be set in the Video position.
2) To process the video and remove the sync pulses the jumpers must be set in the
VGA position
In the example below the Blue and Green channels are set to remove sync pulses and the Red channel to pass
the video transparently.
