What is SmartNet?
The SmartNet systems are a combination of high quality video and audio
switches, transmitter and receiver devices designed to transmit high reso-
lution computer video and/or audio signals over Cat5 wire. AV stands for
Audio Visual and includes such signal formats as Broadcast Video (TV video
signal), Computer Video (VGA, SVGA, SXGA and etc. signals) and various
formats of Audio signals.
Why is SmartNet necessary?
Sometimes you may have numerous source devices to be displayable upon
screens. Or that AV signals need 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 in some
cases simply not practical, due to space limitations in the conduits.
The SmartNet allows the transmission of AV signals over a standard Cat5
UTP cable over distances of up to 300m with full IR or RS232 control op-
tions. The actual distance is a function of the signal resolution and cable
quality. The following is a rough guide to distance and resolution:
How does SmartNet work?
The Smart-e SmartNet systems are switch/transmitter and receiver pairs
designed to extend video, stereo audio and IR/RS232 signals over (UTP &
STP) unshielded & shielded twisted pair category 5 (Cat5) cabling. They are
supplied with a UK power supply and consist of: a transmitter with a video
input (connectors vary by model), an audio input and a Cat5 output
and; a receiver with a cat5 input and corresponding outputs. Certain
Cat5 Cable Length Maximum Recommended Resolution
150m UXGA (1600x1200)
200m HDTV (720p,1080i, 1080p)
300m SDTV, SVGA (800x600)

1. Preparing for installation
Start installation process by ensuring 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.

4. Cascading the SNX-2114 with multiple SNX-2112s
4.1 Using ‘SHIELDED’ Cat5 cable connect the Cat5 out on the SNX-
2114 to the Cat5 In on the first SNX-2112.
4.2 Repeat this step, connecting the Cat5 out on the SNX-2112s to the
Cat5 In on the following unit, for up to 32 units.
4.3 The supplied Cat5 Power Injector should be connected between
either the SNX-2114 and first SNX-2112 or, between the final SNX-
2112 and the Smart-e receiver unit. (see diagram below).
NB Units will not function unless ‘SHIELDED’ Cat5 is used to interconnect between
the SNX-2114 and SNX-2112s. However, the Cat5 from the final SNX-2112
to the receiver unit does NOT have to be shielded.

5. Configuring the Video Processing.
On the base of the unit are four switches, these are to be used to configure
the way in which the unit handles video sources. The switches functionality are
as follows:
5.1 If more than 16 units are used then the Hex Switch (see following
page) is unable to address them. To enable the addressing of units
as 17-32 then switch 1on their base should be placed to the ON
position.
5.2. Switch 2is used to enable and disable the auto-detect feature of the
units.
Switches 3 & 4 are used to determine the source priority when the auto-
detect feature is in use.
5.3 Switch 3is used to set priority to RGB 1
5.4 Switch 4is used to set priority to Y/C or RGB 2
5.5 If both switches 3& 4are set to ON - priority will be given to CVBS.
Fig. A Shows all
switches in the OFF
position,
Fig. B shows switch
1 in the ON position,
switches 2-4 in the
OFF position.

6. Allocating unique identifications to the SNX-2112s.
6.1 Using the Hex Switch on the side of the units (see diagram below),
you can provide a unique address to each unit for control purposes.
6.2 The Hex Switch has 16 unique addresses, A-F and 0-9, please
ensure that each of the units cascaded are given a different
address.
6.3 For addressing units between numbers 17 & 32 Switch 1 on the
base of the unit should be switched ON (see previous page). Units
17-32 can then be addressed in the same manner as units 1-16
above.
In Diagram to the left
the units address is set
to 9 on the Hex Switch.

4.2 Power up your computer.
4.3 Observe both transmitter and receiver power LED are ON,
and source device is switched on.
9. Preparing and connecting System CAT-5 cable
The SmartNet utilizes category 5 (CAT 5), unshielded twisted pair (UTP) cable to
transport signal between transmitter and receiver and shielded twisted pair (STP)
to transport signals between SNX-2114s and SNX-2112s..
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 estab-
lishes minimum requirements for telecommunications cabling within a commer-
cial building. The standard covers various aspects of wiring including telecommu-
nications outlets.
Following is the wiring standard for terminating CAT 5 cable using RJ 45 connec-
tor:
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
