Chapter 1. System Introduction
Before After
ST (Smart Teaching), a new generation multimedia integration system integrates VGA / AV /
Audio / Mic. signal into a digital unit and control via a sensor panel. Build-in AV VGA
matrix-switcher. It also equip with IR leaning to learn multiple AV devices such as DVD player,
VCD, etc. to replace traditional remote controls. Facilitate the teaching and presentation.
Features Sensor panel with which decreases damage to panel after long-term use. With 4 AV inputs, 2 VGA inputs. Integrate all AV devices from teacher's side and control them only via sensor panel. Support 2 VGA inputs and outputs. Transmit different source signals into designated outputs by matrix-switch function. Signal transmitted via STP CAT5 Cable optimize the output audio/video quality. Broadcast source signal to projectors. Support high resolution TFT-LCD monitor, up to 1600*1200. Real-time Broadcast

III. Installation Notice: Grounding
For the better transmitting quality and protect teacher and student’s securities, all the devices
must ground properly. Using the power cord of three strands in order to ensure all devices’
grounds are connected together through the power cord. Get together the whole grounds and
connect to earth. Make sure the grounding resistance is less than 3Ω in order to avoid the
natural short with ground directly; besides, avoid the interference. We suggest you use AC
constant voltage regulator or pure power. All the outlets have to be fixed by screws and make
sure they all connect well. Please refer to the Figure (5).
Figure (5): Power distribution and grounding

ST UUsseerr’’ss MMaannuuaall 28
Attention:
1. The ground in the classroom has to connect to earth independently. It is not allowed using
the ground from power distribution room. Be ware; avoid any type of touch between natural
and ground in anywhere. Normally, use a steel nail and copper plate to be the grounding
material and the electricity has to be grounded two meters deep. Make sure the grounding
resistance is less than 3Ω. Grounding improperly will cause interference and worsen the
qualities of video and audio.
2. Fire and natural’s outlet must design toward the same direction. Always keep them on the
fixed position. For example, if fire’s outlet is on the left side, always keep it on the left side. Do
not change it at all. If the fire and natural do not design toward the same direction, it will cause
black shaking on the screen while broadcasting.
3. Demands on Phase
Normally, all computers have to connect to the same phase power while working on the
multimedia network system in order to get a better efficiency. But if they can’t work on the
same phrase power, make sure each outlet has to meet step1 and step2 mentioned above.
Key points of power checking (Checking by multi-meter)
1. Ground check
a. Make sure the power center outlet is working and interflowing. If you use multi-outlet, make sure the copper slice inside the outlet is unloosened.
b. Turn off the main power and AVR c. Turn on the multi-meter and change to “Ω” function on rotary switch. d. Use two probes to plug in different ground outlet. (See the position C at Figure (6)) e. If the number checked from multi-meter is zero, means the power is grounded. f. Do the step D and E repeatedly until you finish all the outlet check. g. After check the outlets to be all grounded, check the main power in the classroom does
be grounded
ST UUsseerr’’ss MMaannuuaall 29
2. Phase check
a. Turn on the main power and AVR. Turn on the multi-meter and change to “voltage” function on rotary switch (at least AC 250V).
b. Use the two probes to plug in the A position of different outlets then will get a VA
(voltage).
c. Do the step again then will get a VB (voltage).
d. Take the 110V for example, if the VA equals zero and VB also equals zero that means
the two outlets have been connected correctly. But if VA and VB equal 110V that means
fire wire and natural wire are connecting inversely. If VA equals zero and VB equals 220
or vice versa that means the two outlets are in different phases.
e. Repeat the step b, c and d until finish all the outlets.
See the chart (7)
Should be 0 voltage V

the distance between two rows. The checking sequence, please refer to chart (8).
