Introduction

INTRODUCTION
MICRO 8 is the state of the art miniaturized
microwave barrier and represents an absolute
innovation on the market.
Micro 8 has a diameter of only 8 cm and a very
narrow lobe aperture.
The microwave device has a high degree of
reliability and consists of a transmitting and a
receiving unit.
The technology adopted is the planar of a new
generation and military derivation,
with ultra-compact dimensions due to the
absence of the cumbersome antenna dish.
The presence of an intruder is detected using
a system of high-frequency electromagnetic
waves.
MICRO 8 is suitable for industrial, residential,
and commercial areas, prisons, military
settlements and in general in all applications
where it is also necessary to protect large
areas.
WARNINGS
•Use shielded cables.
•Power the device using the 13.8 Vdc
stabilised voltage only.
•The installation should be performed by
qualified personnel.
•MITECH is not responsible for damages
and / or barrier malfunctions
caused by incorrect installation
and / or improper use.

The microwave device consists of two TX and RX units to be positioned at opposite ends of the
protected area. The TX unit emits electromagnetic waves in the direction of the RX unit that
receives them, processes them and translates them into an electrical signal that is analyzed.
The intruder who crosses the detection area (ZR) causes a change in the signal. The intensity and
type of signal depend on the following factors,
size and mass of the intruder who crosses the ZR,
speed and time of crossing the ZR, conformation and soil conditions

Introduction
The MITECH antennas can be managed manually via the dip
-switches on both the RX and
TX modules or by using the MITECH Radar Barrier configuration proprietary program.
IMPORTANT: the modules always keep the last saved configuration in memory even in
the event of a power failure.
Installation
As standard the dip
-switches on the RX and TX modules are programmed as follows:
1.
Position the CNF dip-switch of the RX and TX module in ON mode. In this condition the led will
start to flash for a few seconds, confirming the input in configuration mode (on the TX module
the red led will remain lit, see paragraph TX Module - setting the transmission level attenuation
by 4dB on page ...).
2.
Defining the working frequency by programming the FREQ dip-switches of both modules,
the programming of the dip-switches of the RX module must be the same as that of the TX
module. If you do not want to change the frequency go directly to point 3.
3.
Orient the RX module towards the TX module in order to obtain the greater intensity of the
green RX led and the greater speed of the buzzer signal (to activate the buzzer act on the
BUZZER jumper). The turning on of the red led and the lower speed of the buzzer signal, mean
that you are moving away from the optimal position.
If necessary also act on the orientation of the TX module.
4.
At the end of the alignment if you want to keep the led on, program the led dip-switches in ON
mode on both modules.
5.
If you do not want to change other parameters and then exit the configuration mode, program
the CNF dip-switch in OFF mode on both modules, avoiding interrupting the signal and moving
the antennas.

By using the SENS LEVEL dip
-switches on the RX board , you can set the signal attenuation level.
Procedure:
1.
Enter the configuration mode (CNF in ON) and wait for the led to stop flashing.
2.
Program the two dip-switches following the combinations indicated in the following table:
3.
Exit the configuration mode by programming the CNF dip-switch in OFF mode, avoiding
interrupting the signal and moving the antenna.

By using the SENS TIME dip
-switches on the RX board , it is possible to set the duration of the signal
attenuation.
Procedure:
1.
Enter the configuration mode (CNF in ON) and wait for the led to stop flashing.
2.
Program the two dip-switches following the combinations indicated in the following table:
3.
Exit the configuration mode by programming the CNF dip-switch in OFF mode, avoiding
interrupting the signal and moving the antenna.

TX board
- 4dB transmission level attenuation setting
By using the SENS LEVEL dip
-switches on the TX board , the signal transmission level can be
attenuated by 4
dB.
Procedure:
1.
Enter the configuration mode (CNF in ON) and wait for the led to stop flashing.
2.
Program the two dip-switches in ON mode (the red led will switch off).
3.
Exit the configuration mode by programming the CNF dip-switch in OFF mode, avoiding
interrupting the signal and moving the antenna.
IMPORTANT
It is only possible to enter the configuration mode once to program the dip-switches.
In manual control mode it is not possible to make changes using the software.

MICRO 8 Installation and user manual Page 15 of 24
Procedure:
1.
Program the S/A dip-switches of the RX and TX modules in OFF mode.
2.
IMPORTANT: the CNF dip-switches of both modules must be programmed in OFF mode.
Connect the antennas (see Connection options - RS485-USB adapter).
3.
Select the MITECH radar barrier configuration program and wait a few seconds.
4.
- Select Com Ports and select the serial port on which the RS485 adapter is connected.
-
Select the communication speed according to the converter model used (standard 19200 bps).
- Select the Open Port command, wait a few seconds and then the SCAN key.
After about 16 seconds all the antennas connected to the serial port will be displayed
(see Figure 1, example of a pair of antennas connected to COM7).

The MITECH Radar Barrier Configuration program allows, via the RS485 serial connection, the maximum
and simultaneous management of 16 pairs of antennas, using only one COM port.
In case it is necessary to manage more than 16 pairs of antennas, more COM ports must be used.

Description of columns and modification of parameters
COLUMN ID
Displays the 485 serial addresses that can be controlled from a single COM.
The values entered in this column cannot be changed.
TX AND RX FREQ COLUMN
Displaying the frequency of the TX antenna and the RX antenna (range from 0 to 249 Hz) for each
connected module, 16 frequencies are set as standard.
For correct operation, the two TX and RX antennas must have the same frequency.
The program updates the values even if one of the two frequencies is changed. For example, by
changing only the freq. TX, the program also changes the freq. RX and vice versa.
To change the frequency place the mouse on the cell of the address you want to change (TX or RX)
and click once (figure 1).
Wait for the control window to open (figure 2) and enter a value between 0 and 249 and click OK
(figure 3).
In this phase the new value set on the TX
Freq and RX Freq cells will be displayed.
To save the modification, click with the mouse on the red cell of the address you are configuring
(figure 4).
TX LEVEL COLUMN
Displays the 4dB attenuation of the transmission signal for each address.
To activate or deactivate this parameter, position the mouse on the TX Level cell that you want to
modify and click once (figure 1). Wait for the activation of the curtain control (figure 2), click a second
time and select one of the two values 0
db or + 4db (figure 3).
With the value 0
db the signal is attenuated by 4 dB.
To save the modification, click with the mouse on the red cell of the address you are configuring
(figure 4).
