LCD Indication

Description

Remarks

The Progress Bar in the left has 6
bars in total:

1. Once the module is powered on,
the Progress Bar will roll
circularly, indicating that the
module is starting;

2. Once the module is normally
started, the Progress Bar will
show the downlink received signal
level strength;

3. In case of failure in startup, all 6
progress bars would be lit,
flashing for alarm.

The indication range of downlink
signal strength:
0: no signal input or no signal
detected;
1 bar: -110~-101dBm ;
2 bars: -100~-91dBm;
3 bars: -90~-81dBm;
4 bars: -80~-66dBm;
5 bars: -65~-51dBm m;
6 bars: ≥-50dBm;

Descriptions on the Setting:
a. The ICS micropower unit is placed indoors, facing any zone to be covered; receiving and
transmitting antenna inside.
b. the uplink isolation between the receiving and transmitting antenna is 42dB and the downlink
isolation is 58dB, so the module’s gain can be generally set to be approx. 68dB.

The uplink and downlink indications:
The UP Arrow represents uplink and
the data on the same row is
uplink-related data;
The DOWN Arrow represents
downlink and the data on the same
row is downlink-related data;

The input power value:
The data on the previous row
represents the electric level of input
power in uplink channel;
The data on the next row represents
the electric level of input power in
downlink channel.

The gain value:
The data on the previous row
represents the set gain of uplink
channel;
The data on the next row represents
the set gain of downlink channel.

Isolation:
The data on the previous row
represents the environmental
isolation of uplink channel;
The data on the next row represents
the environmental isolation of
downlink channel.

The Progress Bar in the right has 6
bars in total:

1. For the GSM system, upon
startup of module, in the process
of frequency search, the Progress
Bar will roll circularly.

2. For the GSM system, if the
frequency search failed, flashing
for alarm would occur.

3. During the normal operation, the
number of bars indicates the
condition of current working
environment.

The condition of current working
environment:
1 bar: 19~25 dB;
2 bars: 16~20dB;
3 bars: 11~15dB;
4 bars: 6~10dB;
5 bars: 0~5dB
6 bars: ＜ 0dB

2.1 Preparation

2.2 Device Debugging
Connect the module to the power adapter, approx. 20 seconds later start up the module, then
connect USB data cable to the USB port of the computer and the overall unit and open the
ICS debugging interface.
Open the ICS debugging software (PICO_ICS_TOOL_EN.exe) interface. In case of
connection failure due to incorrect setting of serial ports, the software would pop up a dialog

box indicating connection failure. Then select the current computer’s serial port in the options

of serial port configuration. You may view the computer port in the operating sequence
(computer —— attribute —— hardware —— device manager —— port). The serial port’s

baud rate is 460800 and serial port’s configuration is shown in Figure 2.2.1. once selected

properly, you may view the monitoring interface and in case of connection failure, the basic
data of monitoring interface would be read out. Only after the serial port was properly
configured could sequent operation proceed.

Figure 2.2.1
The settings of module’s monitoring interface for reference are detailed as follows:
The following screenshot is data reading in the setting of application for reference. Please
refer to the instruction concerning the use of this interface behind each screen shot in the
configuration.

Screenshot of Downlink and Uplink Setting

Description of Basic Setting Parameters:
CH NUM: See the Specifications for the maximum number of channels supported by the overall

unit based on the practical environmental setting; Up and down the line frequency point linkage
(just Settings horizontal frequency point, ascending will automatically associated the
corresponding frequency point)

Gain: According to external isolation degree automatic Settings, the biggest gain 75 db

Output power: Module of the total output power, the default Settings for downlink 13 DBM, every
15 DBM, each channel power divide (total power divide to open each channel)

Attenuation: To set the overall unit’s gain attenuation
EN: Open and close the channel based on the number of channels used; Electromagnetic linkage
(will open channel after the uplink channel corresponding also open)
Description of Work Control Parameters:
Downlink: ON means that it is under normal operating condition;
OFF means that downlink is closed and there is no output signal from the module;
Uplink: ON means that it is under normal operating condition;
OFF means that downlink is closed and there is no output signal from the module;
ICS: ON means that the feedback inhibition function is enabled (the uplink and downlink of this
switch must be under the same condition, i.e. switch on or off simultaneously);
OFF means that the feedback inhibition function is disabled;
Up link Noise Suppression: Select Not Working;
ICS protect: Select Working.

Threshold(dB): Gain binding isolation degree value (suggest setting for 17)

Downlink and Uplink Data Reading

Description on Parameters Requiring Special Attention:

Input Power: The enabled channel’s input power value, used for indicating the power of signal

received by the donor antenna;
Isolation: The isolation between the donor antenna and the retransmission antenna;
The Overall Unit’s Actual Output Power: The module’s actual output power in total.
Machine sate: And do some monitoring parameters, the condition of LNA, the state of the PLL
System: Clock, the clock reference state, logic state of loading

4 Precautions

4.1.1 Assure the quality of signal at the location of donor antenna to the greatest extent;

4.1.2 Maintain the isolation between the donor antenna and the ICS overall unit;

4.1.3 Keep the ICS micropower unit and the antenna over 1m away from the range of

human activity as possible practically;

4.1.4 Put the micropower unit and the antenna on a higher place as possible practically;

4.1.5 When setting the interface, the uplink gain is generally 5dB less than the downlink gain

and the uplink output power is generally set to maximum.
