EAS Mono System Manual
1. System Features
EAS Mono System is a kind of EAS Sensor which integrates with the
Transmitter and the Receiver. The brand new Mono system technology
has already lead the EAS RF system to a mature time. Compared with the
original EAS system, the Mono system is excellent with its fashionable
configuration ,high performance and convenient installation.

DS1~DS8 explanation
1)DS1: indicate alarm status,flashing when detect the tag/label signal
2)DS2~DS4,for indicating noise level of the system working circumstance.
DS2~DS4 three LED all go out:little noise
DS2 lighting:Low level of noise
DS2 &DS3 lighting:Medium level of noise
DS2&DS3&DS4 all lighting:High level of noise.
When in normal status,through adjusting the VR1 to get the DS2 lighting,and
the DS3 flashing.
3)DS5 (null)
4)DS6&DS7:indicate system working status
DS6&DS7 go out:Working as a master status;
DS6 goes out and DS7 is lighting:Working as a slave status;
DS6&DS7 lighting:Function closed.
5)DS8:indicate program running,lighting when in normal status.
3.System Installation
1)System Synchronization Installation
When need to install more than one Mono sensor in a project,synchronization
connection is necessary.And the syn cable use resistance ≥ 100 Ω
twisted-pair cable, synchronized connection way refer to Picture 4. From
master signal output to slaver signal input, if you want to install one more,
connect the syn cable from the slalver signal output to other slaver signal
input.
2)Cable laying and connection
①Keep the Mono system away from these cables:network reticle;power
cable(>110VAC).The syn cable can not be crossed with other cables,else
cover the syn cable with the metallic pipe.
②The Mono system adopt the appropriative power supply,can not share
power supply with computer,display or other electricity equipment

③Due to the Mono system has double side detection effect,,articles with
label must be placed at the distance of more than 1.5m.
④Keep the Switching Power Supply away from the Mono system.(at least
2m away)
⑤The system power cable must adopt 1.5mm
2
twisted-pair shield cable.
4. System Adjustment
After installation,each Mono sensor need adjustment through communication
interface with computer .Normally adopt the RS23 2 communication interface.
1)Connection between the PC and the sensor PCB
Pic6: Connection Sketch Map
Adopt the standard COM port communication cable,connect one side of the
cable with the PC RS232 interface,and connect the other side of the cable
with the sensor PCB JP4(R S232 interface). Pl ease connect Tx&R x cable and
ground cable in corret way. After conenction ,if can not open the
communication connection,please exchange the TX&RX cable (at the
JP4)position and check again.
2)Adjustment software explanation
After correct connection as the instruction above,run the ‘Mono system
adjustment’ program:

Operation Step:
(1)Build the connection:select the corresponding ‘Com’ port and press the
‘Open’ button,’Address’ set to :255 (default).
(2)’Master/Slaver’:Select the ‘Master’,and press the ‘Set’ button.This
‘Master/Slaver’ funtion has 3 options,each means:
z ‘Close’---- DS6&DS7 both lighting,system is off working status
z ‘Slaver’----only DS7 lighting,need synchronization signal input
z ‘Master’----DS6&DS7 both no lighting,system work in normal status.
(3)’Period’:3 options:’20/40/60’;or can input a value in the
range:14~20(propositional,the default value is 16)
(4)’Gain’:the default value is 1;propositional value:1~5
(5)’Pulse’:the default value is 3(refer to the circustance condition);normally
input 3 or 4
(6)’Alarm Threshold’:the default value is 1,input range:1~3(refer to the
circustance condition)
(7)’Label speed’:the default value is 1,input range:1~5(refer to the
circumstance condition)
