2. System instructions
2.1 Hardware connection Notes
1) JMDM*4DI*6DO by AC *8V power supply or DC *4V power supply,
selection of high quality power supply
2) Note the connection between strict accordance with product
instructions behind the attached wiring diagram to connect part of
the external digital input, part of the external digital output,
controller and power supply. Power wiring to be stricter; carefully
check to make sure the correct and then take, otherwise it will
burn out the controller or an external input and output
devices.
3)when use DC *4V or *2V power supply, the external input and
output of the controller to match with the corresponding external
input and output devices.
2.2 Jingmin PC serial port control software instructions
1) Install software:
Open the PC software monitoring package; Double-click
the ‘setup’ installation software finished, or double-click the
‘exe’ files in the support folder directly/
2) Select the serial number and the controller
address:
To select the serial port to operate in the serial port
selection box ( view which serial it is in the Device Manager,
Computer without serial port need to use USB to transform the
serial device and install its driver),
Select the controller to operate the serial port
selection box, when Serial port controls of one controller, select
the controller 1.

output detection dialog box you can control the output state of *6
output points.
2.3 Extended functional description of the PC software
1) Use Serial debugging aides issued a string
instruction to control I / O;
The customer may or may not use JMDM host
computer software, and the secondary development of their own
communication protocol, or use the general software, such as serial
debugging aides to send characters to control I / O; For simple
applications using the RS**2 communication between the computer and
the controller is One-on-one relationship; The maximum
communication distance is *0 meters,; For complex applications can
be used RSD**5 communication between the computer and the
controller is one- to -many relationship; The maximum communication
distance is *5 meters, Each controller can be set to a different
address, a computer or master PLC can up to control **5
controllers.
Communication protocols are as follows
