3)when use DC 24V or 12V 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.

3) Detectiontheinput stateof the input points: In theInput detection dialog box you can see the status of the four input points

4) Control the output states of the output points: In the output detection dialog box you can control the output state of 16 output points.

2.3 Extended functional descriptionofthe 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 RS232 communication between the computer and the controller is One-on-one relationship; The maximum communication distance is 10 meters,; For complex applications can be used RSD485 communication between the computer and the controller is one- to -many relationship; The maximum communication distance is 15 meters, Each controller can be set to a different address, a computer or master PLC can up to control 255 controllers.

Communication protocols areasfollows

Baud rate: 9600      Parity: No      Data bits: 8        Stop bit: 1

Address Setting Software; OA(00)E

2) Multiple networkconstitutealarge-scaleremotemonitoring controlsystem;

Trough the Address coding and RS454 networking, a host can address up to control 255 controllers, a computer with 255 dimming controller formed large-scale remote monitoring and control system; The distance between multiple controllers, the controller and the host can be extended through RS485 power bus (up to 1000 meters), so that the host can be placed far away from the controller, To realize the remote network control.

3) Customized demand:

According to customer's specific needs, customized to meet customer requirements of diversity, individuality, application control system functions and the PC control software, Such as timing, loop automatic control digital input and output; or programming to set the logical relationship between the input and output.

3. Performance parameters

1\ Working power: The main power: AC18V ( DC24);Peripheral drive power: DC24V or DC12V:

2 The main control chip: Eight high-performance single-chip-microcomputer;

3 Storage space; Program storage space: 32K (If there is a specific need, can use 64 K); data storage space: 16K (If there is a specific need, can use 32 K): save the date, data is not lost after power failure;

4\Input and Output: Up to 4 inputs, 16 outputs Input and output points can be customized according to customer needs. 4 opto-isolated digital inputs, NPN input forms, input current is 10 MA; of which two can be used as an interrupt source used to count, 16 opto-isolated digital outputs Eight of the path is for NPN transistor output, Output voltage is 24/12V, Maximum current is 4A, in addition, eight is a PNP transistor output, output voltage is 24V/12V, Maximum output current is 4A, The output status can be read back.

5System stability: Use Optical isolation and enable the internal watchdog and rigorous high-frequency filter characteristics, make the system working stable and reliable, the driver start-up time in less than a second time.

6 Interface: a standard RS232 serial communication interface (anti-static shock of 15V), can download program by RS232 interface directly, no need burner, Convenient the procedure to modify and upgrade, Can also write the host computer software and computer or touch screen, text display peripheral communication and so on.

7\ Working status indicator: 2 LED indicators, Two DIP switches according to the procedure need to set the state of the program or program parameters.

8Shell with screws or rail mounting, integrated compact design:

    Shell size: L * W * H: 146mm*90mm*40mm;
