Product Description

 1.Product’s introduction

jmctrl (at) msn (dot) cn.JMDM-COM4DOMR is a high reliability and stability industrial PC digital serial port controller which independently research and development by Shenzhen jingmin digital machine Co.,Ltd.. Can be used to the switch control of 4-channel 10A large load, the high-power devices such as lighting, heating wire, power switch, and strong-power switch. There are two kinds of working methods: independent control and serial port control. The former is the controller realized automatic independent control according to the PC program; and the latter is through computer equipment to do the PC, online by serial port sending instructions communicate with computer to realize real-time monitoring output.


2.Technical parameters and characteristics


1)Operating power: DC24V 1A (or AC18V 1A ), can customized for DC12V 1A (or AC12V 1A); the controller comes with the rectifier circuit, the input regardless of the positive and negative, so the AC and DC power supply universal.


2)8-bit high performance SCM control;


3)Two DIP switches: programming can be used as two input point to set special function, if it is can set 4 kinds of input status. Haven’t set up any functions In the Jingmin sample serial monitoring software.


4)The working status indication of the controller: two LED light to display power and operating status. 


5)4-channel relay output: Optically isolated relay output, passive dry contact form, you can directly control the maximum AC 220V voltage and DC 30V voltage; each maximum output current is 10A, the output state can be read back, back to read the agreement below; Back to read agreement as below;


6)4-channel relay output is divided into two groups, wiring respectively, each group can be used to control different loads such as contactors, a variety of lamps, electric wire, electric motors and a variety of electrical loads;


7)Communication Interface: 1 standard RS232 serial communication interface (anti-15KV electrostatic shock), can communicate with computers and the other PC; directly download the program by the RS232 interface, without burner, convenient procedures for modifying and upgrading;


8)Control distance: simple, close control requirements communicated by RS232, it is a one-to-one relationship between the computer and controller, the communication distance up to 10 m; complex, remote control needs an external RS232 to RS485 module remote monitoring communication, it is a one-to-many relationship between the controller and computer; communication distance up to about 1 km, each controller can be set to a different address, a computer can control up to 255 controllers, constitute RS485 remote monitoring system;


9)Stability of the system: relay output with high-frequency filter circuit, a very small harmonic; making the system has a very high stability and extremely long working life.


10)Dimensions: L*W*H: Shell:115mm*90mm*40mm;  internal control panel: 91mm*85mm*22mm;


3.Using instructions


3.1 Hardware connection attentions:


1. JMDM-COM4DOMR default to the 24V power supply (can also be customized to 12V), AC-DC general-purpose, regardless of positive and negative, the controller comes with a rectifier module.


2. Note that strict accordance with product instructions attached to page 2 wiring diagram : wiring instructions, wiring example diagram, connect the external digital output load, power wiring, serial line connect to the computer and controller;


3. The controller’s output use 0 ~ 220V AC and DC can be, depending on the load device’s operating voltage, the relay’s output external voltage of the controller should be careful to match with the corresponding external input and output devices. [Please note that: Each load should not exceed 220V * 10A! Or they will burn the relay.


3.2 working mode


 3.2.1 Independent control mode:


 1. To open the electronic version of the technical information supplied with the product: product information, programming software, download software, read again the technical information;


2, According to the instructions accompanying wiring diagram to connect the serial communication line between the computer and controller;


 3, Install the Keil C programming software supplied with the product;


4. In the KEIL C software to open the controller C51 sample programs, the use of input and output library functions to write the single-chip C language process


 5, Compiler and download: This program compiles, use the STC-ISP downloads software to download to JMDM-COM4DOMR controller; General chip model is STC11F04E, specific to open the shell to see the chip model.


6. Wiring: Double-check the correct and connect the power supply of the controller; connected external output signal can be independent achieve the output logic and timing control.


3.2.2 Serial monitoring mode:


1. To open the electronic version of the technical information supplied with the product, read again the technical information;


2. According to the manual wiring diagram attached to the connection the wiring between the controller and equipment, computers and controllers serial (RS232 or RS485 interface) communication lines;


3. Double-check and correct, connect the power of the controller;


4. Install the sample of Jingmin serial port monitoring software: direct double-click the small bulb icon file (jingmin-monitoring serial port .exe) under the support file folder or install to double-click setup.exe of the computer PC software (installer);


5. Using Jingmin serial port monitoring software to test the basic function: choose the corresponding serial port number and the controller numbers which need to control in the monitoring interface, then can monitoring the change of 8-channel output status;


6. The secondary development of the customers: customers according the communication protocol to reference the sample VB source code, Proper motion secondary development integrated to the third party system software; or using the universal serial deb ing software, according to the communication protocol to send serial commands to the controller


7. Communication distance: 


The way of RS232 serial control range within 10 meters of one-to-one relationship between the computer and the controller; JMDM-COM4DOMR only has RS232 interface suitable for short distance communication;


RS485 way serial port control needs peripheral connect RS232 turn to RS485 module; the maximum communication distance is 1.5 KM of one–to-much relationship between the computer and controller, a computer can up to control 255 controllers, each controller can set the difference address.


8. After setting well the related parameters or executive commends by the computer, the controller can away from the computer to control according to commend before PC.


3.3 communication protocol
