1, Introductions
JMDM-RS232 serial port controls relay (transistor) board is a high reliable industrial controller which independent 
research and development by Shenzhen jingmin digital machine Co., Ltd. Can be used to serial control the input and 
output of a variety of digit quantity / switch quantity signal. the Functions as follows:
1, Collecting the switch quantity signal input state through the controller, real-time displaying to the PC monitoring 
interface through the serial port.
2, Controlling the ON and OFF of the relay (or transistor) through the computer serial port, to achieve a variety of 
switch quantity control.
Having extensive application values in various types of civil and industrial occasions, Win the customers' respected 
and loved for their excellent performance and cost-effective,
Two, the Using instructions
1. Connecting the wiring between the controller and the equipment and the serial port communication wiring between the
 computer and the controller according to the wiring diagram supplied with the instructions.
2. connecting the controller power supply after careful examination and correct.
3 Installing the serial port control software and supplied with the products:
 To Double-clicking JMDM serial port controller PC procedure SETUP setup file or direct double-click JMDM serial port 
controller PC procedure SETUP support setup file.
4. Opening the PC software, can click to control input and output point.
3.  Functional description
1. JMDM-RS232 serial port controller used in the ON and OFF of the relay (or transistor).
2. After the PC (the PC or host PC) connecting to this controller through the serial port, sending a string of ASCII code 
instructions to the controller can control some (or all) relay open or close, totally unnecessary to consider the hardware 
circuit of the relay selection, drivers, etc. such as, when serial port input O (002,1) NO.2 relay pull power; NO.12 relay 
loss of power disconnection when serial port input O (012,0).
3. The serial port controller can also collect the state of the remote input point, for example, The controller sending out 
I (004,1) through serial port means the fourth input point have signal input, The serial port sending out O (012 , 0) means 
the eleventh the input point have no the signal input
4. The distance between serial port controller and control host can extend through bus 485, the longest network reach 1000 
meters;
5. The single serial port control can independently control the ON and OFF of 12-channel relay (or transistor), can also 
collect 16 input point states. Through the address coding, under the circumstances of one second delay's permission, a 
serial port up to address and control 255 serial ports controller, constitute a large system composed of 4080 input points
 and 3060 output points.
6. Supplying serial port communication protocol and VB communication source procedure, Presenting VB demo program of
 operating the controller through RS232 serial port or on behalf of the development of special procedures.
4. Performance the parameters
1. JMDM-28DIOMR/MT
1) the Working power:
JMDM-28DIOMR: AC12V or DC 12V ~ 15V;
JMDM-28DIOMT: AC 9V, peripheral drive power: AC 12V or 24v.
2) Master chip: high performance the PC;
3) Program and data storage: 64K program storage also can use to save data, the data will not lost after power failure;
4) Input: 16-channel Opto-isolated digital NPN type input, the input current is 10milliampere, 2 of them can be used for 
the interrupt source to count;
5) Output:
JMDM-28DIOMR: 12-channel Opto-isolated relay output, the output voltage is 0 ~ 220V, the maximum output current is 5A, and 
the output status can be read back;
JMDM-28DIOMT: 12-channel Opto-isolated transistor output, Open collector output form, and the output voltage is 24/12V, 
the maximum output current is 1A, and output status can be read back.
6) System stability: using Opto-isolated, enable the internal watchdog and strict high frequency filter characteristics, 
the start-up time since Crashes in less than one second.
7) Interface: a standard RS232 serial communication interface (anti-15KV static shock), can direct peripheral communication
 with computer and text display; can download procedure through RS232 interface directly, no need burner, convenient to the 
procedure modify and upgrade;
8) Working status indicator light: two LED light. LED light and DIP switch is multiplexed, also can use to set two 
parameters
9) PCB size: 155mm * 110mm;
2. JMDM--20DIOV2
1) Working power: 12V or 24V, customized according to the customers requirement, AC and DC universal, the peripheral drive
 power using 24/12V DC;
2) Master chip: high frequency the PC;
3) Procedure storage space: 32K (use 64K if there are special requirement);
4) Data storage space: 16K (use 32K if there are special requirement), saving data, the data will not lost after power 
failure;
5) Input: 12-channel Opto-isolated digital NPN input type. Input current is 10 milliampere; two of them can use for 
interrupt source to count;
6) Output:
8-channel Opto-isolated digital output, 8-channel output type can customize according to the customers requirement, 
divided into 8-channel relay output and mixed output;
8-channel relay output: it is the normally open relay output forms; withstanding the maximum working current is 5A and 
the maximum voltage is 220V, the relay is divided into 12V and 24V, Determined according to customer needs;
   Mixing output: there are 4-channel relay outputs; 4-channel transistor outputs, open-collector output form, output 
voltage is 24/12V, the maximum output current is 4A, output status can be read back.
7) The points of input and output can customize.
8) System stability:
Using Opto-isolated, enabled the internal watchdog and strict high frequency filter characteristics enabling the system
