1. jmctrl (at) msn (dot) cn.JMDM-COM40MR/MT serial port brief using explanations (Use the presented of universal serial control software)
1) Connecting the wiring between the controller and equipment, the serial port communication line between the computer
and controller according to the instructions attach to the wiring diagram;
2) The default address is 00 when the serial port control one controller; 4 DIP switches need to dial up all, fully OFF
state represent the address is 00. (Remark: having marks at the DIP switch ---- arrow down means ON , that is to dial
down means the ON state, the dial on means OFF, state).
3) After careful examination and correct, connected the power supply of the controller; AC and DC universal, regardless
of positive and negative.
4) Connect the serial port control software and supplied with the products.
Method one: Double-click the small light bulb icon directly.
Path: serial port control 40-channel output PC monitoring procedure \ serial port control 40-channel output \ Support \
serial port control40-channel relay output.exe file (that is small light bulb icon).
Method two: Double-click setup.exe file, install the supplied universal serial port control software.
Path: serial port control 40-channel output PC monitoring procedure \ serial port control 40-channel output \ setup.exe
\ open the PC software can click the control output point.
2. Customers can according the communication protocol to write the PC serial port control software, through the online
download of the serial port deb ing assistant testing to sending the characters directly.
1) JMDM-COM40MR/MT serial port communication protocol with address bits
Baud rate: 9600; parity: none data bits: 8 stop bits: 1
Computer sending example:
4F 28 30 30 2c 30 30 31 2c 30 29 ASCII code;
O(00,001,0) function: the first output point of the controller’s shutdown address is 00
O(00,001,1) function: the first output point of the controller’s open address is 00
The first output point of the controller’s open address is 00 and the instructions example is: O (00, 001, 1), specify
of the communication protocol:
Send characters O ( 00 . 001 . 1 )
Function meaning instructions Communication head Controller address separator The first
channel relay separator The output state is open Communication tail
ASCII code 0x4F 0x28 0x300x30 0x2c 0x300x300x31 0x2c 0x31 0x29
2． Fully open and fully close instructions example
1. The fully open instructions example of the controller for the address is 00: O (00, 000, 1)
The fully close instructions example of the controller for the address is 00: O (00, 000,0)
The corresponding relationship between Characters and ASCII code
The corresponding ASCII code for O is: 0x4F
The corresponding ASCII code for R is: 0x52
The corresponding ASCII code for S is: 0x53
The corresponding ASCII code for P is: 0x50
The corresponding ASCII code for (is: 0x28

After-the sales the service
1) Since the date of the product sold under the normal use of the hardware failure, one year warranty, repair cost
is charged only after the warranty period. Due to natural forces and man-made damage are failures to use of the use,
inappropriate operation, and overhaul.
