Product Description
1. synopsis
jmctrl (at) msn(dot) cn.JMDM-COM8MR is a high-reliable stability industrial-grade SCM digital and serial port controller which independent
research and development by Shenzhen jingmin digital machine Co.,Ltd. It can be used for 8-channel 10A large load
of the switch control, such as lighting, heating wire, Strong electrical switches and other high-power devices,etc.
with following characters: professional industrial-grade high-reliable anti-lightning and resistance to strong
electromagnetic and high-frequency interference of the circuit design, the circuit layout is compact and reasonable,
with excellent heat dissipation. Majority of SMD chips and electronic components and the product procedure with high
confidentiality, of reliable industrial quality and stable performance, can be competent for a variety of big
electromagnetism interfence, harsh environment industrial site, such as arc current, welding curremt, inverter of the
workplace used stability.
2. technical parameters
1). work power: the main power: the 12V or 24V, ac or dc gm, Periphery drive power: DC24V or DC12V;
2). and the Lord control chip: 8 bits high-performance single chip microcomputer with high speed and high stability FPGA
programmable array circuit
3). program storage space: 32K (if any specific needs, usable a64k);
4). data storage space: 16K (if any specific needs, usable 32K), store the data, data is not lost power,
5). output: no.8 relay output, every road is 220V maximum voltage output bearing, the biggest bear currents are 10A; Adopt
unique high frequency signal output filter circuit prevent contacts unshaven, improve the relay longevity, Every road
relays are drawn a normally-on point and often close point, can control group 8 different voltage switch, Every road
relays have patch type high brightness LED lamp shows relay working condition,
6). precise control of time: take system clock, can pass the programming year, month, day, hour, minutes and seconds system
time calculations; etc.
Stability of the system: adopting enable internal watchdog and strict high-frequency filter character, make a system is
stable and reliable, since the launch of time in 1ms crashed within;
7). 2 kinds of communication mode (interface) optional: 1 RS232 interface, 1 RS485 interfaces-expandable short-circuit cap
by choice.
1 road standard RS232 serial communication interface (anti static 15KV impact), can be directly with the computer or text
display peripherals like communication, Through RS232 interface can be directly downloaded program, need not burn
implement, convenient program modification, upgrades,
1 road standard RS485 communication interface (anti static shock and lightning 15KV) can be used RS485 communication,
8), controller working state instructions: 2 LED lights display;
9), two dial the code switch: according to procedures need to set the program state or procedure parameters;
10), industrial shell, dustproof, beautiful, integration compact design, convenient installation: guide or screw hole
installation;
11), figuration dimension: the crust: dimensions for: 145mm x x 90mm 40mm, Internal control board: dimensions for:
122mm x x rounded on the 86mm,
(extended reading: JMDM series I/O industrial microcontroller serial controller has a variety of optional:
Press the I/O points: 12/8, 16/12, 4/20, 4/16, 20/20, etc, model respectively is: JMDM - 20DIOV2, JMDM - 28DIOMT/MR,
JMDM - COM20MR, JMDM - 4DI16DO, 40DIOMR etc;
All output: JMDM - COM40MR/MT,JMDM - COM8MR etc)
3. serial communication protocols
3.3.1 communication technology parameters:
Baud rate: 9600, Parity: no, Data bits: 8 bits, Stop bits: one.
3.3.2 communication protocols
(1), computer sent to controller:
1, N road relay output close instructions: O (00, N, 0) E open instructions: O (00, N, 1) E
Explanation:
1) N value for 2008; apr.
2) brackets the 1 00 as controller address, when only control 1 controller in the address is 00; Similarly hereinafter,
no longer etc.
3) example: serial control 1 controller of the 1st road relay output instructions are as follows:
Shut instruction format for: O (00,01,0) E open instruction format for: O (00,01,1) E,
2. all relays output seated or full open: the total shut: O (00,00,0) E always open: O (00,00,1) E,
3, reads the output state: O (00,30,1) E command controller returns 1 road ~ 8 of the relay of the state;
4, address setting: OA (00) E brackets 2 digits for controller address, usually scope: 00 ~ 99, also can special setting
is bigger.
(2), the output state controller to send computer: O (00,00000000) E
Brackets comma behind 8 digits corresponding behind 1 road ~ 8th road output points for the output state: 0, 1 have no
output for output.
4. Uses
1), can control 0 ~ 220V voltage range ac or dc executive devices such as cylinder, solenoid valve, relays, heating silk,
general motors, light bulb, LED lamp series, general motors for output load of communication, broken,
2), can realize e ontrol &high load hige;
3), a serial port remote real-time condition monitoring and control power plant, automatic flower production site workshop
etc, distal rooms equipment, lighting, audio, video, power supply, electronic access on or off, dispense manual
operation of toil, saving human cost;
4), can be used for centralized control building, advertising, arena industries such as lighting and sound and other
multimedia equipment, intelligent control appliance switches etc.
5), can be used for computer control various peripheral device switch,
6) and DCS for various shape control system, remote IO module, remote control system,
7), can be applied to various layout, architecture, Bridges and so on model control.
5. deliverly goods matters
1), the shipping list: controller, programming download line (attached), softcopies product information.
Independent control of electronic product material: KEILC software and tutorials, STC - download software, ISP product
information (example program, the description and the wiring diagram).
Product information: serial control electronic product information (pure sensitive serial monitoring software,
communication protocol, manual and the wiring diagram), PC VB source code (second development needs to use the person
can get).
2), delivery mode: express, packing standard: anti-static shockproof cartons.
6, after-sales service
1), warranty: since the date of products sold under normal use, hardware malfunction, guaranteed for one year, the guarantee
period after only charge the maintenance cost, Lifelong maintenance;
