1. synopsis
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 *-channel *0A 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 *2V or *4V, ac or dc gm,
Periphery drive power: DC*4V or DC*2V;
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: *2K (if any specific needs, usable
a*4k);
4). data storage space: *6K (if any specific needs, usable
*2K), store the data, data is not lost power,
5). output: no.8 relay output, every road is **0V maximum
voltage output bearing, the biggest bear currents are *0A;
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
RS**2 interface, 1 RS**5 interfaces-expandable short-circuit
cap
by choice.
1 road standard RS**2 serial communication interface
(anti static *5KV impact), can be directly with the computer or
text
display peripherals like communication, Through RS**2
interface can be directly downloaded program, need not
burn
implement, convenient program modification,
upgrades,
1 road standard RS**5 communication interface (anti
static shock and lightning *5KV) can be used RS**5
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;
*0), industrial shell, dustproof, beautiful, integration
compact design, convenient installation: guide or screw
hole
installation;
*1), figuration dimension: the crust: dimensions for: **5mm x
x *0mm *0mm, Internal control board: dimensions for:
**2mm x x rounded on the *6mm,
(extended reading: JMDM series I/O industrial microcontroller
serial controller has a variety of optional:
Press the I/O points: *2/8, *6/*2, 4/*0, 4/*6, *0/*0, etc,
model respectively is: JMDM - *0DIOV2, JMDM -
*8DIOMT/MR,
JMDM - COM*0MR, JMDM - 4DI*6DO, *0DIOMR etc;
All output: JMDM - COM*0MR/MT,JMDM - COM8MR etc)
3. serial communication protocols
3.3.1 communication technology parameters:
Baud rate: ***0, 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 (*0, N, 0) E open
instructions: O (*0, N, 1) E
Explanation:
1) N value for ***8; apr.
2) brackets the 1 *0 as controller address, when only control
1 controller in the address is *0; 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 (*0,*1,0) E open instruction
format for: O (*0,*1,1) E,
2. all relays output seated or full open: the total shut: O
(*0,*0,0) E always open: O (*0,*0,1) E,
3, reads the output state: O (*0,*0,1) E command controller
returns 1 road ~ 8 of the relay of the state;
4, address setting: OA (*0) E brackets 2 digits for controller
address, usually scope: *0 ~ *9, also can special
setting
is bigger.
(2), the output state controller to send computer: O
(*0,*******0) 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 ~ **0V 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 elv control &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
