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

3. Functional description
1. JMDM-RS**2 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 (**2,1) NO.2 relay pull power; NO.*2
relay
loss of power disconnection when serial port input O
(**2,0).
3. The serial port controller can also collect the state of
the remote input point, for example, The controller sending
out
I (**4,1) through serial port means the fourth input point
have signal input, The serial port sending out O (**2 , 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 **5, the longest network reach
***0
meters;
5. The single serial port control can independently control
the ON and OFF of **-channel relay (or transistor), can
also
collect *6 input point states. Through the address coding,
under the circumstances of one second delay's permission,
a
serial port up to address and control **5 serial ports
controller, constitute a large system composed of ***0 input
points
and ***0 output points.
6. Supplying serial port communication protocol and VB
communication source procedure, Presenting VB demo program of
operating the controller through RS**2 serial port or on
behalf of the development of special procedures.
