RS232 communication Protocol
3.1 Transpor t protocols : 9600, 8, N, 1
(1) single transmit data: Data receiver(PC) transmit “R”(52H)
to DRO electronic box which well transmit data single. DRO
electronic box receive each 52H, then transmit a set of data
(current showing value).
(2) Continuous transmit data: Data receiver(PC) transmit “U”(55H)
to DRO electronic box which will transmit data continuous.
It will transmit when ever showing value changed.
(3)Stop to transmit data: DRO electronic box received 53H,
then stop to transmit data. When enter in continuous
transmit data state, it must be transmit 53H to stop it,
then can receive other orders.
3.2 ASCII code number for mat:
[Blank] X [sign-bit][Value][Value][Value][Value][Value][Decimal Point]
[Value][Value][Value][Blank] Y [sign-bit][Value][Value][Value][Value]
[Value][Decimal Point][Value][Value][Value][Blank] Z [sign-bit][Value]
[Value][Value][Value][Value][Decimal Point][Value][Value][Value]
[LF 0AH]
Decimal point position unfixed, along with set-up resolution changed,
for example:
X+1234.567 (resolution = 1,2,5,10) (Decimal point behind three figures)
X+123.4567(resolution = 0.5, 0.1) (Decimal point behind four figures)
X+123.4567 (I/M =
I
INCH I/M = M METRIC)
(Inch more than one decimal point compare Metric)
3.3 Transmission line 1.5m wire, the following is
the connection method:
