5. RS232 PC SERIAL INTERFACE
The instrument has RS232 PC serial interface via a 3.5
mm terminal ( 3-13, Fig. 1 ).
The data output is a 16 digit stream which can be
utilized for user's specific application.
A RS232 lead with the following connection will be
required to link the instrument with the PC serial port.
Meter PC
(3.5 mm jack plug) (9W 'D" Connector)
Center Pin..............................
.
Pin 4
Ground/shield........................Pin 2
Pin 5
The 16 digits data stream will be displayed in the
following format :
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
12

Each digit indicates the following status :
D15 Start Word
D14 4
D13 When send the upper display data = 1
When send the lower display data = 2
D12 & D11 Annunciator for Display
= 01℃= 02℉m/S = 08
km/h = 10 mph = 12 knot = 09
FPM = 11 %RH = 04 dB = 17
LUX = 15 Ft-cd = 16
D10 Polarity
0 = Positive 1 = Negative
D9 Decimal Point(DP), position from right to the
left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
D8 to D1 Display reading, D8 = MSD, D1 = LSD.
For example :
If the display reading is 1234, then D8 to
D1 is : 00001234
D0 End Word
