Connection: Connect to RS232 socket at the back of the Rapidox using a 9 way D-
type plug. Signals are as follows:
Rapidox D-type Socket:
PC/PLC:
Pin# 2
= Data Out
Data In (RX)
Pin# 3
= Data In
Data Out (TX)
Pin# 5 = Common/Gnd --

All other pins (1,4,5,7,6,9) = Don’t care
Reading Data: Data is read using command “D”. Send the single character “D” to
the Rapidox. The Rapidox replies with one of the following responses. All valid
responses end with [CR] & [LF] (where [CR] = ASCII 13 and [LF] = ASCII 10).
Response:
!Initialising[CR][LF]
Meaning:
Rapidox is still initialising
Response:
!No sensor or sensor fault[CR][LF]
Meaning:
Sensor is not connected, or there is a fault in the sensor
Response: d2.959E+05,1.426E+01,2.000E-03,23:19:40,14/01/00,
ALM1&2,0[CR][LF]
Meaning:
“d” means data is being sent
“2.959E+05” is Oxygen reading in ppm
“,” = data separator
“1.426E+01” is Oxygen sensor reading in mV
“,” = data separator
“2.000E-03” is pressure sensor reading in bar
“,” = data separator
“23:19:40” is Rapidox time
“,” = data separator
“14/01/00” is Rapidox date
“,” = data separator
“ALM1&2” means that both alarm conditions 1 and 2 exist **
“,” = data separator
“0” is an integer indicating a sensor fault code: 0 = no faults
[CR] = ASCII 13 (Carriage Return character)
[LF] = ASCII 10 (Line Feed character)
