The serial interface (RS232) settings are 9600 N 8 1. The manual states that the device sends information every 2 seconds with this message format: <ISOTOPE>: <VALUE><UNIT>. For instance "I-131: 185 MBq"
The pins carry this signals
2-RXD not used
I have used an FTDI RS232 to usb converter, a raspberry model B+ and run this script with python 3.6:
Code: Select all
import serial ser = serial.Serial('/dev/ttyUSB0', 9600, timeout=1) while 1: lectura=ser.readline() print (lectura)
If I unplug the cable from the calibrator side, the output keeps coming regardless.
If change the ttyUSB0 to a file in /dev/serial/by-id that appears when I plug the usb converter the output is the same.
Googling I have found a couple threads reporting these empty b' ', but none seemed to provide a solution...
I'm a total beginner, what should I try next?
