During transmission, takes the values -VRS232 and + VRS232 depending on data
3 RX
During reception, takes the values -VRS232 and +VRS232 depending on data

Given the presence of the RS232 standard, logic value “0” corresponds to the voltage value +VRS232 (voltage value be-
tween +3Vdc and +15Vdc) and logic value “1” corresponds to the voltage value -VRS232 (voltage value between -3Vdc
and -15Vdc.
The following picture shows an example of connection between the device and a personal computer using a 9 pin RS232
serial connector:
