RS232 SERIAL INTERFACE
Female RJ45 connector
J1
1 DTR
2 TX (out) During transmission, takes the values “0” and “1” depending on data
3 RX (in) During reception, takes the values “0” and “1” depending on data
4 DR
5 GND
6 DT When “1”, device is power on
7 CT
8 RTS (out) When “1”, device is ready to receive data
NOTES:
Given the presence of the RS232 standard, logic value “0” corresponds to a voltage level of between +3Vdc and +15Vdc
and logic value “1” corresponds to a voltage level of between -3Vdc and -15Vdc.

The following picture shows an example of connection between the device and a personal computer using an 8 pin
RJ45 male and a 9 pin RS232 serial connector:
