3.5.6 Configurable Serial Port (COM3)
The configurable serial port lets the GF_VEDO HL communicate via one of the following protocols:
• default RS-485 (optically isolated, with baud rate from 9.6 kBaud to 115 kBaud)
• RS-232 (not optically isolated, with baud rate from 9.6 kBaud to 115 kBaud)
• RS-422 (optically isolated, with baud rate from 9.6 kBaud to 115 kBaud)
The protocol is configured by setting S3, S8, S9 and S10 show in figure 13 as expressed in Table 10 (see para-
graph “Access to internal system resources”).
