8.7.4 Note for RS-485 Half Duplex (only for COM 0 in RS-485 mode)
To set an RS-485 connection in Half Duplex, add the following external loop-back:
connect pin 1 to pin 4, and pin 2 to pin 5.
Then: pins 1 and 4 are: D+ Line (A/Y); pins 2 and 5 are: D- Line (B/Z).
As factory option, the RS-485 Half Duplex mode can be set as default configuration. With this setup, the
RS-422 mode is no longer available.
