5.3 T-CPU board (05P0732)
5-20
RS-485
This is like RS-422 (balanced). It is half-duplex, and not just point-to-point but like
Ethernet since all devices (nodes) on it share the same “bus”. The driver output signal
level (loaded minimum) is +/-1.5 V.
Fig.5.3.3 shows the interface circuit on the T-CPU board.
