polarisation and/or
termination via the external
connector
The polarity and / or termination must
be handled via jumpers in the
connection cable's male connector
(see figures 3 and 4 for examples).
2-wire RS485 interface:
figure 3A: interface with polarity and
with termination,
figure 3B: interface with polarity and
without termination,
figure 3C: interface without polarity
and with termination,
figure 3D: interface without polarity
and without termination.
4-wire RS485 interface:
figure 4A: interface with polarity and
with termination,
figure 4B: interface with polarity and
without termination,
figure 4C: interface without polarity
and with termination,
figure 4D: interface without polarity
and without termination.
NB: polarisation can be performed on
