RS485 - General description when using a MAC00-Bx module
The RS485 offers more noise-
immune communication com-
pared to the RS232 interface.
Up to 32 motors can be con-
nected to the same line.
The RS485 interface in the
MAC00-B41 module is gal-
vanical isolated.
When connecting the RS485
interface to a central control-
ler, the following rules must
be followed:
1 Use twisted-pair cable
2 Use screened cable
3 Ensure that GND is also
connected.
4 Ensure that all units have a
proper connection to safety
ground (earth) in order to
refer to the same potential.
5 The last unit in each end of
the network must be termi-
nated. Note that the B1, B2
and B4, B41 modules all
contain a termination resis-
tor which can be activated.
6 Ensure that the supply lines
are connected individually
in order to minimise the
voltage drop between the
motors.
7 Master Controller RS485
interface:
If available, it is strongly rec-
ommended a type with op-
tical isolation is used.
Connectors:
To see the specific connector
pin-out please see the chapter
A finished RS485 cable also
exist. Please see
