RS232 - General description.
The RS232 interface is consid-
ered the main interface to the
motor when the motor is set
up using the MacTalk win-
dows software from a PC or
from any kind of controller us-
ing a RS232 interface.
When connecting the RS232
interface to a PC or control-
ler, the following rules must
be followed:
1 Only one motor can be
connected at the interface
line.
2 Use screened cable.
3 Ensure that GND (interface
ground) 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 RS232 interface cable
length should not exceed 10
metres.
Connectors:
To see the specific connector pin-out please see the chapter
Ex4 (basic version) connector description, page 22
