5.3.7 RS232 - General description when using the MAC00-B41 module
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.
Note: The basic MAC motor
does not fully support RS232
since the interface signals are
only 5V levels. See also the ba
-
sic description - Serial interface,
page 111.
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. Use the RS485 if multiple
units have to be connected at
the same time.
2: Use shielded cable.
3: Ensure that IGND (inter-
face ground) is also connect-
ed.
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 Expansion MAC00-B41 con-
nector description, page 169.
A finished RS232 cable also exist. Please see Cables for the MAC00-B41, page 171
