Serial Interface - JVL MAC050 User Manual

3.3
3.3.1 Interface Connection
The Controller Interface is based on an asynchronous serial interface.
3 interface signals, Rx, Tx and ground are used. The interface can be used directly with
the serial COM port of any standard PC or ePLC by using the optional cable type RS232-
9-1-MAC which has an integrated RS232 converter. Another possibility is to use one of
the expansion modules for the MAC motor which also include an RS232 and RS485 con-
verter. See also
3.3.2 RS232 Interface signal levels
Please note that the signal levels are 0 to +5V(3.3V)DC and are thus not according to
the RS232 standard which requires +/-12V nominal at the RX and TX signals. However
the protocol used is equivalent to the RS232 protocol.
If the Basic MAC motor is implemented in an OEM application where an internal proces-
sor communicates with the MAC motor, the TX and RX terminals can normally interface
directly.
