OMMUNICATIONS
EtherCAT is the open, real-time Ethernet network developed by Beckhoff based on the
widely used 100BASE-TX cabling system. EtherCAT enables high-speed control of
multiple axes while maintaining tight synchronization of clocks in the nodes. Data
protocol is CANopen application protocol over EtherCAT (CoE) based on CiA 402 for
motion control devices. More information on EtherCAT can be found on this web-site:

RS-232
C
OMMUNICATIONS
The serial port is a full-duplex,
three-wire (RxD, TxD, Sgnd) type
that operates from 9,600 to 230,400
Baud. It can be used by CME for
drive configuration and setup or by
external equipment sending ASCII
commands. The circuit shown here is
used on the EZ board and is
recommended for user's PC boards.
It converts the single-ended TTL
signals levels in the AEV into the
ANSI RS-232 levels which are the
standard for serial communications
and computer COMM ports.
