6.4 X8: RS232 interface
Th e stepper motor amplifi er ECOSTEP®54 can be completely programmed and parameterized by a PC via
the RS232 interface. Th e connector X8 provides a pinout for direct cabling to a standard PC COM interface.
Fat drawn wires are necessary for communication, other wires are for handshaking simulations for special
PC programs. Th e transceiver inside ECOSTEP®54 meets the EIA-232E and CCITT V.28 specifi cations and
provides ESD protection to IEC1000-4-2 (801.2).
Th e communication protocol provides network operation of up to 15 ECOSTEP®54 devices working as
communication slaves in a mono master network. In that case the RS232 cabling must have a loop structure
as follows:
