Design with RS232 interface
Apart from the serial interface the connector X13 of the ECOVARIO®
114 D provides two capture inputs with RS422 signal transmission for
rapid event capture.
Alternatively to the USB interface, via the RS232 interface a PC can be
connected for setting the parameter of the ECOVARIO® 114 D. How
to set the parameters of the RS232 interface is described in the manual
„Object Dictionary ECOVARIO®, ECOSTEP®, ECOMPACT®, ECO-
MiniDual“.
For RS232 communication with
ECOVARIO® 114 D a 3-core connection to
the host is needed. Th e connector X13 of the
ECOVARIO® 114 D is designed in a way
that a 1:1 standard cable for communication
with a COM port (9-pole Sub-D connector)
can be used. Transmitter and receiver of the
ECOVARIO® 114 D meet the specifi cations
of EIA-232E and CCITT V.28 and are EMC-
protected according to IEC 61000-4-2.
Th e communication protocol allows net-
work operation of up to 126 ECOVARIO®
units as slaves in a mono master network.
For this option a ring structure of the RS232
network according to the scheme in fi g. 6.29
is necessary.
