6.1.7 Data transmission protocol
The two RS232 interfaces of the 732 IC Detectors are configured as
DTE (Data Terminal Equipment) with the following technical specifica-
tions:
• Standard Data interface in accordance with EIA standard
RS 232C (DIN 66020, page 1), transmission
parameters can be set under " >CONFIG/RS
settings ", see section 4.4.2.
• Control characters C
R
DEC 13 HEX 0D
L
F
DEC 10 HEX 0A
XON DEC 17 HEX 11
XOFF DEC 19 HEX 13
• Max. line length 80 characters + C
R
L
F
• Mode Full duplex (simultaneous transmission and
receiving)
Restriction:
If data are first received by the interface, trans-
mission is not started until the receipt is at an
end.
• Cable For interconnection of the 732 IC Detector with
third-party devices, only a shielded data cable
may be used (e.g. Metrohm D.104.0201). The
cable shield must be perfectly earthed at both
devices (pay attention to current loops: always
use star earthing). Use only connectors with
sufficient shielding (e.g. Metrohm K.210.0001
with K.210.9004).
• Cable length max. ca. 15 m
