8.3 RS232 interfaces
This section describes the technical data and features of the RS232
interfaces 16 16 and 17 17 of the 746 VA Trace Analyzer. You will find details
regarding attachment of instruments to these interfaces in section
3.12.
8.3.1 Features of the RS232 interfaces
The two RS232 interfaces of the 746 VA Trace Analyzer are configured as DTE
(Data Terminal Equipment) with the following technical specifications:
Standard Data interface in accordance with EIA standard RS 232C
(DIN 66020, page 1), transmission parameters can be
set on dialog page "VA TRACE ANALYZER", see section
5.3.1).
Code 8 Bit World Trade Character Set 437 (USA)
Baud rate 300, 600, 1200, 2400, 4800, 9600 (adjustable)
Handshake HWshort, HWfull, SWchar, SWline, none (details, see
section 8.3.5)
Parity even, odd, none
Stop bits 1 or 2
Data bits 7 or 8
Max. line length 80 characters + CR LF
Control characters CR Carriage Return DEC 13 HEX 0D
LF Line Feed DEC 10 HEX 0A
XON Data transmission start DEC 17 HEX 11
XOFF Data transmission stop DEC 19 HEX 13
SOH Start of Heading DEC 01 HEX 01
ETX End of text DEC 03 HEX 03
EOT End of transmission DEC 04 HEX 04
CAN Cancel DEC 24 HEX 18
Mode Full duplex (simultaneous transmission and receiving)
Restriction:
If data are first received by the interface, transmission is
not started until the receipt is at an end.
Cable For interconnection of the 746 VA Trace Analyzer 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
