6.1 RS232 interfaces

732 IC Detector / 733 IC Separation Center

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

DEC 13 HEX 0D

DEC 10 HEX 0A

XON DEC 17 HEX 11

XOFF DEC 19 HEX 13

• Max. line length

80 characters + C

• 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
