4.3.3 General properties of the RS 232 interface
The Dosimat is configured as DTE (Data Terminal Equipment).
The RS 232 interface has the following technical specifications:
• Data interface according to the RS 232C standard, adjustable
transfer parameters, see page 18.
• Control characters: C
R
(ASCII DEC 13)
L
F
(ASCII DEC 10)
• Cable length: max. approx. 15 m
Start 7 Data Bit Parity Bit (even) 1 Stop Bit
Only a shielded data cable (for example, METROHM D.104.0201) may be used to con-
nect the Dosimat with external devices. The cable shield must be properly grounded on
both instruments (pay attention to current loops; always ground in a star-head formation).
Only plugs with sufficient shielding may be used (for example, METROHM K.210.0381
with K.210.9045).
