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

(ASCII DEC 13)

(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).
