4.3.3 General properties of the RS 232 interface
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).
