12.6.1.1 Cable-connected hand-held scanners on the MA 248
i
All hand-held scanners and mobile combi devices available in the Leuze electronic product
line can be used with the corresponding connection cable.
When using the MA 248
i
, the voltage supply of the hand-held scanner (5V/at 1A) can be
connected to the interface by means of a cable via the 9-pin Sub-D connector (voltage on
PIN 9). The corresponding cable is to be selected for the respective hand-held scanner and
ordered separately. The 9-pin Sub-D cable (KB JST-HS-300, part no. 50113397) is
connected to this cable, which is connected to the MA 248
i
. This cable must also be ordered
separately.
In this example, triggering occurs by means of a trigger button on the hand-held scanner.
