12.6.1.1 Cable-connected hand-held scanners on the MA

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 248i, 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 248i. This cable must also be ordered

separately.

In this example, triggering occurs by means of a trigger button on the hand-held scanner.
