4.3 LASER BARCODE SCANNERS
4.3.1 Supply Capacity When Wiring Directly to AS-I Compatible Scanners
For direct wiring, power distribution is performed simultaneously for all the scanners. However
all the scanner motors start up slowly so that there is no significant peak current draw. See the
specific scanner manual for consumption data.
The maximum number of same type scanners to be supplied for direct wiring by a single PWR-
120 is shown in the table below:

The following products are also AS-I compatible:
DS5100, DM3610, SC5000
. In case of
networks using a mix of products, you must calculate the total power consumption so as not
to exceed the power limits. See the specific product reference manual in the Technical
Features chapter for consumption data.
The power supply unit is connected directly to the scanners via AS-I cabling.
