Note
Most of the USB devices need a so-called hub in order to work cor-
rectly.
A USB hub is a distributor to which several USB devices can be connec-
ted. USB hubs are available in specialty stores in a number of different
models.
The USB (OTG) connector of the 885 Compact Oven SC has no such
hub. The 6.2147.000 numerical USB keypad has a USB hub and two
USB connectors.
The following devices can only be connected to a 6.2147.000
numerical keypad or to a USB hub:
￭ Printer (with USB connector, use the 6.2151.020 connecting cable)
￭ Barcode reader (with USB cable)
￭ Mouse (PC mouse with USB cable, for navigating in the dialog)
The following devices can only be connected to a USB hub:
￭ PC keyboard (with USB cable, for the comfortable input of letters and
numbers)
￭ Keypad with numerical keypad (with USB cable)
If you wish to connect several different instruments without own
power supply, then you must possibly use a USB hub with own power
supply (self powered). The USB (OTG) connector of the 885 Compact
Oven SC is not designed for supplying power to several devices with ele-
vated electricity requirements.
