3.6 Connecting USB devices
3.6.1 General
The 846 Dosing Interface has two USB connectors (type A sockets) for
peripheral devices with USB interfaces. The 846 Dosing Interface functions
as a USB hub (distributor) no matter how it is operated. If you wish to
connect more than two devices to the USB, you can also use an addi-
tional, commercially available USB hub.
CAUTION
If you operate the 846 Dosing Interface with the aid of the Touch Con-
trol, take care to ensure that the Touch Control is switched off when
you set up or disconnect connections between the various instruments.
If you use a PC software to control the 846 Dosing Interface, you
should exit the program before you set up or disconnect the USB con-
nections.
