Figure 38 Connecting a remote box
You can, for example, connect an 849 Level Control Box (fill level monitor
in a waste canister) or a 731 Relay Box (switch box for 230/110 volt alter-
nating current sockets and low-voltage direct current outlets). The remote
box also has an MSB socket at which a further MSB instrument, e.g. a
dosing device or a stirrer, can be connected.
You will find precise information concerning the pin assignment of the
interface on the remote box in the appendix (see Chapter 6.1, page 46).
3.15 Connecting USB devices
Two USB connectors (Type A sockets) are available for connecting devices
with USB interfaces. The 858 Professional Sample Processor functions then
as a USB hub (distributor). If you wish to connect more than two USB
devices, you can also use an additional commercially available USB hub.
Note
When a USB device is connected, the control instrument recognizes
which device is connected. The control software automatically enters a
connected USB device into the system configuration (Device manager).
