Figure 10 Connecting the Remote Box
You can, for example, connect an 849 Level Control (fill level monitoring
in a canister) or a 731 Relay Box (switch box for 230/110 volt alternating
current sockets and low-voltage direct current outlets). The Remote Box
also has an MSB socket at which a further MSB device, 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.
3.4 Connecting USB devices
3.4.1 General
The 904 Titrando has two USB connectors (type A sockets) for peripheral
devices with USB interfaces. The Titrando functions as a USB hub (distribu-
tor) no matter how it is operated. If you wish to connect more than two
devices to the USB, you can also use an additional, commercially available
USB hub.
CAUTION
If you operate the 904 Titrando with the aid of the Touch Control, 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 904 Titrando, you should exit the program
before you set up or disconnect the USB connections.
