Figure 9 Connecting USB devices
CAUTION
Switch the instrument off before connecting or disconnecting a USB
device or a USB stick.
The 877 Titrino plus can only recognize the device immediately after
switching on.
The following devices can be operated directly on the USB connector
with the 6.2151.100 adapter:
￭ USB sticks (for the backup or storing of methods)
￭ 6.2147.000 numerical USB keypad
￭ 6.2148.030 RS-232/USB Box (for connecting balances or for the
RS-232 remote control)
￭ USB hub (with or without an own power supply)
The 6.2147.000 numerical USB keypad serves for comfortable numer-
ical input and for navigating in the dialog. In addition, it provides two USB
connectors. Connect additional USB devices to the keypad.
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 877 Titrino plus has no such hub. The
6.2147.000 numerical USB keypad has a USB hub and two USB con-
nectors.
