5. Communication and interfaces
5.1 RS 232 and USB interface
In order to establish communication between the UPS system and a
computer, connect the computer using a suitable data cable (cable
provided) to the RS-232 or USB interface on the UPS system (see
Chap. 8.6
Rear view
).
PLEASE NOTE
The RS-232 and USB communication interfaces cannot be
used at the same time.
The UPS system can then exchange data via the DataWatch software
(see Chap. 5.5).
The assignment of the cable connection pins for the RS-232 commu-
nications interface is shown in Figure 22, while the functions of the
connection pins can be found in Table 7
: Pin assignment for RS-232 interface
