The rotary switch S1 is used to set the device address. Two devices can be con-
nected to a ring using the 32Mbit Flex protocol.

S2 is not used (should be zero).
Important note
Unlike other iba devices that support the 32Mbit Flex protocol, it is allowed to operate
only two ibaPQU-S systems in cascade configuration at one free 32Mbit Flex link of an
ibaFOB card because of the high sampling rate of 10 - 40 kHz and the high data volume
in the network channel of the Flex protocol.
Important note
When starting up the device for the first time, check the status signals of ibaPQU-S
(data loss etc.). If multiple signals occur, the time base of the system has to be ex-
tended.
