Power Supply Connection X14
Phoenix 2-pin terminal is used to connect the power supply. An unstabilized DC voltage
between 18 V and 32 V can be applied.

Fiber-optic Ports RX (X11) and TX (X10)
Two fiber-optic ports, labeled RX and TX, must be interconnected in a ring structure
with other ibaPADU-8-M devices and the ibaFOB-card links. Connect the TX port of the
ibaFOB-card to the RX port of the first ibaPADU-8-M device in the ring. Then, connect
the TX port of this ibaPADU-8-M device to the RX port of the next ibaPADU-8-M device
in the ring. Continue until all of up to 96 ibaPADU-8-M devices are interconnected. Fi-
nally, connect the TX port of the final ibaPADU-8-M device to the corresponding RX
port of the ibaFOB-card.

Setting the Device Address with S1 and S2 Decade Switches
Using a precision screwdriver or other suitable instrument, turn the S1 decade switch to
the ones digit of the desired device address and then turn the S2 decade switch to the
corresponding tens digit of the desired device address. This defines the address of the
device within the ibaFOB-card link. (e.g. address = 45; set S1 = 4, S2=5)
