Power Supply Connection
Phoenix 2-pole terminal is used to connect the power supply. An unstabilized DC volt-
age between 18 V and 32 V can be applied.
7.2.2
Fiber-optic Ports RX and TX
Two fiber-optic ports, labeled RX and TX, must be interconnected in a ring structure
with other ibaPADU-8-ICP devices and the ibaFOB-card links. Connect the TX port of
the iba FOB-card to the RX port of the first ibaPADU-8-ICP device in the ring. Then,
connect the TX port of this ibaPADU-8-ICP device to the RX port of the next ibaPADU-
8-ICP device in the ring. Continue until all of up to 96 ibaPADU-8-ICP devices are inter-
connected. Finally, connect the TX port of the final ibaPADU-8-ICP device to the corre-
sponding RX port of the ibaFOB-card.
7.2.3
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 = 32; set S1 = 2, S2=3)
