System integration
As far as no special relation to a PC board is necessary the ibaFOB-S-, -D- or -Dexp-
cards are referred to as ibaFOB card.
ibaPADU-8-ICP devices are interconnected in a ring structure with the ibaFOB serving
as a central controller for all connected devices. Each link on the ibaFOB card has a
TX/RX port for transmission of control signals and reception of data from connected
ibaPADU-8-ICP devices. All devices connected in each fiber-optic link must have
unique addresses.
Figure 1. Ring topology
The TX port on an individual iba-
FOB interface must be con-
nected to the RX port on the first
ibaPADU-8-ICP in the fiber-optic
ring. Installed devices may be in-
terconnected in any order (con-
secutive addresses are not re-
quired) provided that all devices
have unique address settings
(0…95). The TX port on the last
device in the chain must be con-
nected to the RX port on the re-
spective ibaFOB interface card.
Important note
This ring topology is only supported by ibaLogic-V3, since numbering of the devices
can be done automatically in ibaLogic-V3.
The ring topology can also be used in ibaPDA or ibaScope, but the automatic number-
ing is not possible. The user has to change the device number and to restart the acqui-
sition. Therefore this topology is not advisable for continuous measuring.
