Note
Firmware may only be updated by iba!
A 9-pin SUB-D port, found on the under side of the device, may be used to load new
firmware for the device. New firmware is loaded via a V.24 interface. Please contact iba
regarding loading new firmware.
The firmware will be loaded via the pins 2, 3, 5 and the bootpin (7). At first, the device
must be set into boot mode by applying 0 V to the bootpin and then the device must be
booted (switch off and on the power supply). Now the device is in boot mode and ac-
cepts the new firmware. Afterwards the V.24 cable has to be removed (or apply 5 V to
the bootpin) and the device has to be rebooted. The device is now booting with the new
firmware.
Under normal service conditions, the V.24 cable must not be connected.

Shield Connector for Physical Earth
Proper connection of cable shielding to the device should be ensured. The shield con-
nector found on the underside of the device should be connected with any total shield
that serves for all sensor cables. In addition, each individual sensor channel shield
must be connected to its respective input channel shield pin.
Note
Sensor cable shield should be connected only on the ibaPADU-8-ICP side in order to
avoid ground loops with the sensor housing.
Note
Always ground the DIN rail on which the device is installed.
