Automatic Configuration; Firmware Update - Electro-Voice PWS-4 Owner's Manual

PROGRAMMABLE WALL STATION
Diagnostic mode is automatically cancelled under following conditions:
• Either no button on the front unit has been pressed for at least 15 seconds
• or the CAN-Bus is operational again
• or unlocking the diagnostic mode has been deactivated in IRIS-Net™.

4.6 Automatic Configuration

If a PWS-C of an existing PWS system needs to be replaced,
• the new device's firmware version has to be the same or newer than the one of the previously installed
unit and
• the settings of the DIP-switches ADDRESS and TERM/BAUD of the old and the new model have to be
identical.
NOTE:
If the to be replaced unit had been used in PROG-Mode with a baud rate unequal 10
kbit/s, the factory default baud rate of the new device needs to be set (see page 13).
If these two conditions are true, the wall station will automatically be configured and put into operation by
the CAN-Bus master.

4.7 Firmware Update

Updating the firmware of a wall panel is done in IRIS-Net™. The current firmware version is included in the
IRIS-Net™ package. If an error occurs during the firmware update procedure (e.g. missing supply voltage),
you can simply start the entire process from the beginning. For detailed information about the update
procedure, please refer to the online help in IRIS-Net™.
