Find Function; Diagnostic Mode - Electro-Voice PWS-4 Owner's Manual

4.4 Find Function

The Find Function simplifies identifying a programmable wall station when a variety of (identical) wall
stations are operated on the same CAN-Bus. When the Find Function is active, the CAN-STATUS-LED on
the PWS-C's rear blinks (and, if existing, the LEDs of the front unit selected in IRIS-Net™) as shown in the
table on page 15. The LEDs of all other wall stations for which the Find Function has not been activated do
not light. Notes on how to use the Find Function can be found in the IRIS-Net™ documentation.

4.5 Diagnostic Mode

The diagnostic mode allows the convenient querying the hardware configuration of a PWS wall panel,
including CAN-Bus address, baud rate, etc., without dismounting the wall panel. In diagnostic mode the
front unit that is directly connected to the CAN-Bus coupler is being queried.

Table 4.5: Parameters of the bus coupler that can be queried in diagnostic mode
Manually accessing diagnostic mode is possible under following conditions:
• Either the CAN-Bus is out of operation (e.g. when CAN-address 0 has been set)
• or activation for the wall panel's diagnostic mode has been unlocked in IRIS-Net™ (refer to the online
help in IRIS-Net™).
If one of these conditions is true, please proceed as follows to access diagnostic mode:
1. Press any button on the programmable wall station and hold it down for at least 5 seconds.
Three times flashing all of the LEDs on the front panel of the PWS indicates that diagnostic mode has
been activated. Following that, the 4 upper LEDs light, as explained in line "1" of table 4.5
2. The 4 upper buttons of this front unit can be used to query the desired parameters.
Parameters that can be queried in diagnostic mode are listed in table 4.5.
Indicated Parameter
