P 64 Digital Audio Matrix
Owner’s manual
SYSTEM STATUS-LEDs
These LEDs indicate device or system states. The READY-
LED is on when the device has booted after switch-on and
when it is ready for operation. An illuminated FAULT-LED
indicates an internal error in the P 64. During the
configuration of the P 64, it can be specified which errors
should be displayed. If the FAULT display is on, the error should be identified promptly. This can
be done using the detailed diagnostics within the IRIS-Net PC software. The source of the fault
has to be remedied immediately.
POWER-LED
This LED is permanently green when the P 64 is powered
on. If the ON indication is not illuminated, even though the
device is switched on, this device may not be connected to
the power supply system or the primary fuse may be faulty.
USB Interface
A PC can be connected at the front panel via the USB
interface. Thus, it is possible to connect the P 64 with a PC
even it is already installed - i.e. when the Ethernet interface
at the rear panel is perhaps no longer accessible. Via the
USB interface the network parameters of the P 64 can be
edited and files containing the entire P 64 configuration can
be transferred. You can find the necessary USB driver in the subdirectory \Driver\USB Netmax
Driver in the IRIS-Net setup directory. Please see chapter Interface description for more
information on technical details concerning the USB interface and the other interfaces of the P 64
which are described in the following section.
