Determine device IP-Address (Troubleshooting)
If you do not know the IP address of your device, we will show you three ways to determine the address
in this section.
1.
Gratuitous ARP:
denotes a special use of
ARP
. A host sends an
ARP
request broadcast, in which
it enters its own IP address as the source and destination IP address. This procedure is used by
all VIPCOS devices and is output when the devices boot. With a network protocol analyzer such
as Wireshark can be used to determine the IP address.
2.
Keep Alive:
the VIPCOS devices will output this package every 10 seconds. These show the
operational readiness and, if necessary, output error messages. The package includes the IP
address of the device as the source. You can use a network protocol analyzer such as Wireshark
to determine the IP address.
3.
Debug:
The VIPCOS devices have a debug interface which also outputs the device's IP address.
A TTL-USB cable is required to use this interface. Training is required to complete this step.

3.2
Volume adjustment
By setting the IP address and device ID, the basic requirements for communication exist. We would
already be able to establish communication channels between the devices. However, to prevent an
error, we start by adjusting the volume of the device. The settings for loudspeaker and microphone
can be set separately on the device website. If the volume values for loudspeaker and microphone are
set to 0 or a very low value, it can give the impression that the connection has not been established.
We therefore recommend setting a volume of:
Spk. Vol(dB): 55
(max. 63)
Mic. Vol(dB): 45
(max. 72)
Wideband:
active (8 kHz)
