SETTING UP
µScoop can be operated under an ambient temperature of 0° to 45°C
(32°F to 113°F).
Installation in a 19’’ rack
A rack mount tray is available for integrating the units in a rack.
Mount 1 to 3 units in the tray, using the provided screws (do not use
longer screws!). Then set the assembled tray into a 1U space of the
rack.
For a suitable heat dissipation, leave some free space
(10 mm at least) at the top and bottom of the assembled
tray.
Powering
µScoop can be powered in two ways: either by using an external DC
supply, or by connecting to a switch or router capable to provide
power through the Ethernet link (PoE, Power over Ethernet).
In the former case, you can use the provided power adapter
(GST25B12-P1J), or another suitable DC power supply, plugged on
the [10] socket. µScoop runs from a nominal 12 V, but it can run
from a 10 to 16 V voltage, with a maximum consumption of 0.5 A
In the latter case, the Ethernet connection on the PoE switch/router
also provides the unit its power supply. µScoop is detected by a PoE
source as a class 2 powered device.
It is possible to use both power sources at the same time ; µScoop
draws current from the PoE source as a priority, as long as the
voltage of the DC source is less than 13.5 V.
Connection to the IP network
Connect the Ethernet interface (socket [11]) to the network. The
LEDs on the socket show the network presence and possible activity.
For operating the µScoop, first it must be assigned a valid IP address.
Then this address can be used for configuring the device.
Out from the factory, µScoop is set for using a DHCP server. Once
the unit is connected to the network and switched on, there are two
alternatives:
Either a DHCP is indeed present on the network the µScoop is
connected to: in this case the server provides the unit the
parameters it must apply.
Or no DHCP server is available on the network: in this case the
µScoop automatically applies a “link-local” IP address, with a
169.254.x.x pattern. This address can be used to initially access
the µScoop, and then configure it as needed with parameters
more suitable for the network in use.
At this stage, there are several ways to find out the IP address of the
µScoop:
The network administrator can program an address
reservation for the µScoop on the DHCP server;
The network administrator can use a tool for
identifying/detecting the µScoop (for example by consulting
the table of address leases in the DHCP server).
The AetaScan tool can scan you local area network, enumerate
the AETA codecs and display a list with their MAC and IP
addresses. You can download it from the AETA web site
(www.aeta-audio.com, see the µScoop product page).
AetaScan is a Java script Java which runs on every OS.
In every case, the MAC address of the µScoop is useful to identify it; it
is recalled on the sticker [9] on the rear side of the device.
