Operating Manual - nX, nXe, and nXp Power Amplifiers

7 nXp SERIES REAR PANEL FEATURES
*The following nXp features are in addition to all of standard features found in nX and nXe series amplifiers:
7.1 Installed DSP
- Factory installed DSP allows for comprehensive signal processing of amplifier signals
(section
9.4d)
as well as loudspeaker load impedance analysis
(section 9.1i)
.
8 ETHERNET COMMUNICATIONS
(nXe and nXp models only)
Ethernet communication is made by connecting the amplifier directly to a PC running Protea
ne
software or connecting through a network
router, switch, hub, or patch panel using Cat-5, Cat-5e, or Cat-6 wiring. Maximum Ethernet cable distance is 100 meters (328 ft). Ashly nXe
and nXp amplifiers will adapt to either a straight through pin to pin or crossover Ethernet cable.
For wireless iPad control using a custom "Ashly
Remote" user interface, the iPad must be connected to a wireless access point that is connected to the same network (subnet) as the amplifier.
8.1 IP Address
- There is no need to assign an IP address to nXe amplifiers. The router or Link Local Addressing will
assign IP addresses to each device automatically.
When a router is not available, each amplifier will acquire it's own IP address based on Link Local Addressing. This
allows the device to operate without the need to set up static IP address. If the only option is to use an Ethernet switch instead
of a router, and communications problems remain which cannot be solved with the use of the link local standard, each device
can have a static IP address assigned from within Protea
ne
software. This is done by selecting “Manual Configuration” in the
Network Properties tab of each device, where the system/network administrator must assign each product its’ own unique static
IP address, each with the appropriate sub net if applicable.
8.2 Firewalls
- If Protea
ne
software does not detect the amplifier or show real time changes, the firewall in the host PC may
need to have Protea
ne
software added to its firewall exceptions, since firewalls may block the amplifier response to the PC. The current
PC firewall status is found by clicking on the Windows Start button, then Control Panel, then double clicking on the security shield where
firewall exceptions are configured.
8.3 Wi-Fi and LAN
– For the initial device auto-configuration process, any secondary Wi-Fi connection should be
disabled on the PC, and the LAN (Local Area Network) connection must be enabled on the PC. Secondary network connections may
confuse the auto device discovery process. Go to the Windows Control Panel, then Network Connections, to disable any secondary
network connections. Once communications with the device is established, secondary network connections can be enabled again.
8.4 Connecting Device(s)
- Connect the Ethernet cable from the PC or network to the amplifier. If a successful
Ethernet connection has been made, a solid green LED (Link) lights up on the amplifier's RJ-45 Ethernet port. If there is no
green LED showing, there is either a problem with the cable or the network source which must be addressed before proceeding
further. All RJ-45 Ethernet ports flash green when active, so backtrack through any other cables, routers, or switches to find
the problem. The flashing yellow LED (Data) indicates that data is flowing to or from the amplifier.
