======Connecting the 52/XS2 or 52/XC2 Core======

The 52/XC2 and 52/XS2 cores offer a variety of ports. See below how the cores have to be connected.

[{{ :sx2:7424_rear.png?600 |//Rear view of 52-7424//}}]
[{{ :sx2:1830_rear.png?600 |//Rear view of 52-1830//}}]

===== Network Connection =====

To send the configuration to the 52/XC2 and 52/XS2 cores, see the system state and also for sending and receiving external control data, both devices have one ethernet interface ''ETH1''. Connect the ''ETH1'' connector to a network matching the [[network:start|DHD Network Specifications]].

<WRAP center round important 80%>
**Important**\\  Never connect the ''ETH1'' port of a DHD Series 52 core device to a unrestricted network. This would be a major security issue.
</WRAP>

<WRAP center round important 80%>
**Important**\\  Only the ''ETH1'' port is an ethernet port. APC-Ports are no ethernet ports. Connecting APC ports to a non-DHD-device or a network switch can cause serious damage!
</WRAP>

On the same network connector, also an internal Dante Ultimo 4x4 Audio over IP interface is running. Thus this is only one physical connector, the Dante™ Ultimo ''Dante 4x4'' and ''ETH1'' port are different devices running on different interfaces. They have to be configured seperately and also have a different set of network options and IP/MAC address. The Dante 4x4 Interface is configured using Dante™ Controller. For more information on configuration of Dante devices, see [[dante:start|Dante™ information]].

===== Connecting modules to the APC ports =====

The control modules and I/O boxes have to be connected to the APC ports of the 52/XS Cores 52-18xx. It is important to connect the peripheral modules to the correct APC port. 

<WRAP center round important 80%>
**Important**\\  Use always shielded CAT5 or CAT6 ethernet cables (at least S/UTP, F/UTP or SF/UTP) to connect these modules to the XS core.
</WRAP>
<WRAP center round important 80%>
**Important**\\  See [[installation:apc|APC documentation]] for more information on APC.

In the following table you can find the assignment of the control modules, I/O boxes, DeviceLinks and TFT/Touch displays to the APC ports. 

^Name of the APC port^52-7424^52-1830^
|APC 1|Central control module (52-5614)|Central control module (52-5614)|
|APC 2|Fader module 1 (52-5620)|Fader module 1 (52-5620) / I/O box 3 / Device Link ((On 52-1830 core device, APC-Ports 2 and 3 can be used for both I/O boxes, device Link or Fader Modules, depending on the amount of fader modules you have in your bundle.))|
|APC 3|Fader module 2 (52-5620) / I/O box 6 / DeviceLink ((On 52-7424 core device, APC-Port 3 can be used for both I/O boxes, device Link or Fader Modules, depending on the amount of fader modules you have in your bundle.))|Fader module 2 (52-5620) / I/O box 2 / Device Link ((On 52-1830 core device, APC-Ports 2 and 3 can be used for both I/O boxes, device Link or Fader Modules, depending on the amount of fader modules you have in your bundle.))|

===== Connecting 52-7321 MADI modules =====

The 52-7321 MADI module supports up to 64 channels. It is always configured to ''SFP 1'' housing. See [[installation:fibre|Fibre optical connections documentation]] on wiring.

===== Connecting 52-7391 Gigabit Audio (GA) modules =====

The 52-7391 Gigabit Audio (GA) module supports up to 512 channels. Gigabit Audio is a DHD proprietary audio connection protocol and only works between DHD devices. It is always configured to ''SFP 2'' housing. See [[installation:fibre|Fibre optical connections documentation]] on wiring.

===== Connecting 52-7080 Dante Brooklyn modules =====

The 52-7080 Dante Brooklyn Audio over IP module is connected to the internal Core extension slot (upper right corner of the back of the core). It always contains a ''Primary'' (left) and a ''Secondary'' (right) ethernet port. You can connect it to any network. See [[dante:start|Dante™ information]].

===== Connecting 52-7067 AES67 RAVENNA modules =====

The 52-7067 AES67 RAVENNA Audio over IP module is connected to the internal Core extension slot (upper right corner of the back of the core). It always contains a ''Primary'' (left) and a ''Secondary'' (right) ethernet port. You can connect it to any network. See [[aes67:start|AES67 RAVENNA Interface documentation]].
