======Connecting modules to the XS Core======
The control module and I/O boxes have to be connected to the APC ports of the 52/XS Core 52-1804. It is important to connect the peripheral modules to the correct APC port.
**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.
In the following table you can find the assignment of the control module, I/O boxes and DeviceLinks to the APC ports.
|**Name of the APC port**|**52-1804**|
|APC 1|52-1114 (52-1104) 52/DX control module|
|APC 2|I/O box 3 / DeviceLink 3|
|APC 3|I/O box 2 / DeviceLink 2|
|APC 4|I/O box 1 / DeviceLink 1|
===== Example 4 Fader 52/DX and 1 Multi I/O box =====
**Important**\\ Use minimum **Firmware version 07-04-19** and **DXConfig version 7-4-8-0** or the version on the CD supplied with the console, which may be a later version.
