Controller modules for the 52/RX.
Since the revision RM420-852B/853B, the upper RJ45 connector provides an RS422 interface (not useable as RS232). On
previous modules this port has no function.
The middle connector of the three jacks is the interface to the controller network. Connect your console(s) to this RJ45
jack. Therefore, connect this port to a PoE switch, as well as all the fader and control modules and TFT displays. All
modules of this network own an unique IP address, which should not be changed. In the system drawing above the
required PoE switch is installed in a power frame. It is also possible to mount the PoE switch next to the console and to
use a separate power supply.
For configuration and controlling processes, as well as communication with other DHD Systems, the device can be
connected to a PC or a local network via the lower RJ45 connector. The DHD system can get any IP address in this
network.
Use the USB port of the communication controller module if you want to connect directly to the device for maintenance.
General Information
Please use CAT5 cables continuous for wiring. But DHD recommends to use CAT6 cables for longer distances. The
maximum length of the Ethernet cable between two modules of the Controller network is 100 meters (for instance
between the Communication Controller of the DSP frame and a PoE switch or between a PoE switch and 52-4050
Controllers - that are included in the 52/XR fader and control modules. Use only switches in the DHD network and the
controller network, which are shipped and/or recommended by DHD for the usage in these networks. Especially the
switches must be Unmanaged Switches working with a speed of 100 Mbit/s.
The following switches are tested by DHD and are recommended for the usage in DHD Ethernet networks:
