Connection of Multiple Units on an RS485 Network
The USB Connection is the easiest and quickest way to connect to a single unit when uploading presets or updating firmware, and is the best connection for a "set and forget" system, where the cable can be unplugged and the system then left secure. If, however, a larger system of more than one unit is required, and real time monitoring and adjustment of these units is required on a regular basis, then the RS485 network connection on the rear panel is more useful. Additionally, other devices can share this RS485 network and can be monitored and controlled through ICORE.

Connection directly to the RS485 Network
If a connection to the first unit cannot be easily achieved with a USB cable (due to location of this unit) then a longer RS485 connection is possible via the rear panel connection using a suitable RS485 converter. We recommend the KK Systems USB-485 adapter for simple conversion to RS485.
This device is powered via the USB connection and so has the ability to drive long cable runs reliably. This device is available from us, or directly from KK Systems at www. kk-systems. com. The converter comes with a 9-pin D-type fitted as standard this has to be adapted to an XLR connection. To prevent voiding the warranty on the converter, we advise not cutting the 9-pin off, but rather make up an adapter the pin out for this is below. 9-pin D type Pin 4 Pins 3+7

Remember to set the first unit to SLAVE mode instead of MASTER so it accepts data on the rear Phoenix instead of the USB. Also, the baud rate setting in iCore now must match that of all connected units. See page 14 for how to change this.

Connect to the first unit via its RS485 socket. To connect to further units, just use standard microphone cable (or similar), come out of the first unit on the Phoenix and simply parallel the three wires to the next device, and so on down the chain as shown in the previous diagram.
Laptop or desktop PC running iCORE software monitors and controls all units.

We strongly recommend that you use screened cable for these connections and be sure to ground one end of the screen. As the RS485 drivers used are "quarter load" devices, the maximum number of nodes that can be connected together is 128, and the maximum theoretical cable length from the first node to the last node is 1000 metres. This distance will be affected by the cable quality and to some extent the operating environment.

Security and Locking
Overview
The DC1048 and ICORE both have security systems that allow for local and remote security to be implemented entirely independently. Via the front panel of the unit itself, control may be restricted or entirely prevented. Through ICORE, access to internal unit settings may be restricted though user levels with individual rights given to up to ten users, each with their own username and password.
Local Front Panel Locking
Pressing the Sys. [. . . ] However, the gain does increase again above this frequency to settle at 12dB down from 0dBr. This filter can be used in conjunction with the standard crossover filters to produce sharper roll-offs than would be otherwise achievable. As can be seen, number 2 is significantly steeper in roll-off than number 1, as would be expected. 1 2

However, number 3 is a 12dB/Octave Butterworth filter with an Elliptical Low Pass filter following it. [. . . ]
