Special functions
Change the ID number of the amplier
When controlling the amplier by the external protocol on either RS-232 or LAN, the unit re-
sponds to commands that are sent to it according to its assigned unit ID number. By default the
amplier has unit ID 1. The ID number can be changed by RS-232, LAN or the front panel buttons.
To change the unit ID by RS-232 or LAN see the protocol on page 21.
To change the unit ID with the front panel buttons:
• Connect power to the amplier. If currently connected, disconnect and then reconnect.
• Within ve seconds of power connection, press and hold the source button until one of the
source LEDs starts blinking. The blinking light LED corresponds to the current unit ID number.
• Toggle through the source LEDs by pressing the source button, selecting any “source”
from 1 to 5. The source number corresponds to the new unit ID number.
• Press and hold the source button for 5 seconds to store the selection as the new unit ID.
When the amplier is powering up, it indicates its current unit ID on the source status
LEDs by illuminating the source LED with same source number as the unit ID.
Reset to factory default
To reset all amplier settings to factory default settings either use the FACTORYDEFAULT com-
mand as described in section “System functions” on page 22 or follow the below procedure:
• Power up the amplier.
• Then press and hold all three front panel buttons for 5 seconds.
• The amplier will now reboot and have all settings restored to factory default.
Upgrade the rmware
Use the Neets Project Designer program to update the rmware by following this procedure.
• Start Neets Project Designer on your PC.
• Connect the amplier USB cong port on the front to a PC USB port.
• If a new rmware is available for the amplier a dialog box will appear in the Project
Designer with a guide for the rmware update process.
