Page 9 of 33b) RS232 Interface. Table 2-2 shows signals and pin out of the RS232 connector on the rear panel of theamplifier. Details about connecting and using the RS232 interface are given in the Technical compactdisk (CD) – option to the amplifier and / or in the respective control programs.This connector can remain unconnected until you decide to use the amplifier with remote control.Table 2-2RS 232interfacePINNO.PINNAMEDESCRIPTION SPECIFICATIONSRear panelview1 - Not connected -2 TxD Transmitted Data RS232 level output3 RxD Received Data RS232 level input4 - Not connected -5 GND Ground 0 Volt6 DSR Data Set Ready RS232 level input7 - Not connected -8 CTS Clear To Send RS232 level input9 - Not connected -3. INITIAL POWER ON AND SETTING INTO OPERATIONC A U T I O NDo not turn on the amplifier for at least two hours after it is unpacked andinstalled in its operating position. Pay particular attention whenever theamplifier is moved from a very cold place to a very warm one becauseunseen condensation may develop and this could result in damage to thehigh voltage circuits of the amplifier. Under these circumstanves, do notturn on the amplifier for at least 4 hours. A similar effect could occurfollowing a rapid warming of the room, such as winter use of a powerfulelectric heater.After having mounted and connected the amplifier according to the instructions in Section 2 INSTALLATION andhave followed all requirements, check whether mains switch on the rear panel is in turned-off position – in Fig. 2-1 the rocker of the POWER ON switch must be protruding from the side of the “ON” inscription. Afterwards insertthe mains plug of the amplifier into the mains outlet prepared for it. For now the amplifier remains turned off.3-1. Low-energy (waiting) mode of the power supplyNow you can put the mains switch on the rear panel in a turned-on position, pushing its rocker so that it sinksfrom the side of the “ON” inscription (Fig. 2-1). This will activate only the low-energy (waiting) mode of the powersupply and will illuminate the red LED above button ON/OFF on the front panel, while the main power supply isstill inactive and the display is dark.3-2. Front panel - controls and indicationa) ON/OFF button – serves for manual (local) start up of the power supply from low-energy (waiting) modeof the power supply (S. 3-1) into working mode, i.e. for activating of the main power supply and startingoperation with the amplifier. The same button is used also for main power supply deactivation – returninto the low-energy (waiting) mode of the power supply at ceasing operation with amplifier.b) LED indicator above the ON/FF button. The red LED indicator glowing above the ON/OFF button at adark display shows that mains voltage is fed from the plug, the POWER ON switch on the rear panel(Fig 2-1) is in a turned-on position, but the power supply is in its low-energy (waiting) mode (S. 3-1). Inthis mode activation of the main power supply is expected to start operation with the amplifier.
