A Page 11 2/2/09 2.5 Menu Settings 2.5.1 Functions This section describes operation of the front panel controls. There are three operator switches, the LCD display and alarm indicator LEDs. All functions for the equipment are controlled by these components. The functions are (see Figure 2.5): Power Up Normal Display Menu 1 Menu 2 Menu 3 Menu 4 Menu 5 Menu 6 Menu 7 Menu 8 Frequency in MHz Gain (0 to +50 dB) Set Unit to Remote Operation (Note: the local controls still function when in REMOTE) Select Non-inverting or Inverting Spectrum Select External 10 MHz Ref (option E) Select 10 MHz Output (option E) Select RS232, RS422, or RS 485 Remote Operation (option Q) Select Remote Address for Unit (RS485 only) (option Q) Save Menu When “R” is selected in any above menu or the next menu item after Menu 8 Alarm indications appear on the LEDs (see figure 2.2). All program changes must start with the operation of the Menu/Execute switch and must also end with the operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed, none of the changes will take effect. If programming is initiated and no operator action takes place for approximately 12 seconds (before the final press of the Menu/Execute switch) the display will revert to its previous status and you will need to start over. 2016-26 Manual, Rev. A Page 12 2/2/09 2.5.2. Power On Settings NOTE: The last status of a unit is retained even when power is removed. When power is restored, the unit will return to it's previous settings. When power is first applied, the LCD display goes through three steps. 1.The LCD goes black to show all segments are functioning. 2.The software version will be displayed. REV 1.00 3.The present frequency and gain of the downconverter is shown. F=2250 G=+00 The unit is now operational and ready for any changes the operator may desire. 2.5.3 Control Switches 1. Menu/Execute - Any change to the programming of the unit must be initiated by pressing the Menu/Execute switch and completed by pressing the Menu/Execute switch. 2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor left or right. 3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions: A. During frequency, gain changes, the vertical movement will raise or lower the selected number in the direction of the arrows. B. For other functions, the vertical switch will alternately turn the function on or off regardless of the direction operated. 2016-26 Manual, Rev. A Page 13 2/2/09 2.5.4 Frequency Changes At any time during the modification process, if you have made a mistake and do not wish to save the changes you have made, do not press the Menu/Execute switch; simply do nothing for approximately 12 seconds, and the system will return to the normal operating mode or scroll to “R” and push the menu/Execute switch and select “NO” in the “SAVE SETTINGS?” window. To change the FREQUENCY: 1. Operate the Menu/Execute switch until you get to the menu item you want to change see Figure 2.5 for the sequence of menu options. The following display is for changing the downconverter frequency: F = 2250 R Pressing the Up/Down switch down will toggle the display to: F = 2350 R By using the horizontal rocker switch the cursor can be moved left or right . F = 2350 R NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE MENU AND INDICATE YOU WANT TO SAVE THE CHANGES. THE CARRIER IS MUTED WHEN FREQUENCY IS CHANGED. When the display indicates the value desired you can push the Menu/Execute switch to the next item: G = +00 R OR you can scroll to “R”, push the Menu/Execute switch to get to: SAVE SETTINGS? Y N Selecting Y will save the new settings. Selecting N will revert to the previous settings. Pushing the Menu/Execute switch then takes you to the default display: F=2350 G=+00 Figure 2.5 shows all the menu items and how to make changes. 2016-26 Manual, Rev. A Page 14 2/2/09 2.5.5 Gain Changes When you get to this menu note that the gain changes will be made as you make them but if you do not wish to save the changes you have made, scroll to “R” and push the menu/Execute switch and select “NO” in the “SAVE SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for approximately 12 seconds, and the system will return to the normal operating mode. To change the GAIN, first push the Menu/Execute switch to get to the gain setting: Operate the Menu/Execute switch until you get to the menu item you want to change (see Figure 2.5 for the sequence of menu options). NOTE: CHANGES TAKE PLACE ON GAIN IMMEDIATELY BUT DO NOT GET SAVED UNTIL YOU GO TO THE SAVE MENU AND INDICATE YOU WANT TO SAVE THE CHANGES. Press the Up/Down switch to change the level in 1 dB steps and then push the Menu/Execute switch to get to the Gain setting: G = +00 R Press the Up/Down switch to change the gain in 1 or 10 dB steps: G = +10 R By using the horizontal rocker switch the cursor can be moved left or right. Pressing the Up/Down switch down will toggle the display digit selected until you have the desired gain. NOTE: THE GAIN WILL BE CHANGED AS YOU ADJUST THE NUMBERS. HOWEVER, THE VALUE WILL NOT BE STORED UNTIL YOU INDICATE YES IN THE SAVE SETTINGS WINDOW. DO NOT SET A GAIN THAT WOULD EXCEED 0 dBm OR HAVE LESS THAN -20 dBm OUTPUT LEVEL. THE FIRMWARE PREVENTS YOU FROM THIS. When the display indicates the value desired you can push the Menu/Execute switch to the next item OR you can scroll to “R”, push the Menu/Execute switch to get to: SAVE SETTINGS? Y N Selecting Y will save the new settings. Selecting N will revert to the previous settings. Pushing the Menu/Execute switch then takes you to: F=2350 G=+10 Figure 2.5 gives the menu items and how to make changes 2016-26 Manual, Rev.

A Page 16 2/2/09 2.6 Use Information A. Elevated operating ambient temperature - if installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack may be greater than room ambient temperature. Therefore, consideration should be given to Tmra. B. Reduced air flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Additional space between unit may be required. C. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition does not exist due to uneven weight distribution. D. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits could have on over current protection and supply wiring. Appropriate consideration of equipment name plate rating should be used, when addressing this concern. E. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connection to the Branch (use of power strips). F. Top Cover - There are no servicable parts inside the product so, the Top Cover should not be removed. If the Top Cover is removed the ground strap and associated screw MUST BE RE-INSTALLED prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS emission problems. 2016-26 Manual, Rev.
