Setup9497B-21 C/Ku-Band TVRO5.5. Radiation Hazard and Blockage Mapping (AZ LIMIT parameters)This system may be programmed with relative azimuth and elevation sectors (zones) where blockage exists or wheretransmit power would endanger personnel who are frequently in that area.Refer to your ACU Manual for instructions on programming of these zones.5.6. TX Polarity SetupWith the feed in the center of its polarization adjustment range, observe the transmit port polarity (vector across theshort dimension of the transmit wave-guide).If the transmit polarity in the center of the travel range is vertical, use the following entries:2 Vertical Transmit Polarity4 Horizontal Transmit PolarityIf the Transmit polarity in the center of the travel range is horizontal, use the following entries:2 Horizontal Transmit Polarity4 Vertical Transmit Polarity5.7. TRACK DISPThis parameter set the selections that the user will see in the Tracking - Band Selection menu. Band Selection must beset to the appropriate selection for Tracking to operate properly.Band selection controls the local logic output state of SW1 output terminal on the Terminal Mounting Strip PCB andremote C/Ku relays (or other switches) on the antenna pedestal.The factory default selections and SW1 status for your 9797B is listed in the following table:Setting0000 CXKuLoKuHiDisplayed bandselectionADE Band Select Parameters(Tone, Voltage & Aux Status)Tone OFF, Volt 13, Aux 0Tone OFF, Volt 18, Aux 0Tone OFF, Volt 13, Aux 1Tone OFF, Volt 18, Aux 1TMS SW1StatusOpenShortOpenShortWhen the SW1 output is shorted to ground a current sink of 0.5 amps max is provided to control belowdecks band selection tone generators or coax switches. When SW1 output is open it is a floating output.5-6
