Introduction and Installation 1 Affinity Control User’s Guide Software v2.50 1 Introduction and Installation 1.1 Program Description The Affinity Control software is designed to allow for minor adjustments to the Affinity system Upconverter/Amplifier plug-in module (hereafter referred to as "upconverter"). Control and monitoring for normal day-to-day operation is provided on a main control screen. Calibration, adjustment, and setup functions are provided through additional maintenance screens.
Introduction and Installation 2 Affinity Control User’s Guide Software v2.50 1.4 Initial Setup Connect the DB9 connector of the serial interface cable to an unused PC serial port connector. Connect the other end of the cable to the upconverter RJ11 serial port connector (see Figure 1). Figure 1 Upconverter RJ11 Serial Port Connector To start the program, click on the program Icon. The first time that the program is started a popup window will appear (see Figure 2) requesting that the setup be run.
Program Operation 3 Affinity Control User’s Guide Software v2.50 2 Program Operation 2.1 Main Control Screen Operation The Main Control screen is the primary interface to the upconverter module. It displays the current operating power levels and status. It also includes controls for adjusting system output power, upconverter ON or OFF (Transmit or Standby), upconverter reset, and access to the fault history log file.
Program Operation 4 Affinity Control User’s Guide Software v2.50 2.1.1 Upconverter LCD Metering and Status Box The power readings shown are basically a duplicate of the LCD display readings on the upconverter itself. However, the values displayed by the program are averaged for increased stability. • Forward Pwr – Displays the current system output forward power (averaged 3 samples). • Reflected Pwr – Displays the current system reflected power (averaged 3 samples).
Program Operation 5 Affinity Control User’s Guide Software v2.50 2.1.3 Fault Log Screen Operation Clicking on the Fault Log button in the Main Control Screen will open the Fault History Logfile display (Figure 6). Clicking the Next Page button will display the next page of the file. Clicking the Prev Page button will display the previous page of the file. The contents being displayed can be copied and pasted into another program if desired, but the information cannot be edited.
Program Operation 6 Affinity Control User’s Guide Software v2.50 2.1.4 Maintenance Options Screen Operation Most of the buttons in the Maintenance Options Screen (Figure 7) will open additional windows. The following buttons are described below: • Setup/Config – Clicking this button will open the Setup/Configuration dialog window. Refer to the Setup/Configuration Screen Operation section of this document for details.
Program Operation 7 Affinity Control User’s Guide Software v2.50 2.1.5 Setup/Configuration Screen Operation The Setup/Configuration Screen (Figure 8) allows various program parameters to be adjusted, saved, and applied. A Setup Help screen located on the right side of the dialog describes most of the controls and their functions. More detail on each control is provided here: 2.1.5.
Program Operation 8 Affinity Control User’s Guide Software v2.50 2.1.5.2 Power Alarm Trip Settings These controls are used to set upper and lower alarm points for the forward and upconverter power meter readings. These limits do NOT cause the program to take any action other than to log the fault and display it on the Main Screen. If either the forward or upconverter power levels are outside the limits, the corresponding Power display box on the Main Screen will be highlighted red.
Program Operation 9 Affinity Control User’s Guide Software v2.50 • Fast Reflected Shutdown Trip – Use the Up/Down control to adjust the trip point for the Fast Reflected Shutdown. The only possible reason that this may require adjustment is to eliminate nuisance trips occurring when the ADAPT output is turned on. Adjust the level up by one click, reset the upconverter, and turn the ADAPT drive output control OFF and ON. If trip reoccurs, repeat this process until the upconverter no longer trips.

Program Operation 14 Affinity Control User’s Guide Software v2.50 Figure 16 Amplifier Gain Check for 500W System (Screen 6) Figure 17 Amplifier Gain Check for 500W System (Screen 7) The block representing the amplifier being tested is highlighted yellow when it should be turned OFF, highlighted white when it is to be turned ON, and highlighted blue when the test is completed.
Program Operation 15 Affinity Control User’s Guide Software v2.50 amplifier OFF is displayed below the amp. Note that the program does NOT actually know which amplifier is being turned OFF and assumes that the operator is following the sequence as highlighted. If the sequence is not followed correctly, the values under each amplifier block will not be correct for the specific location shown.
Program Operation 16 Affinity Control User’s Guide Software v2.50 • Adjust the Fast Refl Shutdown Threshold value to set the reflected power –6dB trip level to 15% system reflected power. • Adjust the Fast Refl Power Percent Limit to set the reflected power shutdown trip level. Every calibration screen contains a help window on the right side. The instructions for each step are shown in this window. The left side of the screen shows each of the variables to be set during the calibration.
Program Operation 17 Affinity Control User’s Guide Software v2.50 The screen shown in Figure 19 displays a "last chance" warning message. Clicking on the Next button in this screen will erase any previous parameters stored in the upconverter and initialize it using default values. Clicking on the Cancel button will terminate the procedure without any changes being made to the upconverter settings.
Program Operation Affinity Control User’s Guide Software v2.50 The screen in Figure 21 instructs the operator to adjust the output level of the ADAPT for +6dBm to +7dBm. This is the OPTIMAL input level for the upconverter. Although it will operate at lower (and higher) input levels, the best performance can be achieved with this level. Figure 21 Full Calibration-ADAPT Output Level The screen in Figure 22 is informational only.
Program Operation 19 Affinity Control User’s Guide Software v2.50 The screen in Figure 23 performs the calibration of the ALC Manual Ref parameter. This parameter controls the output level of the system when in ALC Manual mode. Figure 23 Full Calibration-ALC Manual Ref Calibration The screen in Figure 24 instructs the operator to connect a forward power sample to the upconverter forward power sample input.
Program Operation 20 Affinity Control User’s Guide Software v2.50 In Figure 25, adjustment of the System Fwd Pwr Ref is performed. This calibrates the upconverter LCD display reading for "System Forward Pwr." Figure 25 Full Calibration-System Fwd Pwr Ref Calibration The screen in Figure 26 is informational only.
Program Operation 21 Affinity Control User’s Guide Software v2.50 In Figure 27, the Upconv Fwd Power Ref parameter is calibrated. This calibrates the Upconverter LCD "Upconv Forward Pwr" reading. Figure 27 Full Calibration-Upconv Fwd Pwr Ref Calibration The screen in Figure 28 instructs the operator to connect the samples used for the Fwd Pwr Ref calibration, to the upconverter Reflected Pwr sample input.
Program Operation 22 Affinity Control User’s Guide Software v2.50 In Figure 29, the System Refl Power Ref is calibrated. This calibrates the Upconverter LCD "System Refl Pwr" reading. Figure 29 Full Calibration-System Refl Power Ref Calibration This screen is informational only.
Program Operation 23 Affinity Control User’s Guide Software v2.50 The screen in Figure 31 is also informational only and simply describes what will be done in the next step of the procedure. Figure 31 Full Calibration-ALC Auto Ref Info In this step, the upconverter is placed into ALC Auto mode prior to adjustment of the ALC Auto Ref parameter.
Program Operation 24 Affinity Control User’s Guide Software v2.50 The adjustment and calibration of the ALC Auto Ref parameter is performed in this step. This calibration parameter controls the system output power during normal operation. Figure 33 Full Calibration-ALC Auto Ref Calibration Figure 34 is an informational only screen describing the next step to be performed.
Program Operation 25 Affinity Control User’s Guide Software v2.50 In this step, the ALC Auto Ref value is increased to approximately 130% to set the Power Limiter threshold value. The maximum power limit can be set as desired; a threshold of 130% is provided as an example. Figure 35 Full Calibration-Power Limiter Setup This step performs the actual adjustment of the Power Limiter parameter. The power limiter is set to limit the maximum system output to the level desired.
Program Operation 26 Affinity Control User’s Guide Software v2.50 In this step, the program restores the previously calibrated ALC Auto Ref value to return the system to its normal full power level. Figure 37 Full Calibration-ALC Auto Full Power Restore This is an informational only screen that instructs the operator in the setup required to calibrate the Fast Reflected Shutdown Threshold value. Setting the required reflected power sample levels is best accomplished with a variable attenuator.
Program Operation 27 Affinity Control User’s Guide Software v2.50 In this step, the Fast Reflected Shutdown Threshold parameter is adjusted until the system detects the 15% reverse power threshold. This will cause the system to reduce power by approximately 6dB. It may require several tries to get the threshold set accurately (within 20 units of true threshold). As described in the instructions, increase the Fast Reflected Shutdown Threshold slightly and use the Reset button to clear the trip fault.
Program Operation 28 Affinity Control User’s Guide Software v2.50 This step will perform the adjustment on the Fast Reflected Power Percent Limit value in order to set the trip point for full system power shutdown. Normally, this is accomplished automatically. However, in some cases the value may need to be decreased by one or two percent.
