The GS-232A contains its own microprocessor with ROM and RAM (memory), and a l0-bit analog-to-digital (A-D) converter. The 3-wire async serial line can be configured for serial data rates from 150 to 9600 baud. [. . . ] The computer's display should show +aaaa, where aaaa is a four-digit number which indicates the azimuth heading in degrees. r Adjust the FULL SCALE ADJ on the GX-500 so as to get a reading of "0180" on the computer's display. This reading ("180 degrees") corresponds to the actual beam heading you established when you pointed the azimuth rotator to the South (the fully clockwise setting). r Turn off the GS-232A's POWER switch to exit the azimuth A-D converter calibration routine, then turn on the GS-232A's POWER switch again to turn it back on. CALIBRATION 9 CALIBRATION G-5400B/-5600B AZ-EL ROTATOR Azimuth Offset Null r Before calibrating the Rotator, check to see that the GS232A's DIP switch (switch 5) is set to the "OFF" position. r From the Controller panel, set the Azimuth Rotator fully counter-clockwise (set to 180°). r Press [F2] Z [] (F, 2, and ENTER) on the computer keyboard to activate the Control Interface's elevation A-D converter calibration routine. The computer will display +aaaa+eeee, where eeee is a four-digit number which indicates the elevation heading in degrees. For the purposes of this alignment, you may ignore the (azimuth) aaaa numbers. r Adjust the OUT VOL ADJ potentiometer on the "ELEVATION" (right) side of the Controller rear panel so as to get a reading of "0180" on the computer's display. This reading ("180 degrees") corresponds to the actual beam heading you established when you pointed the elevation rotator to the 180° position. r Turn off the GS-232A's POWER switch to exit the elevation A-D converter calibration routine, then turn on the GS-232A's POWER switch again to turn it back on. CALIBRATION 11 CALIBRATION G-5500 AZ-EL ROTATOR Azimuth Offset Null r Before calibrating the Rotator, check to see that the GS232A's DIP switch (switch 5) is set to the "ON" position. r From the Controller panel, set the Rotator fully counterclockwise (set to 0°). r Press [O] Z [] (the letter "oh", and "ENTER") on the computer keyboard to activate the azimuth calibration routine. The computer display should show AZaaaa = bbbb returned from the Interface Board, where aaaa and bbbb are four-digit numbers padded at the left with zeroes. r Adjust the AZ trimmer (located on the bottom case of the GS-232A) while watching the computer display, until the four-digit numbers aaaa and bbbb are the same (the precise values are not important). r Turn off the GS-232A's POWER switch to exit the azimuth calibration routine, then turn on the GS-232A's POWER switch again. Azimuth A-D Calibration r From the Controller panel, set the Azimuth Rotator fully clockwise (to the right). r Press [F] Z [] (F and ENTER) on the computer keyboard to activate the Control Interface's azimuth A-D converter calibration routine. The computer's display should show +aaaa, where aaaa is a four-digit number which indicates the azimuth heading in degrees. r Adjust the OUT VOL ADJ potentiometer on the "AZIMUTH" (left) side of the Controller rear panel so as to get a reading of "0450" on the computer's display. This reading ("0450: 360 degrees + 90 degrees") corresponds to the actual beam heading you established when you pointed the azimuth rotator fully clockwise. r Turn off the GS-232A's POWER switch to exit the azimuth A-D converter calibration routine, then turn on the GS-232A's POWER switch again. 12 G-5500 AZ-EL ROTATOR Elevation Offset Null r From the Controller panel, set the Elevation Rotator to the "left" horizon (down, set to 0°). r Press [O2] Z [] (the letter "oh, " "2, " and "ENTER") on the computer keyboard to activate the elevation calibration routine. [. . . ] Note that this command is completely different than the [T] command with only one parameter: when multiple parameters are present, the first one is interpreted by the Control Interface as the rotation interval sss, not an angle. Valid ranges are "001" to "999" for sss, and "000" to "360 or 450: vary according to controller type" for the angles. When this command is sent, the parameters are stored in the Control Interface's RAM, and the rotator turns to angle aaa and waits for a subsequent [T] command to begin the actual stepping. All numbers must be 3 digits, space-separated. [. . . ]
