User manual YAESU GS-065 APRS MANUAL

[. . . ] The GS-065 has a DB-9 "male" connector for connection to the (RS-232C) COM port of your computer. Purchase or construnct a "straight" type serial cable, ensuring it has the correct gender and number of pins for connection to your system. Firmware on the GS-065 supports either direct keyboard control, or commands from programs written specifically to support it (software is not supplied by Yaesu). In addition to reading and setting antenna angle and rotation speed, the firmware includes clocked positioning routines to auto- matically step the antenna through up to 3800 angles at programmable intervals, such as for tracking band openings or satellites (with an elevation rotator). [. . . ] r Adjust the OUT VOL ADJ potentiometer on Controller rear panel so as to get a reading of "0450" on the computer's display. This reading ("450 degrees") corresponds to the actual beam heading you established when you pointed the azimuth rotator to the East. r Turn off the GS-065's POWER switch to exit the azimuth A-D converter calibration routine, then turn on the GS-065's POWER switch again. Imprtant Note ! If your controller's indicator needle starts from the point except 0° (North) (such as the default setting of the USA version), align the starting point of the controller's indicator needle to 0° (North) before calibration. When finish the calibration, set the controller's indicator needle to the desired point. Refer to the rotator's user manual for details regarding the indicator needle alignment. 8 G-400 AZIMUTH 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 Rotator fully counterclockwise (set to 180°). 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-065) 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-065's POWER switch to exit the azimuth calibration routine, then turn on the GS-065's POWER switch again. Azimuth A-D Calibration r From the Controller panel, set the 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 will return AZaaaa = bbbb, as in the previous procedure, plus ELcccc = dddd to the right, where cccc and dddd are four-digit numbers padded at the left with zeroes. r Adjust the EL trimmer (located on the bottom case of the GS-065), so as to make the numbers cccc and dddd are the same (again, the actual values are unimportant). r Turn off the GS-065's POWER switch to exit the elevation calibration routine, then turn on the GS-065's POWER switch again to turn it back on. Elevation A-D Calibration r From the Controller panel, set the Elevation Rotator to full scal (180°: "right" horizon). 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-065's POWER switch to exit the elevation A-D converter calibration routine, then turn on the GS-065's POWER switch again to turn it back on. CALIBRATION 13 CALIBRATION G-500 ELEVATION 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. The computer will return AZaaaa = bbbb, as in the previous procedure, plus ELcccc = dddd to the right, where cccc and dddd are four-digit numbers padded at the left with zeroes. [. . . ] Start automatic stepping routine (both azimuth and eievation): turn rotator to next sequentially memorized azimuth (or az-el pair, for the [W] command), wait sss seconds, and turn to next angle (or pair), etc. This command works only if a longform [M] or [W] has been issued since power-up or the last reset. Msss aaa bbb ccc This command, together with the [T] command, provides automatic, timed tracking of moving objects or propagation by the Control Interface itself. This command stores the time value sss seconds to wait between stepping from azimuth aaa to bbb, and then to ccc, etc. (from "2" to as many as "3800" angles may be stored with one command). [. . . ]
