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). [. . . ] 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'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 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. 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 scale (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. [. . . ] Remember that elevation commands require the G-5400B, G-5600B or G5500 AZ/EL Rotators, or the GX-500 adapter and the G500 or G-550 Elevation Rotator. R (U ) Start turning the rotator to the right (up) L (D ) Start turning the rotator to the left (down). A (E ) Stop azimuth (elevation) rotation. 0 (02) Offset calibration for internal AZ (EL) trimmer potentiometer: preset rotator manually fully counter-clockwise, send command, and adjust trimmer on Control Interface until returned values are equal. Turn off the GS-065's POWER switch to store settings. S Stop: cancel current command before completion. C (B ) Return current azimuth (elevation) angle in the form "+0nnn" degrees. H (H2) Returns list of commands (see page 19). C2 Return azimuth and elevation ("+0aaa+0eee", where aaa = azimuth, eee = elevation). F (F2) Full Scale Calibration: preset rotator manually to full scale, send command, adjust OUT VOL ADJ trimmer on rear of controller (or GX-500 elevation adapter) until the returned data is "+0180 or +0450" ("+0nnn+0180" for elevation). Turn off the GS-065's POWER switch to save new settings. Xn Select azimuth rotator turning speed, where n = l (slowest) to 4 (fastest). This command can be issued during rotation, and takes effect immediately. [. . . ]
