read thirty. Set the west limit by pressing the “W” key and verifying that the AZ count value is
increasing. Then press 7 to set the west limit. Hit the BKSPC key to confirm the limits setting.
16. Set the down limit by pressing the “S” key and verifying that the EL count value is decreasing.
Then press 9 to set the down limit. The EL count should now read 30. Set the up limit by pressing
the “N” key and verifying that the EL count value is increasing. Then press 9 to set the UP limit. Hit
the BKSPC key to confirm the limits setting.
17. If the controller is the “B” or “C” version go to CONFIG mode and scroll to “ENTER DATE” to set
the date and time.
18. Return to config mode and scroll to REMOTE MODE ENABLE. Set it to 1. (this is not available on
the RC2000B) Scroll to AUTOPOL ENABLE and set it to 1.
19. Toggle the mode key to reach SETUP mode. Test the speed control algorithm by pressing the
“Speed” key for a “SLOW” speed display and pressing the “E” key for mount movement. The
speed servo should display status beginning with around 12 on the display ramping up to about 24.
This should accompany a motor speed increase. Repeat this for “S” motion.
20. Select any Satellite from the scrolling list other than the “USER” entry. For “B” and “C” versions
select “NO” for inclined orbit operation. Enter 0.0 for the satellite longitude. Hit enter for east
longitude and select 2, “USER ENTRY” for the polarization data.
21. Press CW and note the movement of the test polarotor. Press H to set. Press CCW and note the
opposite movement of the test polarotor. Press V to set. The RC2000 should now display “DATA
ACCEPTED”.
22. Cycle the power on the RC2000 off, then on. The software should come up in manual mode.
23. Test the autopol function by shorting the probe attached to the H/V input (pin 8 connector J1) to
ground. This action should skew the test polarotor between the two previously stored polarization
positions.
24. The following remote mode test is only valid for “A” and “C” versions. Attach the test
communications cable to the comm. port, J3. Run the program RC2K.EXE on the test computer.
Select the baud rate D, 9600. Select the comm. port in use. Enter “C” and type in the device
address of “50”. Type the letter “E” on the computer keyboard. The PC screen should contain data
in both the top (transmit half) and bottom (receive half) of the screen. “REMOTE” should appear in
the upper right hand corner of the RC2000 display.
25. The following feed drive test is valid only for “A” and “C” versions that contain the optional rotating
feed drive, option RC2KPOL. Install and connect the optional feeddrive. Adjust pot P1 so that the
voltage on the reference pin (pin 3) of the feeddrive is 5.0V. Turn on the RC2000 and attach the
rotating feed test plug to the feeddrive under test. Turn on the unit; go to CONFIG mode and scroll
to the item, POLAROTOR PRESENT. Set this item to 0. Scroll to Autopol enable and set this
item to 0. Go to manual mode, press “CW” and “CCW” to verify rotation of the test feed.
26. Go to CONFIG mode, scroll to RESET SYSTEM DATA, and type in the code 41758. Test
Completed.
