Setup the system

1. Connect the power cable to the GTO control box. Since the motor cables are not needed for the download, you can use just the GTO control box, you don’t have to use the whole mount. DO NOT connect the keypad at this time. DO NOT turn the power on yet.



2. Connect the RS-232 cable to your personal computer and the GTO control box. This upload process will only work if you plug the cable into the TOP RS-232 connector (marked COM 1 on the GTOCP1 control boxes). It will not work if you use the bottom connector.

Test Procedure

1. Start your PC. The keypad upgrade tool will run under Windows 95 or later.



2. Assuming that you downloaded with the default file location settings, select Start | Programs | Astro-Physics | Keypad Databsae Loader Ver 4.20 UP ROMS. The Keypad Database Loader Tool window will display. The white window should display two digits, one above the other, corresponding to the COM port number in the selection box. It will probably be two "1" digits. The Database for ROM Level Loading box will show the version number that your about to load the database for. If the box does not display 4.2, then this is not the correct Database upgrade tool.





3. Double check to be sure your cables are connected as described above, then turn on the power to your control box. Remember that the keypad cable is not connected at this point.



4. Set COM port selection. The number selected will display in the white box.



5. Click on Test Computer COM Port to Mount. Message should read "mount found". If not, check to be sure that your keypad is NOT plugged in. If if is, turn off the power to the control box, unplug the keypad and exit from the Keypad Database Load Tool. After 30 seconds, turn the power back on and bring up the Keypad Upgrade Tool again. Repeat this step. If you have an error and the keypad is not plugged in, select another COM port.
   
   When the "mount found" message appears, look at the entry in the white box. If it shows a series of zeros followed by a "#" sign (i.e. 00:00.0#), you have found the correct COM port. If #:GR# appears in the white box, then that COM port is connected to another device, perhaps a modem or digital camera, etc. If that is the case, try another COM port. Please click "ok" to move on to the next step.



6. Click the Check Mount Firmware button. The program will poll the GTO control chip to determine if the chip version number will support the upgrade procedure. Chips issued prior to version "C" (shipped prior to January 22, 2001) do not have the upgrade function. The white box will display the chip version number and "#" sign. Don't press the Send Controller Code to Mount button yet. Please read on.



7. If you have the proper chip, press "ok", then turn off the power to your GTO control box. Keep this Keypad Update window open in your web browser since you will use it later. DO NOT press any other buttons on the keypad just yet. Proceed to the Keypad Update section below.



8. If you get an error message, check all cables and connections. Then click the Check Mount Firmware button again TWO times (the first click will clear the buffer and you will see an error code, click it again). You will need to press "ok" at each of the prompts.
   
   
9. If the chip is an older version and fails this test, contact Astro-Physics to obtain a new chip. DO NOT attempt to continue this upgrade until you install the new chip. Otherwise, you will erase the old program with no means of installing the new one.
