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. You must also use a "straight through" (as opposed to a "null modem or crosswired") serial cable.

Test Procedure

1. IMPORTANT: Your keypad CANNOT be set to Auto-Connect YES for this upgrade. If your current version has the Auto-Connect feature, set it to NO or EXT.



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



3. Assuming that you downloaded with the default file location settings, select Start | Programs | Astro-Physics | Keypad Upgrade Tool + V4.20 ROM. The Keypad Update 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 ROM Level Loading box will show the version number that you about to load. If the box does not display 4.20, then this is not the correct upgrade tool.





4. 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.



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



6. 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 Upgrade 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.



7. 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.



8. 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.



9. 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.
   
   
10. 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.

Keypad Update

1. The power to the control box should be off. If not, turn if off.
2. Plug in the keypad and be sure that the power cable is connected to the GTO control box and locked in place. The motor cables do not need to be attached.
3. Place the keypad on a solid surface and press any three buttons (except stop) simultaneously and hold them down. We call this a "three-finger salute.". As you are holding these three keys, apply the power to the control box.
4. A new display will appear on the window of the keypad. At this point, release the three buttons. Then, press the West button to indicate YES for the next four windows. The last window requesting to Test Flash must be responded with NO by pressing the East button. This will erase the current program. These are the screen displays and the responses (note, the display says "FN=No", however you will press the "E" button):
   
   "Load defaults" - Choose Yes (West)
   "Are you sure" - Choose Yes (West)
   "Clear flash" - Choose Yes (West)
   "Are you sure" - Choose Yes (West)
   "Test flash" - Choose No (East)
5. Once you have completed the previous step, the keypad will be placed in a ready-to-receive mode. A blank window with the blinking cursor in the upper left corner of the screen will indicate this.
6. Look back to the Keypad Upgrade Tool window on your PC. Press the Send Controller Code to Keypad button. The Keypad Loader Pre-Load Checklist will appear. Review and check all boxes, then press Continue.




7. You will hear a series of beeps from the keypad as uploading begins, but will get no audible feedback during the rest of the upload. From this point on, the upload can take anywhere from 20 minutes to 35 minutes. Do not remove the power from the mount. Do not try to run any other application during this time. If you happen to check the task manager of your OS, it will state that the program is not responding, however it really is running properly, just slowly. Since the program must run through the control box into the keypad, it cannot run very fast. Make yourself a cup of tea (or your favorite beverage).
8. As the upload progresses, the white display box within the Upgrade Tool Utility will display a few lines of code, then go dormant for quite a few minutes. Don't worry, the upload is working properly. New code will display periodically, then pause again. If you have any difficulties with the download, please write down the first 10 lines that appear in the box so that we can help to diagnose the problem.
9. When the upload is complete, the Keypad Controller Post-load Checklist will appear on your computer screen. Please follow each step of the process carefully. This part of the process will set all personal settings to the default settings. This is necessary because of the storage location of this information has changed. We provided checkboxes to help you keep your place. If you accidentally press the wrong button on the keypad, remove power to the control box and follow the steps on the post-load checklist again.
   
   



10. Your GTO keypad is now updated to the new EPROM code and is ready to use. Turn the power to the control box off, wait 30 seconds, then turn back on. If the location selection screen comes up first, enter 0 and press GOTO. Then, press Resume from Park to get to the Main Menu.
    
    If the keypad is locked up on the Astro-Physics 4.20 screen, it is likely that Auto-Connect was set to YES prior to the upgrade. Please follow the instructions below to resolve this issue.



11. Please refer to the 4.1x Information Manual for further instructions.
