REQUIREMENTS
It is important to understand that your control box and keypad both have software that enable them to function and to
communicate. Each time you upgrade your keypad, you will also need to ensure that your control box has the appropriate
version so that all of the necessary commands are available.
The upgrade instructions will specify the minimum required control box software version. The Keypad Loader Utility will
also query the control box to be sure that correct version is present. before you begin the load.
New control box and keypad software versions can be downloaded from this link:

What Mount Control Box Do I Need?
●
The GTOCP4 and GTOCP5 control boxes have the computing power and required commands to use version 5 of the
keypad. Regrettably, the older control boxes (GTOCP1, GTOCP2 and GTOCP3) will not be able to use keypad with
upgraded v5.xxx software. Version 4.19.3. is recommended for these older units.
●
Your GTOCP4 or GTOCP5 must be upgraded to the software version specified in the download instructions.
Can I Upgrade My Present Keypad?
●
Keypads with serial number 1565GTO or earlier that have the original 256K circuit board cannot be used with the
v5.xxx firmware, as they lack the memory capacity. If you have a keypad with a lower serial number that has been
repaired, it may have the required memory.
●
Two of the buttons in the lower row of the newer keypads have different lettering on them.
The FOCUS button has
been changed to the RECAL button. The button labeled RA DEC REV will actually function as an ENTER
button. The RA DEC REV function will now be accessed through the +- button. The MENU button has
been relabeled to include ESC.
If you load v5.xxx onto an older keypad, you can continue to use your original buttons and simply
memorize the new function. Alternatively, you may send your keypad to Astro-Physics to be upgraded the
button pad. Contact Astro-Physics for additional information.
