The Keypad is a self-contained handheld computer that allows you to control all essential telescope functions and includes an extensive database of objects. We have designed this unit to be as intuitive and easy to use as possible, while filling it with terrific features to make your observing session productive and pleasurable. Most buttons are assigned to one function only. You do not have to remember shift key patterns or complex keystroke sequences. The directional buttons are shaped like arrows to help you find them in the dark without looking at your keypad. The stop button is readily accessible if you need to cancel any slewing request immediately. The menu system is very easy to navigate. Each 4-line screen will display several choices which correspond to a number button. Simply press the number button to initiate the command, e.g. "1=M, 2=NGC." When you press "1" the Messier entry screen will display and you can enter the number of the object that you wish to see. Press GOTO, which will cause the mount to slew. The <PREV and NEXT> buttons will allow you to scroll quickly through the lists of common names or from one menu to another. You will be very pleased with the intuitive operation of this controller. There are no complicated sequences of keystrokes to remember. It is so easy to use that even if you don't use it for a few months, you will feel at home with the Keypad very quickly. The Keypad can be used with all versions of the Astro-Physics GTO Control Boxes: GTOCP1, GTOCP2, GTOCP3 and GTOCP4. Compatible mounts include: Mach1GTO, 1100GTO, 1600GTO, 3600GTO and the older 400GTO, 600EGTO, 900GTO and 1200GTO. The Keypad connects to the control box via a 15' coiled cable. |

Keypad Protector (KEYPRO) The Keypad Protector is included with all Keypads, however it can be purchased separately. The KEYPRO Keypad protector (shown in the keypad photo above) is a heavy-duty molded rubber casing with a full 1/4" thickness on all impact surfaces. If you accidentally drop your Keypad, the rubber casing will absorb much of the blow. Your display, Keypad, electronics and the case itself will be protected from damage. In addition, the rubber prevents the keypad from sliding when placed on a table or other flat surface and the Keypad will feel secure in your hands as you observe. The KEYPRO also offers protection during transport and storage. The black case is designed with cutouts for the cable and retractable hanger. Instructions: Removing and Installing the KEYPRO Keypad Protector for all Keypads. |
As of this writing, we have produced extension cables up to 50' that work properly. We cannot guarantee longer cables. The two dashes in the part number will be replaced by the number of feet in the cable when you place your order. Mounts that can use this cable: All GTO mounts. |
