- 1100GTO with GTOCP4 Control Box (05-30-18) - PDF document - Current Version for mounts shipped starting in June 2016 and all previous 1100GTO mounts produced. We strongly recommend that ALL 1100GTO owners adopt this version as their manual (note that some aspects may not apply to earlier versions of the mount). Owners of older 1100GTOs can benefit from all that we have learned over the years by using this manual. Information on accessories, the servo system and polar alignment will be of particular value. See page 3 for more information about this manual. Note that the Astro-Physics GTO Servo Drive System has been given its own separate manual - see below.

- GTOCP4 and GTOCP5 Control Boxes -these files are useful for both
- WiFi
Poll for GTOCP4 and GTOCP5 Ethernet Application to
find current IP addresses and other network information.
It also can open the GTOCP4 or GTOCP5 webpage in IE. Requires AP
V2 ASCOM Driver and a serial or USB connection to the control box.
NOTE: We had removed the link to this .exe file earlier since it
had caused a problem with firewalls and anti-virus programs. It
is now back on the website as an encrypted ZIP file, and is in
a restricted area of the website. Both the download and the zip-extraction
will require the same password that you use for downloading Keypad
firmware. Normal Windows extraction is fine. A purchased copy of
WinZip is NOT required.
- Default IP Address
Calculator and Latitude/Longitude Coordinate Converter This
link has two handy tools:
** IP Address Calculator - will take the CPx serial number and return
the default IP address for the device. While the Wi-Fi poll and FindMounts
look at your actual system and find devices, this only does a basic calculation
without looking into your computer.
** Latitude/Longitude Coordinate Converter - Enter local coordinates in decimal degrees, and press Calculate Coordinates to get the Degree:Minute:Second format.
- Find Mounts Java Applet to find current
GTOCP4 IP addresses and other network information. Works for any computer - Windows, Mac or Linux running Java. Requires the Java Runtime Environment from Oracle (already found on many computers) This also was placed on the website as an encrypted ZIP file, and is in a restricted area of the website. Both the download and the zip-extraction will require the same password that you use for downloading Keypad firmware. Normal extraction is fine. A purchased copy of WinZip should NOT be required.

Servo Control Boxes. We strongly recommend that all owners of Astro-Physics
and OEM GTO mounts with GTOCP4 control boxes adopt this manual as
their primary reference for the GTO Servo Drive System. Owners of
older GTO mounts may also find useful information in this manual,
but be aware that not all the information will apply to the older
servo control systems. This is an ongoing project that we will try
to keep updated with all the latest developments. Please check back
often and compare the date following the link to the date on your
copy of the manual to stay abreast of the latest developments.
