Here is a Connector Cable Set for Autostar-DS series, ETX series, and LX 90. #505 Connector Cable Set.
Telescope Control:Use a personal computer (PC) to directly control a Meade Autostar-compatible telescope through the use of an astronomical software program with telescope control capabilities such as Meade Epoch 2000sk Sky Software.
Download from a PC:Download a new version of the Autostar software or object information (e.g., new satellite orbital parameters) from Autostar Downloads page through a PC to Autostar.
Download and Clone from Autostar:Transfer user-defined object information or new Autostar software from one Autostar Computer Controller to another.
Here is what I have:
3-foot, 4-pin to 4-pin cable
6-foot, 4-pin to 6-pin cable
6-pin to RS-232 serial interface adapter.
The 3-foot cable connects two Autostars, while the 6-foot cable connects an Autostar and a PC using the interface adapter.
