You can download a terminal program to test the communication of telescope mounts. for example, with this program you can send commands to Merlin mount to check the connection through Bluetooth interface.

Using this program may require basic technical knowledge about serail port communication and telescope mount protocols.

This program is freeware and can be downloaded from here: Terminal.zip

From here you can download device drivers needed by Ursa Minor program or some of our hardware accessories.

USB-serial driver (For Ursa Minor Autoguider interface and combined USB interface cable)

Virtual serial port driver

This driver can emulate a virtual com port pair (these are software ports, no hardware required). With this com port pair the Ursa Minor Program can make a connection with an autoguider program. The result: Using single cable for auto guiding and telescope controlling. Download: com0com-2.1.0.0-i386-chk.zip
