FREQUENTLY ASKED QUESTIONS

Q: What is the passkey of my BETI?
A: The passkey is “12345” (please input the passkey without quotes).

Q: How long do the batteries last?

A: That depends on a number of different factors – type of encoders used, operating temperature, type of batteries. For example, a pair of NiMH, 2700mA freshly charged batteries will last approximately for four hours at 25oC when connected to a pair of S2 optical encoders from US Digital (http://www.usdigital.com/).

Q: Can I use non-optical encoders?
A: No, the firmware processes pulses from standard quadrature optical encoders such as the ones manufactured by US Digital.

Q: Can I change the passkey of my BETI?
A: No, the passkey is inbuilt and cannot be changed.

Q: Do I need to pair BETI with my PDA/PC every time I use them?
A: No, you need to pair BETI with your PDA/PC only once unless you delete BETI from trusted devices list on your PDA/PC.

Q: Does BETI use external power when both external power and batteries are inserted?
A: BETI uses power source selected by the switch ‘Power mode’. It will use either external power or batteries’ power but not both at the same time.

Q: Does BETI have a built-in charger for the installed batteries?
A: No, BETI does not charge the batteries when the external power is connected to it. BETI operates from either external power or from the installed batteries.

Q: How can I determine the resolution of my encoder?
A: Just multiply the CPR (counts per revolution) of your encoder by four and then multiply the result by the ratio of the gears (if you have any) it is connected to your telescope.
