Optec Remote Keypad for Optec TCF-S/TCF-S3 Focusers

Optec Remote Keypad for Optec TCF-S/TCF-S3 Focusers
Item # OP-17680
  • Remote IN/OUT push-button keypad for Optec TCF-S or TCF-S3.
  • For manual control and LEARN or other serial operations.
  • Connection is hot-swappable so temperature probe or keypad can be connected at any time.
  • Includes 3 ft. of cable & version 2.30 firmware.


The plastic control box for the TCF-S focuser was never intended for frequent use at the telescope using it in a manual operating mode. The intended use was for complete computer operation with the control box located in some safe area near the computer. With three cables going to the control box, it was difficult to use as a hand paddle in any case. To allow manual control of the TCF-S and TCF-S3 at the telescope, a remote keypad with IN and OUT pushbuttons is available. The all aluminum device comes with a 3-foot cable (other lengths are optional) which plugs into the temperature probe connector located on the focuser. Neither the serial control or auto temperature compensation modes of the TCF-S focuser are operational when the remote keypad is in use. This keypad accessory is for manual hand operation of the focuser only. The connection is hot swapable so that the temperature probe can be plugged back in and normal TCF-S operation resumed at any time without a reboot. The remote keypad measures 1 x 1 x 6 inches and has two pushbuttons for IN and OUT functions. A stainless steel hook allows the unit to be stored by hanging on any available handle such as the hand hold on many Meade telescopes.

A classy product
Optec makes beautiful stuff. The machining is precise and red anodizing very SoftwareBisque-ish, which I love. The S-Video style cable connector is robust. In-out buttons comfortable under thumb. A must have accessory for the TCF-Si (new integrated version) and other focusers in the TCF line.
