TCF-S Information
Navigator
The control box for the TCF-S and TCF-S3 are the same. The control box powers the stepper motor, reads the temperture sensor, provides bi-directional serial communication with the PC and allow the user to control and read the state of the focuser remotely. However, it is not intended to be used as a hand control because of the need for three cables to be connected to it. These include: power cable, PC serial cable and control cable to the focuser. For hand operation, the remote keypad is recommended.
For normal operation, the two slide switches are placed in the RUN and MANUAL position as shown in the diagram. To teach the focuser a new temperature coefficient, the RUN switch is placed in the LEARN postion and the MANUAL swtich is placed in AUTO A or AUTO B.
The position of the focuser in units of "steps" is shown on the DRO display. For the TCF-S, position is shown from 0 to 7000 steps which corresponds to a maximum travel of 0.60 inches. For the TCF-S3, the range of the DRO is 0 to 9999 steps which corresponds to a maximum travel of 1.00-inches.
