FOCUS CONTROLLER

TESTING

Back to  Observing Support Home Page

Use the following steps to bypass the ICE software program and communicate directly with the Galil DMC-100-10 controller.
The Galil, in turn, commands the focus system to move the detector.

SET UP THE TEST

  1. Exit the ICE program if it is running.  This releases the serial port connected to the Focus Controller.
  2. Type kermit.  The is a serial port communications program.
  3. Type set line  /dev/ttyz05.  This sets Kermit to the Focus Controller port.
  4. The Sun responds with "Warning, write access to lock directory denied" or some drivel like that.
  5. Type set baud 9600.  This sets Kermit to the right baud rate.
  6. Type connect.  This directs Kermit to start communicating with the serial port.
  7. Set the CAPS LOCK on.  The Galil needs all caps.
  8. Press the return key.
The Galil should respond with a full colon (:) If it doesn't, then the Sun and the Galil are not communicating.

TESTING THE GALIL AND FOCUS CONTROL COMMUNICATIONS

  1. Type GN?  The Galil should respond with the current gain of the system.  The response should be 08 as a default or 64 if ICE has already downloaded the PFC parameters.
  2. The ICE program changes various values in the Galil.  Here's a list of the changes.

MOVING THE FOCUS MOTOR

  1. Type PR 500.  This is the number of counts to move the Focus Motor.
  2. Type BG.  This tells the Galil to Begin Motor and run the number of steps you stored into PR.
  1. Type PR -500.  This is the number of counts to move the motor in the reverse direction.
  2. Type BG.  This tells the Galil to Begin Motor and run the number of steps you stored into PR.



TO EXIT THE TEST

  1. Type ^C.  Press and hold the Control key, then press C to tell Kermit to go off-line.
  2. Type quit.  To exit Kermit.
