| The H151 controller allows X and Y axis control using a joystick and focus by two push buttons. It also contains a microprocessor and instruction set which enable the user to control the stage from a host computer via a RS232 port. These are in the form of low level commands sgh as: "G.1000.2000" which will move the stage to X=1000 and Y=2000 steps from stage zero, or "A" which initiates AUT0 focus. A complete list of these instructions isgiven in the H151 manual.
The H 1 51 is designed for people who already have a P.C. or microprocessor as part of theirequipment and need a simple method of controlling the stage and focus movement without writing motor control and position data programmes and placing additional "ouerhead" on their system. |
