    Safety measures for the stops Read the warnings on page 5. • The fixed stop (5) on the upper part of the column, and the adjustable stop (6) beneath the motor housing, limit the movement of the motor-focus system. • In addition, there is an end-switch (7) on top of the motor housing and another one beneath it.

  • Page 10: Handswitch

    When the system is first switched on, the rapid focusing mode is active. • In addition to a standard PC with RS232 interface, you need a PC interface kit from Leica. • The individual functions and commands are described in a separate user manual for the PC interface kit.

  • Page 18: Interface Parameters

    Control Concept The motorized focusing unit can be connected by means of the PC Interface Kit to any standard PC, Macintosh computer or terminal with RS232 interface from which it can then be controlled. The manual control unit is connected to the motorized focusing unit via an internal bus (CAN-bus).
  • Page 19 Interface cable: Optional connection for Footswitch Connect to Connect to Leica Motor-Focus System PC - Serial Interface ”Control 1” RS232 If the cable is too short a screened zero modem cable can be used as an extension (9-way, with pins connected 1 to 1, 2 to 2, etc. ).

  • Page 20: Unit Identifier

    The unit identifier must be sent as the 1st parameter. Maximum 2 significant digits (range 1 to 99): 70 for MOTOR FOCUSING UNIT (MST31/34) 71 for MANUAL CONTROL (MHS1) The unit identifier may contain leading zeros. However, the entire unit identifier must not consist of exactly 5 digits.

  • Page 21: Terminating Characters

    Terminating characters The following terminating characters are accepted: <CR> (carriage return) or <CR><LF> (carriage return, line feed) Leading zeros Leading zeros can be inserted in the case of parameters. Sign The sign must be positioned directly before the parameter (without separator), however the parameter can include leading zeros.

  • Page 22: Control Commands (Manual Control)

    Parameter: none Return: Short designation of the unit ”70 01 LEICA MST 31/34” Comment: The name of the unit is given in plain text (ASCII). Note: If several units are connected to the motorized focusing unit via the internal bus the names are not returned.

    MOVE DOWN Lowers the stereomicroscope (move command) Command code: 70 011 <CR> Parameter: none Return: none Comment: Lowers the stereomicroscope at the set speed down to the lower limit switch or lower limit (see also MOVE UP). MOVE STOP Interrupts movement, stops the stereomicroscope. Command code: 70 012 Parameter:...

  • Page 24: Move Relativ

    Return: none Comment: The unit used for the position is the µm (micrometer 0.000 001 m). The reference (zero reference point) is in the position at which the unit is switched on, or in which the SET REFERENCE command was executed. Note: The user must ensure that the range is restricted (possible distance of travel).

  • Page 25: Set Velocity

    Comment: The momentary absolute position is sent. If a SET REFERENCE (70 013) is not performed the absolute position refers to the position at power-on. Range: ±2.147.483.647 Example (for RS 232): Momentary absolute position = 7.25 mm host sends: 70 032 <CR> host receives: 70 032 7250<CR>...
