APPENDIX D: PRODUCT DEVELOPMENT

Main Milestones in Product Development:

•Dec. ʼ01: V1.00: Product launching.

•Apr. ʼ02: V1.02: Support under WinNT/2K/XP (refer to section 3.1.1 & appendix C).

•May ʼ02: V1.03: In addition to the OCX, a DLL is supplied too (WinNT/2K/XP only).

•May ʼ03: V2.00: New feature: Option to request a snapshot of the position counters in real-time, using a hardware input (in addition to the veteran software function for this operation). The new feature uses the last input (input #11); hence, input #11 is no longer operational as a general input, and there are now only 10 (vs. 11 before) general inputs. For details, refer to section 1.2.1 and appendix A.

•Oct. ʼ03: V2.01: Better support for installation on WinXP (though it was possible also before based on the procedure for Win2K).
