Interfacing to the Plan Wheel XL
(This information is intended for developers of commercial software
programs. Persons interested in using the Plan Wheel XL for their
individual use should refer to Application Note
AN-08, "Linking the Plan Wheel XL to Your Computer".)
There are a number of ways to interface the Plan Wheel XL (or Plan
Wheel PC) to your software program. The following are the most popular
methods of interfacing to the Plan Wheel XL, beginning with the quickest
and easiest "pre-packaged" solutions, and progressing to
the more time-consuming "do-it-yourself" solutions.
Scalex Ready Connect (formerly TakeOff for Windows) is a complete
software solution which provides a "bridge" between the
Plan Wheel XL and any Windows program. As such, it can be used without
any modification to your program.
In operation, Ready Connect appears on the computer screen as a small
window which is "always on top" of your program. It allows
the user to change scale factors and other scaler settings directly
from the computer. After doing a take-off, the user clicks on a button
on the Ready Connect Window and the displayed take-off results transfer
directly into your program at the insertion bar.
Ready Connect works with Windows 3.1, 95, 98, NT and 2000 and is
sold complete with disks and manual. Contact Scalex sales for current
pricing and discounts.
Scalex Connector 1.0
Scalex Connector 1.0 is a 32-bit ActiveX-based driver which provides
you with complete, low-level control over the Plan Wheel. Just drop
the control on a form in any 100% OCX compatible container such as
Microsoft Visual Basic, Microsoft Excel VBA, or Visual C++. Also compatible
with Borland Delphi. You can then set and retrieve all of the Plan
Wheel attributes via the control properties. Scalex Connector is transparent
to your user and requires no serial port programming.
This royalty-free control is available from Clearlogic Corporation,
Scalex’s third-party software developer. The control costs $450.

If you are interfacing to a DOS program, TakeOff is a pop-up TSR
program similar in operation to Ready Connect. Hot-keys are used to
enter scaler take-off results into your program at the cursor or to
pop-up the TakeOff Utility window.
TakeOff requires just under 64K of memory. As with Ready Connect,
you are not required to modify your program.
To interface the Plan Wheel XL to any MacIntosh program, use Scaler
Mac. Similar in function to Ready Connect, you are not required to
modify your program.
Serial Interface Specification
And finally, if you wish to get right down to the "bit level" and
write your own driver, the complete Plan Wheel Serial Interface Specification
is available in written form at no cost. Just contact Scalex sales
