I really don't think so. The CH D100 was made by Toshiba and used the same software for the EX20 and EX40 processors. The TiSoft software is used for Texas Instrument processors, which I think were made by Koyo.
Here is a link to Toshiba for EX Manuals and Utility Software.
I can't recall if the CH D100 is the same as a Westinghouse PC500, or a Siemens S5 100U. If it acts the same, FasTrak's Siemens S5 software will support it. I can get you a demo to try, and a full working copy is not too expensive. [email protected]
