Schematic; SE108-21 (Hayes Modem Cable)

Cable; 10c/RJ45 male to DB-25p male

Note that all X-Rite 400's, 900's, SP's, MA's, DTP, and Photo scanning densitometers use an RJ45 (type) female interface connector. While identical in dimension to a true RJ45, the interface in X-Rite's products is a 10 circuit design.

The interface cable described below allows X-Rite 891/892 densitometers to be directly attached to many Hayes type modems. Specifically the modem must be equipped with a DB25s (female) connector. In addition it must be electrically equivalent to a "standard" Hayes (DCE) interface (see Related SUpport).
