Designing Compatible Peripherals for the High-Usage Contacts
This addendum provides supplemental information to the
Stylistic 2300 Technical Reference Guide
for
engineers designing peripherals for the Stylistic 2300 pen tablet which connect to the pen tablet using the
high-usage contacts.
High-Usage Contact Signal Assignments
Signal position assignments for the high-usage contacts on the pen tablet are given in Table E-1. The
keyboard and mouse signals are compatible with PS/2-style devices.
Disclaimer
Design issues discussed in this addendum are general design
guidelines and considerations for engineers. Designing
compatible peripherals requires thorough engineering and
testing by the designer.
Fujitsu Personal Systems does not warranty, and claims no
liability for, damage to peripherals or damage to the pen tablet
resulting from using peripherals not made by Fujitsu Personal
Systems.

When grounded, this signal indicates (to the pen tablet)
that a peripheral device is connected to the high-usage
contacts. This enables the keyboard and mouse signals of
the high-usage contacts. This signal should be connected
to ground by peripherals that connect to the high-usage
contacts.
