Troubleshooting
1. This unit is designed to work with PS/2 keyboards and mice. XT (84 key) and AT key-
boards will not work. Serial mice will not work.
2. Some Notebooks, notably the IBM Thinkpad and Toshiba Tecra, have trouble when
their mouse and keyboard ports are used simultaneously. To avoid this, only connect
the mouse port or the keyboard port. If you connect the mouse port, you will need to
use the notebook's keyboard when the notebook becomes the active computer.
