Keyboard/Mouse Ports 5-5
Keyboard/Mouse Ports 5
The keyboard/mouse ports on the mini-dock can be used with most PS/2-style keyboard and mouse
devices. The system determines whether a keyboard or mouse is connected automatically and activates
the appropriate signals on the port as shown in Table 5-6.
Note:
This port is compatible with most PS/2-style keyboards. Conventional PS/2-style keyboards are powered
by 5 volts on pin 4.
Pin assignments for the keyboard/mouse port on the pen tablet are shown in Table 5-6.
DC Power Input 5
The DC power input connector connects to the AC adapter or auto adapter to power the pen tablet. The
DC power input connector is a two-conductor connector with a center pin and sleeve. Pin assignments for
this connector are given in Table 5-7.
When a DC power source is connected to the DC power input on the pen tablet, circuitry built into the
pen tablet provides protection against reverse polarity and overvoltage.
