DC Power Input

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 6-3.

Table 6-3. DC Power Input Connector Pin Assignments

Conductor	Description	Comments
Center Pin	16 Volts DC ±10%, 3.36 A	(Hosiden part number
		HEC3900-01-010)
Sleeve	Ground
		This connector is a
		EIAJ-RC5320A standard
		connector. See “DC Power Input
		Connector Pin Assignments” on
		page 48 for more details.

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.
