PATTON MODEL 2702

POWER SUPPLY INTERFACE

Via Main 5VDC power jack (J1)

Center Pin:	5VDC @ 300 mA
Outer Barrel:	Ground
Barrel Plug:	2.1/5.5/10mm I.D./O.D./Shaft Length dimensions.

Jumper Position for Power via DC Power Jack (default):

Via Auxiliary Power Supplied to Pin KK on V.35 connector

DC Power supplied to pin KK must be 5VDC ± 5%, 300mA minimum.

Jumper Position for Power via Pin KK:

NOTE: Model 2702 is factory configured to accept power from the enclosed DC wall adapter (See Sections 4.3.1 and 4.3.2 above). If you wish to supply power via pin KK on the interface, you must change the setting of the power supply jumper on the printed cir- cuit board. All power sources must be SELV (Circuit, Safety Extra Low Voltage) specified. (See CENELEC EN60950, Section 1.2.8.5)
