APPENDIX E
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)
