3.3 CONNECTING POWER
The Model 2151 does not have a power switch, so it powers up as soon 
as it is plugged in.
An external AC or DC power supply is available separately. This connec-
tion is made via the barrel jack on the rear panel of the Model 2151. No 
configuration is necessary for the power supply (See Appendix B for 
domestic and international power supply and cord options).
DC power (supplied via the power supply jack to the 2151) must meet 
the following requirements; DC power supplied must be regulated 
+5VDC ±5%, 1.0A minimum. Center pin is +5V. The barrel type plug has 
a 2.5/5.5/10mm I.D./O.D./Shaft Length dimensions.
