3.3 CONNECTING POWER
The Interconnecting cables shall be acceptable for
external use and shall be rated for the proper applica-
tion with respect to voltage, current, anticipated tem-
CAUTION perature, flammability, and mechanical serviceability.
The Model 2173 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 2173. 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 2173) 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.
4.0 CONFIGURATION
