Notice! If any version of the Model 2070 is to be powered by
the host interface, please refer to the host’s installation manual
and ensure that the combined power required by the host, and
the total of all the additional peripherals, installed both
externally and internally, does not exceed the power
specifications of the host apparatus
4.3 DTE (TERMINAL) CONNECTION
The V.24, V.35 or X.21 side of the Model 2070 Series units are
wired as a DCE and support a wide range of applications. You may
purchase adapter cables from Patton Electronics. If you would like to
construct your own interface cable, refer to the pinout diagrams in
Appendix D or contact Patton Electronics Technical Support: (301)
975-1007; support@patton.com;orhttp://www.patton.com for

4.4 POWER CONNECTION
The 120VAC U.S. wall transformer version supplies +5V regulated
DC up to 300mA. The variable 110/230VAC “international” version
supplies +5V regulated DC up to 2A. Either of these transformers
connect to the Model 2070 by means of a cannon jack on the rear
panel. The Model 2070 is powered-up as soon as it is plugged into an
AC outlet–there is no power switch.
4.4.1 120 VAC Power (US)
The 100-132 VAC adapter supplied with the U.S. version of the
Model 2070 is a wall mount type and may be plugged into any
approved 120 VAC wall plug.
