4.2 DTE (TERMINAL) CONNECTION
The Model 2400 is wired to connect to a DTE. If your terminal
device is DCE, contact Patton Electronics Technical Support: (301)
975-1007; http://www.patton.com; or, [email protected].
for specific installation instructions.
The Model 2400 is designed for direct connection to the DTE
without the use of a cable and is available in two interface options --
RS-232/V.24 and V.35. If it is necessary to construct or purchase your
interface cable, refer to the pinout diagrams in Appendix D.
4.3 POWER CONNECTION
The Model 2400 can be powered from the supplied AC power
source, from DC power supplied to the power supply jack or directly
from the local RS-232/V.24 (Model 2400/A) or V.35 (Model 2400/C)
interface. This section describes the available power options.
120 VAC Power (US)
The 120 VAC adapter supplied with the standard version of the
Model 2400 is a wall mount type and may be plugged into any
approved 120 VAC wall plug.
230 VAC Power (IEC)
The Universal Input Adapter adapter supplied with the
“International” version of the Model 2400 is equipped with an IEC-320
shrouded male connector. This connects with one of several available
country-specific power cords (see the ordering information in Appendix
C). You may purchase these power cords from Patton Electronics, or
from a local vendor of your choice.

4.3.2 DC POWER CONNECTION
You may bypass the AC wall adapters and supply DC power directly
to the Model 2400 power supply jack or via the DTE Supplemental
Power Input pins. The AC wall-mount transformer must not be
connected when the Model 2400 is powered by DC.
DC Power Supplied to Power Jack
You may supply DC power directly to the power supply jack. DC
power supplied must be 5VDC ±5%, 200mA, center positive, and can
be supplied via a barrel type plug with 2.1/5.5/10mm I.D./O.D./Shaft
Length dimensions.
Interface Power
The Model 2400 may also be powered by means of the RS-
232/V.24 (Model 2400/A) or V.35 (Model 2400/C) interface signals. DC
Power supplied to the interface pins must be at +5VDC (±5%), 200mA.
See Sections 3.2.1(Model 2400/A) and 3.2.2 (Model 2400/C) to
configure the unit to receive interface power.
NOTE: DC power source must be SELV (Circuit, Safety Extra Low
Voltage) specified. (See CENELEC EN60950, Section 1.2.8.5)

WARNING: The Model 2400 will be damaged and will not be
covered by warranty if any other power supply input than 5VDC
±5% is used with the Interface Power Option.
