POWER OF ATTORNEY

	I, Larry A. Kraft, hereby authorize and
designate each of James E. Nicholson, Amy C. Seidel,
John A. Haveman, Joshua Colburn, Michael N. Molepske
and Julie M. Regnier signing singly, as my true and lawful
attorney-in-fact to:

	(1)	execute for and on my behalf, in my capacity as
an officer and/or director of Digi International Inc. (the
"Company"), Forms 3, 4 and 5 in accordance with Section
16(a) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and the rules and regulations
promulgated thereunder;

	(2)	do and perform any and all acts for and on my
behalf which may be necessary or desirable to complete and
execute any such Form 3, 4 or 5 and timely file such form
with the Securities and Exchange Commission, any stock
exchange or similar authority, and the National Association
of Securities Dealers; and

	(3)	take any other action of any type whatsoever in
connection with the foregoing which, in the opinion of such
attorney-in-fact, may be to my benefit, in my best
interest, or legally required of me, it being understood
that the statements executed by such attorney-in-fact on my
behalf pursuant to this Power of Attorney shall be in such
form and shall contain such terms and conditions as such
attorney-in-fact may approve in such attorney-in-fact's
discretion.

	I hereby further grant to each such attorney-in-
fact full power and authority to do and perform any and
every act and thing whatsoever requisite, necessary, or
proper to be done in the exercise of any of the rights and
powers herein granted, as fully to all intents and purposes
as I might or could do if personally present, with full
power of substitutes or revocation, hereby ratifying and
confirming all that such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall
lawfully do or cause to be done by virtue of this Power of
Attorney and the rights and powers herein granted.  I
hereby acknowledge that the foregoing attorneys-in-fact, in
serving in such capacity at my request, are not assuming,
nor is the Company assuming, any of my responsibilities to
comply with Section 16 of the Exchange Act.

	This Power of Attorney shall remain in full force
and effect until I am no longer required to file Forms 3, 4
and 5 with respect to my holdings of and transactions in
securities issued by the Company, unless earlier revoked by
me in a signed writing delivered to the foregoing
attorneys-in-fact.  Notwithstanding the foregoing, if any
such attorney-in-fact hereafter ceases to be at least one of
the following: (i) a partner of Faegre & Benson LLP or (ii) an
employee of Faegre & Benson LLP, this Power of Attorney shall
be automatically revoked solely as to such individual,
immediately upon such cessation, without any further action
on my part.

	I hereby revoke all previous Powers of Attorney
that have been granted by me in connection with my
reporting obligations under Section 16 of the Exchange Act
with respect to my holdings of and transactions in
securities issued by the Company.

	IN WITNESS WHEREOF, I have caused this Power of
Attorney to be duly executed as of this 21st day of
April, 2010.
