          Re:  Registration Statement on Form S-1
               Covering the Registration of
               Shares of Common Stock of
               Communications Systems International, Inc.


Ladies and Gentlemen:

     We have acted as counsel for Communications Systems International, Inc., a
Colorado corporation (the "Company"), in connection with the registration for
sale of shares of the Company's Common Stock (the "Shares") in accordance with
the registration provisions of the Securities Act of 1933, as amended.

     In such capacity we have examined, among other documents, the Registration
Statement No. 333-47045 (the "Registration Statement"), covering the
registration of the Shares.

     Based upon the foregoing and upon such further examinations as we have
deemed relevant and necessary, we are of the opinion that:

     1.   The Company is a corporation duly organized and validly existing under
the laws of the State of Colorado.

     2.   The Shares have been legally and validly authorized under the
Company's Articles of Incorporation, as amended, and, when issued and paid for
in accordance with the terms of the underwriting agreement, will constitute duly
and validly issued and outstanding and fully paid and nonassessable shares of
the Company.
