Digi TransPort WR21 Handbook page 2

Introduction
When Digi began serving
the utility industry, Dire Straits
"
Money for Nothing" topped
the Billboard charts, the first
cell phone was hitting the market
(weight: 1.3lbs, talk time: 1hr)
and Ronald Reagan was president.
We've come a long way since 1985, but the qualities that we started with—dedicated engineering, responsive tech
support and an industry-leading warranty—are the same qualities that allow us to continue serving the largest
investor owned utilities as well as the smallest rural electric cooperatives.
On the following pages we provide information on connecting common C&I meters with Digi TransPort® 3G and 4G
LTE cellular routers, as well as information on installation, cabling and antennas.
Special thanks are due to Digi customers in meter shops across the world. Thank you for sharing what you've
learned as you have used Digi product in the field.
