YZ Connect
Overview
YZ Connect is a solution for remotely managing mission-critical odorization programs. YZ Connect
consists of a cellular gateway and a web/app based software that talks Modbus with YZ Systems
odorizers. It is a secure, easy, and scalable method to monitor all odorization stations from a
single app and/or web interface.
YZ Connect, compatible with both NJEX pneumatic and NJEX ZEO odorizers, communicates with the
odorizer via Modbus, pulling a snapshot of data to the cloud every 10 minutes. Grab snapshots
faster when needed be selecting the “Get Status” button in the upper left corner of the snapshot
page. Remotely monitor all connected odorizers and look at the critical performance parameters
from your truck, house, office, or wherever you need to!
With an ADMIN level account or higher, users can control the odorizer and change parameters remotely.
USER level accounts only have the ability to remotely monitor equipment and cannot control or make
parameter changes.
YZ Connect Login/Account
The YZ Connect administrator(s) at your company are responsible for adding each user. After your
administrator adds a user, the user will receive an activation email from YZ Connect. After
following the steps in the activation email, users can login via the website or mobile apps.
Admins should reference the YZ Connect Admin User Manual for details on managing/organizing
your companies odorizers, adding employees/customers and more.
