Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 65
Read access is the lowest access level. A customer with read access may not make
any changes to the system. Read access allows one to view measurement readings,
view status, and view setup, and the like.
Maintenance access
Maintenance access provides everything that read access does, plus the ability to
calibrate sensors, clear status, reboot unit, and other station maintenance related
functions.
Full access
Full access provides complete access to the station.
Each tier has its own password. Access granted depends on the password entered.
The default passwords are SUTRON1 for read access, SUTRON2 for maintenance access, and
SUTRON3 for full access. Please change ALL THREE passwords when securing your system.
Blank passwords are NOT allowed. All ASCII bytes are allowed except comma, equals, and white
space. Passwords may be up to 19 bytes long.

Protection may be set to one of the following:
