Description

Unit Up Time

[RO]

Displays the elapsed time the unit has been running continuously

since its last reboot.

Unit Information

Opens the Unit Information page, which provides details about the
unit’s current operational firmware.

Boot From

Determines which version of the IP Module firmware (including

Application, FPGA, and FFPGA) will be loaded upon boot-up. The

possible options are:

0 (Latest) – Boots the newest firmware package based upon date.
1 (Image1) – Boots the firmware package loaded into the first slot

in permanent storage.

2 (Image2) – Boots the firmware package loaded into the second

slot in permanent storage.

Upgrade To

Determines which installed firmware package (including Application,
FPGA, and FFPGA) that the IP Module will overwrite when upgrading

with a new firmware package. The possible options are:

0 (Oldest) – Overwrites the oldest firmware package based upon

date.
1 (Image1) – Overwrites the firmware package loaded into the first

slot in permanent storage.

2 (Image2) – Overwrites the firmware package loaded into the

second slot in permanent storage.

Codecast Multicast Address

Configures the IP Multicast Address for the Codecast protocol. The IP
Module has the ability to get the firmware updates installed on multiple

units using the Codecast protocol, making unit upgrades easy in

bigger networks.
