INFORMATION ABOUT HR2 COMMUNICATIONS AND PROGRAMMING:
1. Disrupted Communications
Communications between the HC and HR2 may be disrupted when the Configurator is being
used to configure certain data. This is analogous to all Viewers (TS7, Profile 700, etc) jumping to
the Home Page when certain modifications are performed. Communications to and from the
HR2s are disrupted from one to thirty seconds (or longer) depending on the number of HR2s in
the system and the change being made.
The worst case scenario is making changes (adding, deleting, changing size) to TV Icons being
used on the HR2. For example, when using all TV Icons and having 20+ HR2’s in the system,
HR2 communications will be lost for 2 minutes or more while the changes are being applied.
When communications is lost, HR2 button pushes will not work and the HR2 may display
“System Controller not found”.
Once the Configurator has completed its calculations, the HR2s will resume normal operations.
2. Heavy traffic may affect download times
When a download to an HR2 is in progress, the amount of traffic on the Wireless Router / Access
Point may affect the download times. Under extremely heaving traffic, downloads may fail and will
be restarted.
If experiencing problems downloading to multiple HR2s at the same time with heavy traffic, try
waking fewer HR2s at the same time.
3. Downloading new / modified TV Icons to the HR2
When TV Icons are changed, the system needs to recalculate data for each HR2 in the system.
A status message is displayed on the bottom status bar of the Configurator for each HR2 once its
data has been recalculated. The HR2s are processed in the order they appear on the Interface
Tab. When the last one has been processed, the system is now ready to download the new data
to the HR2s.
If all TV Icons are in use, it will take approximately 5 seconds to perform the calculations for each
HR2.
Be sure to wait till all calculations have been completed!
As each HR2 is awakened (by shaking or by key press), it will initiate a download of the new
data. On a wireless network with light traffic, there should be no problem downloading to eight
HR2s at the same time. If a download experiences problems, it will attempt the download again
until it succeeds.
In the worst case, if a download is not successful due to heavy traffic, the HR2 will abort the
download at this time. It will re-try either the next time it wakes up or when the TV Icons are
needed for display on the HR2 (“just-in-time downloading”).
