Comtech EF Data Vipersat Load Utility v3.5.x - Manual (Page 67)

Chapter 3 - Using VLoad — Vipersat Mode 3-43
Base Modem Mode
The Put options available in the Image box of the Put dialog allow the Save To
image slot of the modem to be designated for replacement of the application .bin
file:
• Image #1 – The image file will be written to the target unit’s slot with the
label of Image #1.
• Image #2 – The image file will be written to the target unit’s slot with the
label of Image #2.
The Put operation transfers the selected image file to the designated Save To
image slot by writing it to the target unit’s flash memory. This is non-volatile
memory used by the modem’s Base Modem board to persistently store its firm-
ware. These stored images are not currently running on the unit, but can be
selected from flash memory by command as required. Refer to the “Image
Selection” section on page 3-15 for additional information.
Clicking the OK button sets the values to be used and initiates the Put action.
The Progress area of the main window will display the transfer progress status.
The Put Base Modem Image is a three-step process:
1) The file is transferred from the workstation to the unit’s router card RAM.
2) The router then transfers the file to the Base Modem.
3) The data is written to flash memory on the Base Modem board.
Note that this complete process may require up to several minutes, depending
on the data transfer rate as well as the type and the number of units selected.
Following a successful Put operation, executing a Hard Reset will command
the modem to reboot and load the new image.
Select Base Modem Image / Codecast Select Base Modem Image
Clicking the Select Base Modem Image / Codecast Select Base Modem
Image button displays the dialog window shown in figure 3-40, allowing the
selection of what image to run in the target modem on the next Reset.
This function is operable for either a single unit or multiple units. If multiple
units are selected for a Select Base Modem Image, the Same For All Selected
Units check box will appear, providing the option to perform this action on the
group using the same specified settings.
For a Codecast Select Base Modem Image, the Multicast Address specified
determines the modem group to be targeted. By default, the address 239.1.2.4
appears since this is the default Codecast Multicast Address of Vipersat units
when they are shipped from the factory.
