page 3-23 for putting files to the Vipersat router board portion of the
modem.
This function is operable for either a single unit or multiple units. If multiple
units are selected for a Put Base Modem Image, the Same For All Selected
Units check box will appear, providing the option to perform the Put to the
group using the same specified settings.
For a Put Base Modem Image, the File box at the top of the window is read-only
and shows the path and file name (designated in the File Selection box of the
main window) of the binary file to be Put to the target Vipersat modem.
For a Codecast Base Modem Image, the file path and name can be edited, if
desired.
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.
Because Codecast utilizes multicast with no verification, the Codecast Base
Modem Image dialog displays the following IP multicast parameter settings:
• # Passes – the number of transmissions to each unit (default is 3).
• Pause – the time, in seconds, between transmissions (default is 5 sec).
• Time to Live – the maximum number of router hops/seconds to reach a
unit before the data packet expires (default is 10). This parameter prevents
possible looping of the packet transmission in the network.
• Local Address – the address of the network interface card (NIC) on the
local host machine to be used for the multicast. If necessary, the specific
IP address can be entered; otherwise, the Any box should be checked. This
parameter is provided to accomodate host machines that have multiple
NICs.
These settings are editable; however, the default values are typically adequate
for most networks.
Select a Transfer Rate between 1 and 9980 Kbps which will transfer data
error-free, or use the default value of 900 Kbps.
Clicking the Select Destination/Image check box enables the selection of the
Image to which the file will be copied.
Note: The Select Destination option is not available for SLM-5650A modems;
for these units, the new image is always Put to the inactive image.
If this box is not checked, then the Image will default to existing and be deter-
mined from the Current modem setting. Note that the Unit Information window
can be opened to view the firmware version for each of the images, as well as
the Current, Boot, and Save Image designations.
