Figure 3-24 Put Application / Codecast Application dialog
For a Put Application, 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 in the main
window) of the binary file to be Put to the target Vipersat modem.
For a Codecast Application, 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 Applica-
tion 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.
