Figure 3-40 Select Base Modem Image / Codecast Select Base Modem Image dialog
Because Codecast utilizes multicast with no verification, the Codecast Select
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.
The default Base Modem Image To Run can be designated by clicking on the
desired Image radio button:
• Image #1 – The base modem will run from the image in the target unit’s
slot with the label of Image #1.
• Image #2 – The base modem will run from the image in the target unit’s
slot with the label of Image #2.
Note that the Unit Information window can be opened to view the firmware
version for each of the images.
Refer to the “Image Selection” section on page 3-15 for additional information.
