SLM-5650 Satellite Modem Revision 2
Front Panel Operation MN/SLM5650.IOM
4–13
Select: CONFIG: Receive: DataRate
The user can enter the desired data rate using step 1 or step 2 as follows:
1. Use the number keypad and enter the desired data rate (see Chapter 3).
2. Use
the
efbc
arrow keys to scroll up and down to select the desired data
rate or symbol rate. When scrolling data rate the symbol rate will be
automatically recalculated and displayed.
IMPORTANT
When entering the data rate, the following interactions need to be taken
into account. If the modulation type selected is 8-PSK or 16-QAM the
minimum data rate allowed is 256 kbps. When changing certain
parameters like modem type, the data rate will default to 64 kbps or 256
kbps. The calculated symbol rate is displayed for the user. This is
helpful for determining the occupied bandwidth required for the
selected modulation type, code rate and overhead.
Select: CONFIG: Receive: Overhead
Select the desired Overhead, Rate, RS-CW, and Depth and then press [E].
Overhead (IESS-308, IESS-309 are standard), (AUPC is optional)
Rate 96 kbps (IESS-308), 1/15 (IESS-309 or AUPC), N/A (none)
