Appendix E
Startup Data Sequences
The data on the following pages presents the startup data
sequences registered by the TracVision L2. The first section shows
the sequences registered by a system that is connected to an IRD
low-speed data port. The second section shows the sequences
registered by a system that is NOT connected to an IRD low-speed
data port. Both sections show two routines. One is the standard,
full initialization routine; the second is that registered by
TracVision L2 if it is turned on and acquires the satellite via the
“Instant On” operation (described in Section 3, “Using Your
TracVision L2”). These sequences can be recorded using the data
port and a PC.
