C.2. LIST OF UPLINK COMMANDS

C.2 List of Uplink Commands

All commands are issued in the form

COMMAND “space” ARGUMENT 1 “space” ARGUMENT 2 ... “CR”.

Commands requiring numeric arguments must be zero padded. For example,

to request record number eight, the command:

get record 08

must be issued, rather than get record 8. Table C.2 shows the complete lis t

of accepted commands and the arguments that they require.

C.3 PCB Design

Figure C.1 shows the top solder side and Figure C.2 shows the bottom solder

side. Figure C.3 shows a reduced circuit schematic. The full-size schematic

is available on the attached CD in A3 size. Figure C.4 shows the partially-

populated prototype board used throughout this project for evaluation.
