Transmission of Command
Transmits a command to the OBR. Only one command should be specified in each command
transmission session. Various options including "Readout mode", "Data transfer format", etc., can
be specified for this transmission. These setup specifications, if written to EEPROM, do not have to
be set each time the power is on.
For information about the setup procedure refer to "Setting Operation Mode".
