A)
Automatic Mode
When set to automatic mode the SSI-1016J unit supplies a clock signal
based at a set interval (cycle time). This cycle time can be selected via
the rotary switch on the SSI-1016J front panel. Upon receiving this
clock signal the Temposonics sensor outputs its measurement data as
described above. This data is received by the SSI-1016J unit and
immediately output to the controller as parallel output.

※
In automatic mode the Data Ready Signal is used to communicate the
timing for reading out the parallel output. See page 11 for details.
B)
Read Command Mode
When set to read command mode the SSI-1016J unit waits for a read
command from the controller. Once the read command is received, the
SSI-1016J unit supplies a single SSI clock signal to the Temposonics
sensor, which returns a single SSI data output. The SSI-1016J is
immediately output to the controller as parallel output.
