The SSI-1016J unit converts serial SSI data output by Temposonics sensors
to parallel data. SSI (Synchronous Serial Interface) is a serial
communication protocol developed and widely used in Europe. By
converting the SSI signal to a parallel signal with the SSI-1016J,
Temposonics sensors can be used with a wider variety of controllers.
Furthermore, the SSI-1016J provides the necessary clock signal for SSI
communication.

The SSI protocol is a serial transmission over a 4-wire, RS422-compliant
wiring configuration. A clock pulse train from a controller is used to gate
out sensor data. One bit of position data is transmitted to the controller for
each clock pulse received by the sensor. The maximum SSI clock baud rate

required between each clock pulse train.

The output data is formatted in either binary or gray code with either 24, 25,
or 26 bits of data depending on Temposonics sensor settings. The most
significant bit (MSB) comes first and the least significant bit (LSB)
represents the resolution specified by sensor specifications. Each bit is
transmitted synchronously with the rising edge of each clock pulse.

The SSI-1016J unit interfaces with 24, 25, and 26 bit SSI Temposonics
sensors with no adjustment necessary and outputs parallel data via an open
collector output. The SSI-1016J has two operation modes which are
selectable via the rotary switch mounted on the SSI-1016 front panel.

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.
Automatic mode constitutes steps 2→3→4 shown in Figure 1 above.

※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.
Read command mode constitutes steps 1→2→3→4 shown in Figure 1
above.
