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.

(No condensation)

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.

When serial data received from the Temposonics sensor is ready to be output
as parallel data by the SSI-1016J unit, the SSI-1016J sends a Data Ready
Signal to the controller. The parallel output may be read while the Data
Ready Signal is low (output transistor is on). The parallel output is being
updated and may not be read while the Data Ready Signal is high (output
transistor is off).

When using Automatic Mode, the Data Ready Signal depends on the
cycletime setting.
See page 12 for information about Read Command Mode

When the Mode Select / Cycle Time Select Rotary Switch (mounted on
SSI-1016J face) is set to “C”, the SSI-1016J unit switches to Read Command
Mode. The Read Command + Signal looks like Figure 6 below. The
SSI-1016J unit outputs an SSI signal to the Temposonics sensor on the rising
edge of the Read Command Signal.

Tb: >100μs

(output transistor is off), the SSI-1016J parallel output data is being updated.
The parallel output data can be read once the Data Ready Signal returns to
low.

 Use a shielded, twisted-pair cable to connect the SSI-1016J and

Temposonics sensor. A voltage drop in the power supply voltage may
occur due to the impedance of this cable. Check that the supply voltage
at the sensor is within the specifications (+24Vdc, +20%/-15%).

 Check that the use environment is within the SSI-1016J operating

temperature (0℃-70℃). When mounting the SSI-1016J unit in a control
panel near other devices that produce heat, use a fan or other cooling
devices.

 To avoid induced noise and other signal quality issues, place all

connections away from cables carrying heavy currents.
