Data Streamers

RS4 Streamer

RS4 Block Diagram

The RS4 is a storage device with a fiber optic connection to an optical DSP on your RZ device. It is likely also connected to the same network as the computer running Synapse.

RS4 Options

RS4 Options

By default, the RS4 uses the RZ device sampling rate. You can set a rate manually by clearing the Sample Rate Max check box to enable the slider. You can also select the data format and any scaling. If streaming from a PZ5 or PZA, due to the large input range and high fidelity, the Float-32 format is recommended. If using a PZ2, Integer-16 format with Scaling set to 1e6 is preferred.

Phantom Store generates header information in the data tank. This is useful if you are reading the RS4 data with TDT applications through the tank server. However, this consumes extra hard disk space on your Synapse computer, so if you are going to read the files directly from the RS4 for your own custom analysis then leave this unchecked.

Send SEV Rename Packets sends a UDP packet containing the tank and block name over the local network to the RS4, so that the RS4 can rename the data files correctly.

When Phantom Store is selected, Send SEV Rename Packets is selected for you.

Important

If you aren't using TDT applications to read the data saved on the RS4, you don't need to select Phantom Store but you absolutely should select Send SEV Rename Packets so that the RS4 data is organized properly.

Use Large Buffer Size allocates more DSP memory to buffer the data before it is transferred to the RS4. This improves reliable when streaming very high bandwidth, high channel count data to multiple RS4 ports. The RS4 should be updated to v1.19 firmware or above to most effectively use this setting.

Monitor Buffer Status adds a runtime interface that warns you of data errors.

Note

See the RS4 section of the System 3 Manual for more information about Data Streamer operations.

PO8e Streamer

PO8e Block Diagram

The PO8e is a data streaming device and requires a multi-channel data source, which you can select from the drop-down menu in the block diagram or drag the PO8e in the Processing Tree and drop it on the source gizmo. You can also choose the range of input channels.
