RS4 Data Streamer
This fast fact sheet provides basic reference information for the RS4
Data Streamer and related devices. See reverse for Synapse set-up.
See the System 3 Manual for more detailed device information.
Fast Facts
Overview. The RS4 stores data streamed directly
from the RZ2, through a special optical DSP. Access to
the RS4 storage array is provided through a network
connection, direct connection to a PC, or data transfer
to a USB storage device.
Hardware Setup. An RZ2 provides one streaming input
to the RS4. Additional RZ2 devices can be connected to
the same RS4 provided it has available streaming ports
(B, C, or D). The fiber optic cables are color coded to
prevent wiring errors.
RS4 to RZ Connection Diagram
In the diagram above, a single RZ connects to the RS4.
Network Setup. The RS4 can be accessed directly via a
PC or across a local area network (LAN). In either case
connect the corresponding Ethernet cable to the RS4
port labeled Network.
RS4 PC and Network Connection Diagram
Possible connections to a PC (1) or LAN (2).
The default IP address is 10.1.0.42.
To access the RS4 through a PC you must configure
the PC TCP/IP settings and set the PC IP address to
10.1.0.x, where x is any value, 1 - 254 except 42.
To access the RS4 file system through a LAN, DHCP
must be enabled on the network.

Network LED lit - traffic is present and

Powering On. Always power the RS4
down during an Idle state. Idle status can
be checked in the Ports tab. Failure to
power down during Idle status may result
in the RS4 performing a file system
check during the next boot process and
possible data loss.

Important! When data is no longer streaming to the
port or if streaming has been paused for longer than 1
second, the session is concluded (data files are closed)
and a new session will begin when a new data stream is
presented.
For more information on the user interface, see the RS4
Data Streamer section of the System 3 Manual.
File Space Management. Data sets containing a large
number of channels, or long recording periods may take
longer to display and process on the RS4 and will also
lengthen the amount of time for file system checks. TDT
recommends removing data from the RS4 that is no
longer needed.
The Touch Screen Interface. The four tabs on the RS4
LCD touch screen display status information and can be
used to configure RS4 options.
Ports. View information for storage array streams,
local storage rates, and storage size.
Storage. Select and review a list of stored data files.
Items may be deleted or moved and copied to a USB
device. USB Storage device status information may
also be displayed.
Status. View device IP address and other system
information.
Config. Reformat storage array or update firmware.
Two RAID based array types are supported, Striped
and Mirrored. The default array type is Mirrored, which
provides redundant data back-up in case of drive
failure.
Updating the Firmware. The RS4 firmware can be
updated on the Config tab. Firmware is downloaded
from the TDT server and automatically installed on the
RS4. Connection to a DHCP enabled network that has
internet connectivity is required to retrieve any updates.
Device Address. The path \\RS4-#XXXX\data is used
to access the RS4 storage array, where #is the total
number of streaming ports on the RS4 back panel and
XXXX is the device serial number. data is the folder
containing the data saved to the storage array.
The device address is also shown on the top of the
Ports tab. Alternatively, you can access the RS4 by its IP
address, which is shown on the Status tab.
Synapse Configuration. The RS4 must be
configured in the Rig Editor.
Click the icon in the
tree to display con-
figuration options.
Select Broadcast
or Direct connec-
tion, then enter the
IP address.
Alternatively, click
the Check Network
button and select
the RS4 IP address
in the Host Address
drop-down menu.
The DSPS optical DSP should be auto-
detected. Click the check box next to the RS4
icon to enable the streamer.
Data Transfer Rate. The maximum data rate for each
RS4 streaming port is 12.5 MB/s. This equates to
streaming 256 16-bit channels at a sampling rate of
~25 kHz per streaming port. With four ports available,
up to 1024 channels can be streamed to the RS4 at this
rate.
When using the PZ5 at 25 kHz or below, you must use
the Float (32 bits) data format. If you are recording 128
channels at 50 kHz, you must AC couple the PZ5 and use
the Short (16 bits) data format.
