Record in Black Box Mode
In black box mode, the Spider executes the run schedule in which the start
recording and stop recording entries associate with recording function. The start
recording entry activates the recording sequence, and the stop recording entry
stops the recording sequence.
When the start recording entry is executed, if the recording is in progress, the run
schedule entry will jump to the next entry immediately; if the recording status is
idle, it starts a new recording sequence.
When the stop recording entry is executed, if the recording is in progress, it stops
the current recording sequence; if the recording status is idle, the run schedule
entry will jump to the next entry immediately.
Except the start recording and stop recording entries, the run schedule doesn’t
affect the recording setup under the Test Configuration.
Refer to the black box mode chapter in this manual for more information about
the black box configuration.
Record to Spider-NAS
Spider-NAS (Network Attached Storage) is a dedicated storage device that works
with front-end modules from Crystal Instruments, including the Spider-80x and
Spider-81/81B. The Spider-NAS is connected to each Spider data acquisition
module through eight high-speed data bus ports, and an Ethernet port is used to
configure and control the system from any location on the network.
For the hardware including hardware settings, details are introduced in the
Spider-NAS Manual.
Although EDM supports up to 24 Spider modules with 192 input channels,
recording to NAS has certain limitation when highest sampling rate of 102.4 kHz
is selected. At the sampling rate of 102.4 kHz, the recording to NAS is limited up
to 168 channels (7 channels * 24 modules). At sampling rate of 81.92 kHz or
lower, the recording to NAS can apply to 192 channels at maximum.
In EDM, Record to Spider-NAS function can be found under Global Settings-
>Working Folder as shown below. Once the Record to Spider-NAS is selected, all
the recorded data files will be saved to Spider-NAS system by default.
