This page contains information about the compatible media for LabSat 4 (P).

File Formats

LabSat 4 uses a Linux .ext4 formatted drive for data storage.

Recorded data consists of the following files:

.LS4
The RF signal data is stored in a raw binary file with the extension .LS4.
.ini
The configuration used to record and replay the data is stored in a file with the extension .ini.
.ser
Data from a RS232 log file is stored in files with the extension .ser.
.LS4D
The data from the configured digital channels will be stored in a file with the extension .LS4D.
.txt
Data from a CAN log file is stored in a readable text file.

IMPORTANT

When a scenario is copied to or from the internal SSD in Labsat 4, you must make sure that all the files that are associated with that scenario are copied together.

SD Cards

USB Storage Device

LabSat 4 units have a Host USB port that you can use to connect a USB storage device in .ext4 format.

This is only to be used for copying files to and from the internal SSD.

Solid State Drive (SSD)

Supplied SSD

LabSat 4 includes a Samsung PM893 SSD with 7.68 TB of storage that LabSat 4 will use to replay scenario files from.

The SSD will also include demo files:

SSD Access

The SSD included with your LabSat 4 is removable. To remove or insert the SSD, you must first remove the lid on the LabSat 4 unit. Push down the lid release lever on the rear panel while you push the lid towards the back of the unit. You can then remove the SSD by gently lifting it by the attached tag.

You can reattach the lid to the unit by positioning the locating lugs by the mounting holes with the LabSat logo facing forward. Press the lid down and slide it towards the front of the unit. The lid will automatically lock in place when it is closed correctly.

IMPORTANT

The LabSat 4 unit must be powered down while you remove or re-insert the SSD.

SSD Format

Select the following options to format the SSD via the front panel display on the LabSat 4 unit:

MENU -> File -> Format SDD -> Yes.

IMPORTANT

When you format the SSD all the recorded data on the SSD will be erased.

Network Share

You can also connect to and use Network File Systems (NFS), such as Windows File Explorer and high-speed Network Attached Storage (NAS) devices to manage and replay scenario files.

File Access

You can view and manage the available files on the internal SSD by connecting your LabSat 4 to a PC with an Ethernet cable. Go to the LAN settings on the LabSat 4 display to find the unit's IP address.

Menu -> Setup -> LAN

If required, you can enable and define a static IP address in the LAN settings. Open a file explorer window on your PC and enter \\<IP address> in the address bar.

Note: If Network Security has been enabled on your LabSat 4, you must enter a username and password to access the LabSat4 folder. You can read more about Network Security and how to access the files when it is enabled here.
