18 • Using Linea GigE with the Sapera API Linea GigE Series Camera
Using Linea GigE with the
Sapera API
A Linea GigE camera installation with the Teledyne DALSA Sapera API generally follows the
sequence described below. Detailed installation instructions follow this overview.
Network and Computer Overview
• Linea GigE needs to connect to a computer with a GigE network adapter, either built in on the
the computer motherboard or installed as a third party PCI adapter. See the previous section
Connecting the Linea GigE Camera.
• Laptop computers with built in GigE network adapters may still not be able to stream full
line rates from Linea GigE, especially when on battery power. Thorough testing is required with
any laptop computer to determine the maximum frame rate possible (refer to the Teledyne
DALSA Network Imaging Package user's manual).
• Linea GigE also can connect through a Gigabit Ethernet switch. When using VLAN groups, the
Linea GigE and controlling computer must be in the same group (refer to the Teledyne DALSA
Network Imaging Package user's manual).
• If Linea GigE is to be used in a Sapera development environment, Sapera LT 7.50 needs to
be installed, either before or after the GigE Vision Module software package.
• If using Sapera LT 8.0 or later, all GigE Vision support is automatically installed.
• For maximum sustained data transfers to host, install the Teledyne DALSA GigE Vision Turbo
Drive Technology module even if using Sapera LT 8.0.
• If Linea GigE will be used in a third party GigE Vision Compliant environment, Sapera or
Sapera runtime is not required and you need to follow the installation instructions of the third
party package.
• The Windows Firewall exceptions feature is automatically configured to allow the Sapera GigE
Server to pass through the firewall.
• Computers with VPN software (virtual private network) may need to have the VPN driver
disabled in the NIC properties. This would be required only on the NIC used with the Linea
GigE. Testing by the user is required.
• Once a Linea GigE is connected, look at the small camera icon added to the Windows tray (next
to the clock). Ensure the camera has been found (right click the icon and select Status) Note
that in Windows 7, the icon remains hidden until a camera is connected.
• A new Linea GigE camera may require a firmware update. The File Selector feature is used to
select a firmware file. See the CamExpert procedure "File Access via the CamExpert Tool" on
page 94 for additional information.
• Use CamExpert (installed either with Sapera or Sapera runtime) to test the installation of the
Linea GigE camera. Set the Linea GigE to internal test pattern. See "Internal Test Image
Generator" on page 74.
• Set up the other components of the imaging system such as light sources, camera mounts,
optics, encoders, trigger sources, etc. Test with CamExpert.
