2.1.3 SDL4 operation
Smart Display Link 4 (SDL4) technology transfers all communication channels between a B&R industrial PC and
panel up to 100 m over a standard Ethernet cable (min. Cat 6a). An RJ45 connector ideal for narrow spaces such
as feed-throughs and swing arm system is used to connect to the device.
2.1.3.1 SDL4 operation with SDL4 transmitter
In the SDL4 operating mode with an SDL4 transmitter in the B&R industrial PC, all communication between the
Automation Panel and B&R industrial PC is handled using a single SDL4 cable.
In addition to display data, information from the touch screen and matrix keys as well as service and diagnostic
data is transferred. The Automation Panel can be installed up to 100 m from the B&R industrial PC. USB 2.0 is
also transferred over this distance and fully integrated in SDL4. External modules are not necessary for this.
The brightness of the display can be set using the ADI Control Center, for example.

2.1.3.2 General limitations
•
The USB 2.0 transfer rate is limited to 150 Mbit/s with SDL4.
•
The SDL4 transmitter constantly emulates a display using EDID data and hot plugging code; this allows
DVI-compatible operation. As a result, improperly displayed images are possible during operation with
multiple displays. In Windows, a connected panel is registered by the graphics driver even in the following
situations:
°
No cable is connected.
°
A connection has not yet been established between the SDL4 link module and SDL4 transmitter.
These improperly displayed images can be circumvented by making suitable configurations in BIOS or via
the graphics driver.
