Sdl4 Operation - B&R PC 3100 User Manual

4.1.1.3 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 is used for the device con-
nection, which is ideal for confined spaces in feed-throughs and swing arm systems.
4.1.1.3.1 SDL4 operation with SDL4 transmitter
In SDL4 operation with an SDL4 transmitter in the B&R industrial PC, all communication between the Automation
Panel and B&R industrial PC takes place via a single SDL4 cable.
In addition to the display data, information from the touch screen, matrix keys, LEDs and service/diagnostic data
is transferred. The Automation Panel can be installed up to 100 m away from the B&R industrial PC. USB 2.0 is
also transferred over this distance and fully integrated into SDL4. External adapter modules are not required.
The brightness of the display can be set via the ADI Control Center, for example.
Availability of the interfaces on the Automation Panel with SDL4 receiver:
✓
SDL4 interface USB1, USB2
Maximum cable length for SDL4: 100 m
Requirements
• Automation Panel with SDL4 receiver
• B&R industrial PC with SDL4 interface
• SDL3/SDL4 cable
4.1.1.3.2 General limitations
• USB 2.0 transfer is limited to 150 Mbit/s with SDL4.
• A display is always emulated by the SDL4 transmitter using EDID data and hot plug detection, so DVI-
compatible operation is possible. For this reason, the following behavior may occur during operation with
multiple displays.
In the operating system, a connected panel is reported by the video driver even in the following situations:
° No SDL3/SDL4 cable is connected.
° There is no connection established yet between the SDL4 link module and SDL4 transmitter.
This behavior can be avoided by appropriate configuration in BIOS or via the graphics driver.
