All Automation Panels are equipped with an insert on the back that allows modular link modules to be connected. Each panel can be adapted to various transfer technologies to match the respective machine topology.

DVI stands for Digital Video Interface. The DVI link is the first choice wherever compatibility with a standard is important. With a DVI connection, the Automation Panel can also be used universally with systems from other manufacturers. With this type of transfer, display data, USB 2.0 data, and touch screen data are sent separately over their own cable.

SDL stands for Smart Display Link. With SDL, all communication between the Automation Panel and APC620 takes place using a single cable. In addition to transferring display data, it also handles touch screen, matrix key, LED, and service data. The Automation Panel can be mounted up to 40 m from the APC620. USB 1.1 is fully integrated in the SDL and transferred over this distance as well. External modules are not needed for this purpose. A panel can be operated on one line with an SDL receiver.

The SDL transceiver makes it possible to connect another Automation Panel to the first Automation Panel. In the second segment, a maximum distance of 40 m can be bridged (the maximum distance is limited by the resolution). To achieve the maximum segment length, cables can be used together with an extender, which acts like an amplifier and is integrated in the cable. Additional hardware is not required.
