The hardware for the data sources to be used in the ATLAS trigger demonstrator program has been designed and built. As a basic element, the SLATE2 module has been used. The S-LINK protocol, as a transferring data standard, has been chosen. A cheap implementation of the S-LINK, the Parallel Electrical S-LINK, has been built. Featuring all the specification laid down in the standard it uses a parallel twisted pair copper cable as a physical layer. A standard SCSI cable has been used. Both the Source and Destination Cards have the same PCB layout. The link may receive 32-bit wide data words at max 40 MHz input rate. Running with 40 MHz link clock, it outputs 32-bit data at a rate of 20 MHz, giving a total a bandwidth of 80 MB/s. The authors report on main characteristics of these implementations. The SLATE2SLINK cad has been built to interface the SLATE motherboard to the S-LINK environment. This daughter card is capable to house and independently control 3 S-LINK sites. Running with the 25 MHz SLATE`s clock and 32-bit data, it features a total bandwidth up to 300 MB/s.
