S-CAB is DCC compatible
S-CAB requires a radio link between an S-CAB throttle and a radio receiver connected to a DCC-compliant decoder in a locomotive. In order for S-CAB to be DCC compatible, the message from the receiver must be identical to the format defined by NMRA S-9.2 DCC Communications Standard.
Anyone wanting to build an S-CAB receiver can buy the radio receiver from Linx Technologies or one of their distributors. There's nothing to prevent decoder manufacturers adding the radio receiver to their product.
The Product page lists several popular decoders that are already integrated with radio and ready for operation with S-CAB.
What is DCC?
Digital Command Control (DCC) transmits digital commands to locomotives through the track and is defined by two fundamental standards prepared by the National Model Railroading Association (NMRA).
S-9.1 DCC Electrical Standard (2004). This standard defines how information is encoded to communicate using track power supply. Encoding is the only part of this standard applicable to S-CAB.
S-9.2 DCC Communications Standard (2004): This standard covers the format of messages sent to Digital Decoders.
