Functions Transmission medium Mechanical design Konnex TP1 Bus cable selection Screened bus cable 2/10 The Konnex bus serves as a transmission medium: • To commission and remote control the Synco 700 controllers and the Synco RXB room controllers by means of the service tool OCI700.1 • To exchange process data between the Synco devices The simplest form of the "Konnex TP1" bus comprises a two-core bus cable with stranded lines CE+ (red) and CE– (black). CE+ CE− CE+ Red line CE+ Black line W Protective layer W Select the bus cable according to the country-specific offerings by adhering to the values indicated in the "Technical data" section. Bus cables available in EIB market countries as per the specifications are: • YCYM 2x2x0.8 Fixed installation EIB specification Dry, humid, wet rooms Outdoors (not exposed to sunlight) Surface mounted, flush mounted, in pipes • J-Y(St)Y 2x2x0.8 Fixed installation EIB specification Indoors only Surface mounted, in pipes • JH(St)H2x2x0.8 Halogen-free conductor, laid separately • A-2Y(L)2Y or A-2YF(L)2Y Underground cable for remote transmission, outdoors Synco or the Konnex bus allows for bus cables without screening. The screens available for EIB bus cables normally do not need to be connected. If you use a screened bus cable due to expected noise, connect the screen by following standard installation rules.

Engineering notes Network structure Bus topologies Note Network address Notes The Konnex bus is based on a network structure derived from the "European Installation Bus", EIB. A full Konnex network consists of three structural levels. The topmost level is the backbone line featuring 15 main lines (medium level), each of has another 15 lines (bottom level). The three-level network structure requires area or line couplers. Without these couplers, the network structure is limited to one single line. Permissible bus topologies at every level are: Tree, line, and star topologies. These topologies can be mixed as needed. However, ring topologies are not allowed. The tree topology is advantageous if a large network must be created (refer to "Bus topologies" at the end of this document). The term "line" is derived from the EIB environment and refers to the address range of a line (also referred to as subnet in Synco) and not to the bus topology "line". 0.2.003 0.2.254 Konnex TP1 0.2.001 0.2.002 0.2.041 0.2.042 0.2.043 Each bus-capable Synco device (= bus device) in a Konnex network must be assigned a network address. The network address is composed of the area, line, and device address. The address is unique and unambiguously identifies the device location in the total network. The network address in KNX is also referred to as "individual address". • Synco devices having one Konnex interface are bus devices. These are: Synco 700 controllers RMH / RMU, QAW740 room unit, and Synco RXB room controller. • If no area or line couplers are used, the bus devices use the factory-set area / line address 0.2. • If area and line couplers are used and if they are configured accordingly during commissioning, the area and line addresses are assigned automatically to the bus devices.
