The total system spans up to 239 networks, including remote I/O networks. In MELSECNET/10 mode, the maximum number of groups per network is 9; in MELSECNET/H mode, it's 32. ## Cabling and connectors The QJ71BR11 uses a coaxial cable obtained by the user — typically 3C-2V, 5C-2V, or 5C-FB. The user provides the connector plug for the chosen cable. The transmission path is a single bus topology.","metaTitle":"Mitsubishi QJ71BR11 MELSECNET/10 Coaxial Bus Module, 10 Mbps","metaDescription":"Mitsubishi QJ71BR11 data link unit for Q Series.
