在下一代RS-485总线的概念下，BOSIKA将原本用于延长RS-485通信距离并且提高负载能力的中继器与RS-232/RS-485转换器进行绑定，推出RS-232/RS-485中继转换器，同时对RS-485信号的流向进行整理，使得用户在使用时感觉就是一个RS-232与RS-485的转换器。这种思想体现在最新的《一种带中继功能的串口转换器》专利文献中。对于BOSIKA而言，下一代RS-485总线的变化就是要不受最远距离和节点数的限制，同时下一代RS-232/RS-485中继转换器485A2还得保持无需供电的特性。

在这个思路中，BOSIKA的RS-232/RS-485中继转换器突破了传统RS-485总线的节点数和距离的限制。每接一个RS-232/RS-485中继转换器，RS-485信号都得到了中继增强，所以这种RS-485总线不再受一条RS-485总线最远1200米的限制，而是当接M个转换器时就可以达到1200米的M倍距离，M是否不受限制---本文将讨论M的理论极限。传统的RS-485总线有接负载个数的限制，比如128个，就是同一条RS-485总线中最多挂128个RS-485口。使用M个RS-232/RS-485转换器构成的RS-485总线中，由于接入的转换器将RS-485总线分开为了M段（每一段之间相当于有一个中继器），所以当接M个转换器时就可以达到128×M倍的负载个数，M是否受负载数限制---本文也将讨论。
