BK9053-倍福耦合器说明书(中文版)(10)

Connection via a switch经由开关连接

Connect the PC's network card to the hub using a standard Ethernet cable, and connect the hub, again using a standard Ethernet cable, to the Bus Terminal controller. Connection via a switch is done in the same way.

PC的网卡连接到使用标准以太网电缆的枢纽，连接枢纽，使用标准以太网电缆再次，总站控制器。经由开关连接被以相同的方式完成的。

Direct connection between PC with Ethernet card and BK910x

BK9053

Because the BK9053 owns only one port the set up has to be done in classic star topology. 因为BK9053只拥有一个端口的设置，必须在经典星形拓扑做

BK9103

The BK9103 features an internal triple switch with two external ports and one internal port. The internal switch facilitates creation of a line topology. A maximum of 20 BK9103s can be connected in series in a physical line. The maximum distance between two BK9103s is 100 meters. The maximum overall line length is therefore 2 kilometers. No further switch may be included in this line.

该BK9103具有内部的三重开关，两个外部端口和一个内部端口。内部开关可用于创建线型拓扑结构中。最多20 BK9103s可以串联连接在一条物理线路。 2 BK9103s之间的最大距离为100米。因此，最大总线路长度为2公里。没有进一步的开关可以被包括在该行。
