中文资料：
为了提供对恶意数据包故障的容忍度，A-B 81001-956-63-R可以作为两个恶意主机之一运行。当数据包从一个节点传递到另一个节点时，流氓主机会更改每个数据包。当数据包第二次返回到流氓主机时，流氓主机识别出它是一个流氓数据包，并将其从环中移除。当检测到流氓数据包时，会在本地中断状态寄存器（LISR）中设置流氓数据包故障标志。流氓分组故障位的断言可以可选地断言VMEbus中断，以通知主机该条件存在。
盗贼大师0和盗贼大师1被提供来相互交叉检查。Rogue Master 0启用从E5引脚3和4移除跳线分流器。Rogue Master 1通过从E5引脚5和6移除跳线分流器来启用。请参阅“A-B 81001-956-63-R用户可配置开关和跳线的位置
注意：网络中的两个板不应设置为同一个流氓主机。否则，两者中的一个将错误地删除另一个发起的数据包
英文资料：
To provide tolerance to rogue packet faults, the A-B 81001-956-63-R can operate as one of two rogue masters. A rogue master alters each packet as it passes from one node to another. When the packet returns to the rogue master a second time, the rogue master recognizes that it is a rogue packet and removes it from the ring. When a rogue packet is detected, a rogue packet fault flag is set in the Local Interrupt Status Register (LISR). The assertion of the rogue packet fault bit may optionally assert a VMEbus interrupt to inform the host that the condition exists.
Rogue Master 0 and Rogue Master 1, are provided to cross check each other. Rogue Master 0 is enable removing the jumper shunt from E5 pins 3 and 4. Rogue Master 1 is enable by removing the jumper shunt from E5 pins 5 and 6. See “A-B 81001-956-63-R Location of User Configurable Switches and Jumpers
NOTE: Two boards in the network should not be set as the same rogue master. Otherwise, one of the two will erroneously remove packets originated by the other
