ABB 5SHY3545L0016 3BHB019719R0101可控硅模块可使用图10-20或图10-21为这些底板定制Y形电缆。图10-21显示了标准（工厂制造）Y形电缆的制造方法。通过移除为早期版本的远程底板定制的Y形电缆中的引脚1，引脚7（0V）信号参考源于主（CPU）基板。在这些早期版本的远程底板中，引脚1连接到引脚7（0V），并且还AC耦合到远程机架接地。当将这些底板与100%屏蔽的Y形电缆结合使用时，引脚7（0V）参考将通过Dsubminiature连接器外壳不正确地直流耦合到远程机架接地，该外壳直流耦合到远端机架接地。在远程底板ABB 5SHY3545L0016 3BHB019719R0101（及更高版本）和ABB 5SHY3545L0016 3BHB019719R0101（及更低版本）中，引脚1屏蔽信号直流耦合到远程机架接地，而不连接到引脚7（0V）。这通过提供良好的连续电缆屏蔽实现了最佳的抗干扰性，并且仍然允许引脚7（0V）信号参考源于CPU基板，而无需移除任何工厂或定制电缆中的引脚1。D超小型连接器外壳仍然与远程机架接地直流耦合。ABB 5SHY3545L0016 3BHB019719R0101

Custom built Wye cables for these baseplates can be made using either Figure 10-20 or Figure 10- 21. Figure 10-21 shows how the standard (factory made) Wye cables are made. By removing pin 1 in custom built Wye cables made for the earlier versions of remote baseplates, the pin 7 (0V) signal reference originates in the main (CPU) baseplate. In these earlier versions of the remote baseplates, ABB 5SHY3545L0016 3BHB019719R0101pin 1 was tied to pin 7 (0V) and also AC coupled to the remote frame ground. When using these baseplates in combination with the 100% shielded Wye cables, the pin 7 (0V) reference would be improperly DC coupled to the remote frame ground through the Dsubminiature connector shell, which is DC coupled to the remote frame ground. In the remote baseplateABB 5SHY3545L0016 3BHB019719R0101(and later) andABB 5SHY3545L0016 3BHB019719R0101 (and later), the pin 1 shield signal is DC coupled to the remote frame ground and not attached to pin 7 (0V). This allows the best noise immunity by providing a good continuous cable shield, and still allows the pin 7 (0V) signal reference to originate in the CPU baseplate without the need for removing pin 1 in any factory or custom built cable. The D-subminiature connector shell is still DC coupled to the remote frame ground.
