Using the USER 1 and USER 2 BNC Connectors
The USER 1 and USER 2 BNC connectors allow you to use a BNC connector for a digital or timing I/O
signal of your choice. The USER 1 and USER 2 BNC connectors are routed (internal to the BNC-2110)
to the USER 1 and USER 2 spring terminals, as shown in Figure 4.
