The EX1200-7100 carrier provides six lines of control for external microwave switches. Using a pass
through adapter (VTI P/N: 70-0146-026), external microwave switches can be connected to the three 14-
pin connectors located inside the carrier. The signals for the connector pins are shown in Table 4-2.

Although soft front panel (SFP) operation is detailed in the EX1200 Series User’s Manual, the EX1200-
7100 has a unique input/output interface that is available when a pass through adapter is used. When the
SFP is initially viewed, a PIOx_y (PIO1_2 in Figure 4-5) the slot is viewed. From here, the user can enter
the value that will be input or output by the relay driver. When PIO1_2 is clicked, the slot expands to show
the seven bits that are controlled when the input/output is set.
