***Important Note On Proper Installation Of Circular Connector Cable Ends***
The four circular multi-conductor connectors (A, B, C and D) on the SPI1 are waterproof when the mating cable end
is properly installed. For a waterproof connection, the mating connectors must be fully engaged. Turn the connector
wing nut ¼” past the first feel of resistance, until a definitive click is felt. Failure to fully engage the connector will
result in corrosion of the connector pins as moisture enters the contact areas.
Figure 9 shows the mating connector position at the initial resistance point, and in the fully locked position.

Figure 10 shows a close up view of the GPS antenna connector (E), the communications/datalogger connector (D)
and the power/relay connectors (A,B,C). The SPI1 Stationary Interrupter only has connectors A, D and E
available—the pin outs are identical to SPI1 Portable Interrupter. The pinout of the communications connector (D)
is shown in Table 1. Table 2 shows the pinout of the relay connectors (A, B, C).
