SF-2110 User Guide – Rev. A 

Chapter 2 ................................. Interfacing 

This chapter details the SF-2110 GPS sensor 
connectors, LED display, appropriate sources of 
electrical power, and how to interface the 
communication ports. 

Electrical Power  

A rear panel 9-pin Positronic male connector provides 
electrical power to the SF-2110. Pin assignments are 
given in Table 2; see Figure 4 for pin location on the 
connector.
