The connector versions of SF910i (third suffix = Q or QC) come with quick-release
connector. The user do not need to open the SF910i enclosure for making connections.
Plug the connector cable (or pigtail) into the SF910i connector and the user is ready for
next step. The user must need to identify the pin-out in the socket available on the SF910i
or in order to solder the external cable conductors in the connector plug, refer to the
below figure and table. The pin-out in the below figure is as view from the outside of the
SF810i, where the plug inserts into the socket.
Refer to Appendix F and Appendix A to properly select the external cable.
