CURTIS 1311 HANDHELD PROGRAMMER
The Curtis 1311 handheld programmer provides programming, diagnostic, and test capabilities for the
controller. The power for operating the programmer is supplied by the host controller via a 4-pin Molex
connector.
The programmer includes a 7-line alphanumeric LCD display, rockertype keys for navigating through the
display and for modifying parameters (+/-), and three keys that can be used as bookmarks.
The 1311 programmer is easy to use, with self-explanatory functions. After plugging in the programmer,
wait a few seconds for it to boot up and gather information from the controller.
For experimenting with settings, the programmer can be left plugged in while the vehicle is driven.
