15.SD and MS connectors (10-pin SD, MS)*

These connectors support the sophisticated memory devices called Secure Digital (SD) memory card and Memory Stick (MS). These devices facilitate fast and secure downloading of all types of digital files such as photos, music, news, and movies. You may also use SD and MS to directly record audio, video, and still photos. The SD and MS are non-volatile devices so they do not require power to retain the information stored in them.

*The SD and MS connectors may or may not be mounted depending on SI requirements.

You need an SD/MS reader to use the SD and MS devices. The SD, MS, and the SD/MS reader are optional items and may be purchased separately.
