CHAPTER 9: REMOVABLE MEDIA
9.1 Overview
All XL7 OCS models provide a Removable Media slot, labeled Memory Card, which supports standard
MicroSD Flash memory cards. MicroSD cards can be used to save and load applications, to capture
graphics screens and to log data for later retrieval.

9.2 MicroSD Cards
When the MicroSD card format was introduced, it was originally called TransFlash. Cards labeled either
MicroSD or TransFlash, with up to 32 GB of Flash memory, are compatible with the XL7 OCS Memory
slot (larger sizes were not tested at time of publication).
The Memory slot is equipped with a “push-in, push-out” connector and a MicroSD card can be safely
inserted into the Memory slot whether the XL7 OCS power is On or Off.
To install a MicroSD card: Align its 8-pin gold edge connector down, facing the front of the XL7 OCS unit
as shown in Figure 9.2; then carefully push it all the way into the Memory slot. Ensure that it clicks into
place.
To remove the MicroSD card: Push in on the top of the card gently to release the spring. The card pops
out for removal.
9.3 MicroSD File System
The MicroSD Memory slot uses the PC-compatible FAT32 File System. This means that a PC, with a
MicroSD-compatible card reader, can read files that have been written by the XL7 OCS and can write
files that can be read by the XL7 OCS.
However, the XL7 OCS does not support long filenames, but instead implements the 8.3 filename
format. This means that all file and directory names must consist of up to 8 characters, followed by an
optional dot, and an optional extension with up to 3 characters.
Directories and sub-directories can be nested up to 16 levels deep as long as each pathname string does
not exceed 147 characters.
