3.2.2 Internal SD Card Installation
The Janus controller uses a Secure Data (SD) card for storage of configuration data, executable program,
application program source files, and user data files. A high capacity SDHC card is pre-installed on all units shipped
from the factory. Contact CTI support if the SD card is missing. Because all configuration and operational files are
contained on the SD card, the complete controller profile can be transferred to another unit simply by swapping
SD cards.
The receptacle for the internal SD card is located on the controller circuit board as shown in the following pictures.
