Start-up Menu Selection by Remote Access Control (RAC) 4.2.4
The RAC functionality is supported by all CORTEX products (CRT, HDR, ACS, …) from SPS Kernel
version 2.7 and MCS kernel version 1.9.
General 4.2.4.1
On some CORTEX products (CORTEX CRT, CORTEX HDR, etc…) a start-up menu offers several
high-level architectures (combination of hardware and software resources) corresponding to different
mission requirements.
When starting up the CORTEX software, menu selection can be done either locally (user interface
described hereafter) or remotely (Remote Access Control) by sending control commands to a specific
RAC data server on the CORTEX machine (RAC port # 3003). Control commands are described in the
Ethernet ICD STI 100013, section 2.6.
Starting a new menu while the CORTEX is running takes only a few seconds (2 seconds best case, up
to 20 seconds when a new FPGA software needs to be downloaded from the hard disk to the target
FPGA).
