4.2. Signal Processing Software
CTX Documents
4.2.1.
CTX Documents are configuration files created and managed by the CORTEX SPS.
A CTX Document contains the whole set of configuration parameters that have been previously stored on the
disk under file extension. CTX.
A default CTX Document (cortex-nt.ctx) is loaded by the SPS when the CORTEX is started, and is used to
configure the machine. A copy of this file (CTX Table) is maintained in SRAM and is updated whenever the
CORTEX configuration is changed by the operator. The CTX Table is automatically saved to the CTX Document
on the hard every 10 seconds and at application ending.
Additional CTX Documents reflecting up to ten mission-specific configurations can be created by the operator.
CTX Documents are binary files; they cannot be displayed on the screen or printed out.
SPS Start Sequence
4.2.2.
The default CTX Document loaded by the SPS when the CORTEX is started is C:\Program Files\In-
snec\crtxnt\cortex-nt.ctx. The CORTEX is configured from the contents of this file. This file represents the last
active CTX Document.

STEP 0: Windows boot up sequence.
STEP 1: The Signal Processing Software
(SPS) is automatically started. The CORTEX is
configured from parameters stored in cortex-
nt.ctx file. A copy of the file is maintained in
RAM (CTX Table).
STEP 2: The Monitoring & Control Software
(MCS) (local GUI or remote MCS) opens a
TCP-IP connection to the Monitoring port and
starts monitoring the machine. The CTX Table

is updated when configuration requests are
received on the TCP-IP Control port.
STEP 3: The cortex-nt.ctx file is automatically
refreshed every 10 seconds and at application
ending.
