4.2.7.9. Test Points Allocation & Tuning
For High Bandwidth CORTEX configuration, the four sets of TTL test points (Set # 1, 2, 3, 4) can be allocated,
from the following registry keys, to the TMS, TCU and TMUs.
4.2.7.9.1. HBW Telecommand Unit (TCU)
To allocate a set of test points to the TCU.
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\Tcu
Keyword: TPoutSet
Default setting at delivery: 0 (test points disabled)
Set the Byte 0 of keyword in the range 1 to 4 to select test points Set # 1 to Set # 4
Additional settings:
Byte 1 bit 0:
0 for Data Out Updated on Falling edge of Clk Out, Data In sampled on Rising edge of Clk In
1 for Data Out Updated on Rising edge of Clk Out, Data In sampled on Falling edge of Clk In
Byte 1 bit 2:
0 for Data output before the encoders (NRZ-L)
1 for Data output after PCM and convolutional encoders
Byte 1 bit 3:
0 for LVTTL
1 for RS422
4.2.7.9.2. HBW Telemetry Simulator
To allocate a set of test points to a TMS.
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\In-snec\CortexCRT\SetDefault\Preferences\TMSx
(x = TMS number)
Keyword: TPoutSet
Default setting at delivery: 0 (test points disabled)
Set the Byte 0 of keyword in the range 1 to 4 to select test points Set # 1 to Set # 4
Additional settings:
Byte 1 bit 0:
0 for Data Out Updated on Falling edge of Clk Out, Data In sampled on Rising edge of Clk In
1 for Data Out Updated on Rising edge of Clk Out, Data In sampled on Falling edge of Clk In
Byte 1 bit 2:
0 for Data output before the encoders (NRZ-L)
1 for Data output after PCM and convolutional encoders
Byte 1 bit 3:
0 for LVTTL
1 for RS422
