Note 1
: These signals are on a cluster of 6 miniature coacial connectors on the rear panel of the MSP module
Note 2
: These signals are on a multiwire ribbon cable connected to the IONUM board located on a panel above the computer I/O connectors. Direct connection to the Samtec
multipin connector is not recommended.
Note 3
: These signals are on a cluster of 10 miniature coacial connectors on the rear panel of the MSP module. For Cortex CRT applications, only 5 of the 10 connectors are
used.
Note 4
: signal level can be adjusted from registry keys. See section 4.2.8.9.4
