Power and Ground
Q20
: Are there any warning signs that indicate poor grounding practices have been used
A20
: If errors occur which do not appear to be due to software or to the external communications link, then loop
the T7121 data path back at the concentration highway. Any data transmitted should be received error-free. If
there are errors, poor grounding might be the cause. Look for glitches on RESET and WR leads. Connect
RESET to ground and do a software reset; if the error rate improves, RESET is being glitched and improved
grounding should help.
