Test points are small metallic pins on the processor module circuit board.
Hardware troubleshooting and testing for proper wiring can begin by
testing for proper voltage or signals at these pins. Test points are labeled
with the letters TP followed by a number. Use Figure 3A.22 to find the
location and function of each test point on the 9/230 Analog CNC. Use
Figure 3A.23 to find the location and function of each test point on the
9/230 Digital CNC.
