Flowcharts; Table 5-5. Board Id Jumper Configuration - Motorola ASTRO Digital XTL 5000 Detailed Service Manual

5-14
The table indicates what the logic levels are, as well as how they correlate to the placement or
removal of a jumper to accomplish the logic level. This is because some of the board ID resistors are
on Pull-Up I/O pins and some are on Pull-Down I/O pins. Therefore, the placement or removal of a
resistor for a Pull-Up I/O is the opposite of what must be done for the placement or removal of a
resistor for a Pull-Down I/O.
Refer to the troubleshooting testpoints chapter for a general idea of where the board ID pins are
located. Refer to the board layout for the exact location with respect to all nearby components before
attempting to place or remove any jumpers.
