Introduction

1.6Resistor Jumpers

Figure 3 shows the location of the zero (0) ohm resistor configuration jumpers. They control the clock configuration and the clamping voltage. To alter the factory configuration of the DE1B55503, the jumpers must be soldered on or off the DE1B55503 board. See Appendix A, “Signal and Default Information”.
