Increasing Data Signal Integrity
You can increase data signal integrity by installing a 120
ohm termination resistor on either the Touchscreen Sensor or
the Pioneer Gold Controller’s main board. The Pioneer Gold
Controller and Touchscreen Sensor both have the resistor
installed before they are shipped.
On the Touchscreen Sensor, install the resistor between terminals
A- and B+. See Figure 4-20, this page.
On the PG Controller’s main board, install the resistor on
connector “J8” between terminals A- and B+.
