Installation
Jumper Settings
The Model 69460-001 Card contains three jumpers (P5, P6, P7). These jumpers set the logic levels of the
card's input control lines to either active HIGH (24 V) or active LOW (0.7 V). For operation in a
standard Central Page system using the Model 10961-001 Interface Panel or Model 10460-002 Interface
Panel, the jumpers must be set to active HIGH. Active HIGH is the factory default setting for all jumpers.
The active LOW setting is used only in special applications in which a custom-designed interface panel is
present or the card is being controlled by a device other than the interface panel. Refer to Figure 1.
