Installation
Display Jumpers and Terminals
The default jumper positions are shown in Table 1. The
hardware configuration of the Informer display can be
customized by changing jumper positions and wiring
the terminals for the desired configuration.
Jumpers
Jumpers JP1, JP2, and JP3 are 3-pin connectors with
2-pin shunt connectors installed. The pins are num-
bered 1, 2, and 3. See Fig. 5.
JP1
Jumper JP1 determines the meter pulse source. When
pins 1 and 2 are jumpered together, the Informer
display is configured to receive pulses from an external
meter, which must be connected to terminals 3 and 4
on connector J2. When pins 2 and 3 are jumpered
together (the default position for Model 288665), the
Informer display is configured to accept pulses from
the meter it is mounted on. This position minimizes
power consumption for battery operated configura-
tions.
JP2
Jumper JP2 determines the source of power for the
Informer display. When pins 1 and 2 are jumpered
together, the Informer display is configured to receive
power from an external DC power source, which must
be connected to terminals 1 and 2 on connector J1.
When pins 2 and 3 are jumpered together (the default
position for Model 288665), the Informer display is
configured to receive power from the internal 9 Volt
battery.
JP3
This jumper is not used. It should be removed or left
on pins 2 and 3.
