PRELIMINARY TECHNICAL DATA
JUMPER SETTINGS
DESCRIPTION
This will short out R50. The effect is to disable the anti-alias filter on the
analog input V1P. Default Open.
Enable the anti-alias filter on V1P.
This will connect the analog input V1P to ground. Default Open.
This will short out R51. The effect is to disable the anti-alias filter on the
analog input V1N. Default Open.
Enabe the anti-alias filter on V1N.
This will connect the analog input V1N to ground. Default Open.
This connects the buffered logic output IRQ to the LED1.
This connects the buffered logic output IRQ to pin 10 on the D-Sub connector
via an optical isolator.
This connects the buffered logic output SAG to the LED2.
This connects the buffered logic output SAG to pin 11 on the D-Sub connector
via an optical isolator.
This will short the attenuation network on Channel 2. Default open.
This will connect the analog input V2P to ground. Default Open.
This will short out R57. The effect is to disable the anti-alias filter on the
analog input V2N. Default Open.
Enable the anti-alias filter on V2N.
This will connect the analog input V2N to ground. Default Open.
This will connect the Analog and Digital ground planes of the PCB. Default
Closed.
This connects the buffered logic output CF to the LED4.
This connects the buffered logic output CF to BNC2 connector via an optical
isolator.
This will connect an external reference 2.5V (AD780) to the ADE7756.
This will enable the ADE7756 on-chip reference.
This will connect the optical isolator ground to the evaluation board gound
(DGND). If full isolation between the evaluation board and PC is required,
this jumper should be left open.
This will short out R41. The effect is to disable the phase compensation filter
(for shunts) on the analog input V1P. Default Closed.
This connects the buffered logic output ZX to the LED3.
This connects the buffered logic output ZX to pin 12 on the D-Sub connector
via an optical isolator.
This connects the AVDD and DVDD supply for the evaluation board together.
Default Closed.
This connects the DVDD and +5V (buffers) supply for the evaluation board
together. Default Closed.
This will short out R42. The effect is to disable the phase compensation filter
(for shunts) on the analog input V1N. Default Closed.
This will short out disconnect Analog input V2P from the ADE7756. Default
Closed.
