DESCRIPTION
This will short out R7, R13 and R19 respectively. The effect is to disable the phase
compensation filter on the analog inputs IAN, IBN and ICN respectively. Default
Closed.
This will connect the analog input IAP, IBP and ICP respectively to ground. Default
Open.
This will connect the analog input IAN, IBN and ICN respectively to ground. Default
Open.
This will short out R9, R15 and R21 respectively. The effect is to disable the phase
compensation filter (for Current transformers) on the analog inputs IAN, IBN and ICN
respectively. Default Closed.
This will short out R10, R16 and R22 respectively. The effect is to disable the anti-alias
filter on the analog inputs IAP, IBP and ICP respectively. Default Open.
Enable the anti-alias filter on IAP, IBP and ICP respectively.
This will short out R8, R14 and R20 respectively. The effect is to disable the anti-alias
filter on the analog inputs IAN, IBN and ICN respectively. Default Open.
Enable the anti-alias filter on IAN, IBN and ICN respectively.
This will connect the Analog and Digital ground planes of the PCB. Default Closed.
This will connect an external reference 2.5V (AD780) to the ADE7754/8
This will enable the ADE7758 on-chip reference.
This connects the DVDD and +5V (buffers) supply for the evaluation board together.
Default Closed.
This connects the AVDD and DVDD supply for the evaluation board together. Default
Closed.
This will short the attenuation network on the voltage channels. Default Open
This will connect the optical isolator ground to the evaluation board ground (DGND). If
full isolation between the evaluation board and PC is required, this jumper should be left
open
This will short out R40. The effect is to disable the anti-alias filter on the analog input
VN. Default Open
This will connect the analog input VN to ground. Default Closed.
This will connect the analog inputs VCP, VBP and VAP to ground respectively. Default
Open-
This will short out disconnect Analog input VCP, VBP and VAP respectively from the
ADE7758. Default Closed
This connects the buffered logic output VARCF to the LED CR1. Default Open.
This connects the buffered logic output VARCF to BNC J1 connector via an optical
isolator. Default Open.
This will short out disconnect Analog input VN from the ADE7758. Default Closed
This connects the buffered logic output CF to BNC J3 connector via an optical isolator.
This connects the buffered logic output CF to the LED CR2.
This connects the buffered logic output IRQ to the parallel port.
This connects the uffered logic output IRQ the LED CR3.
This jumper is not used for the ADE7758, the setting does not matter.
