Description

JP5B

Closed

(default)

Disables the antialiasing filter (composed of R11 and C13) in the IBP signal path.

Open

Enables the antialiasing filter (composed of R11 and C13) in the IBP signal path.

JP6A

Closed

(default)

Disables the antialiasing filter (composed of R10 and C12) in the IAN signal path.

Open

Enables the antialiasing filter (composed of R10 and C12) in the IAN signal path.

JP6B

Closed

(default)

Disables the antialiasing filter (composed of R12 and C14) in the IBN signal path.

Open

Enables the antialiasing filter (composed of R12 and C14) in the IBN signal path.

JP7A

Closed

Connects Pin 1 of the Channel V pin connector (P4) to AGND. Use this configuration in conjunction with JP8A

closed to connect the VP pin of the ADE7953 to AGND via 1 kΩ Resistor R15.

Open

(default)

Pin 1 of the Channel V pin connector (P4) is left floating. Use this configuration in normal operation to drive VP

with analog signal.

JP8A

Closed

Disables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8B is open. Use this

configuration when using a low voltage signal source on the voltage channel.

Open

(default)

Enables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8B is closed. Use this

configuration when using a high voltage signal source on the voltage channel.

JP8B

Closed

(default)

Enables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8A is open. Use this

configuration when using a high voltage signal source on the voltage channel.

Open

Disables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8A is closed. Use this

configuration when using a low voltage signal source on the voltage channel.

JP9A

Closed

(default)

Connects Pin 2 of the Channel V pin connector (P4) to AGND. Use this configuration to connect the VN pin of the

ADE7953 to AGND via 1 kΩ Resistor R16, which should be done when normal single-ended signals are connected

to the ADE7953 voltage channel.

Open

Pin 2 of the Channel V pin connector (P4) is left floating. Use this configuration to drive VN with a differential signal.

JP11

Closed

Connects the ADR280 voltage reference to the REF pin of the ADE7953. Use this configuration when the ADE7953

is configured to use an external reference.

Open

(default)

Disconnects the ADR280 voltage reference from the REF pin of the ADE7953. Use this configuration in normal

operation when the ADE7953 is configured to use the internal reference.

JP13

1, 2

(default)

Connects Pin 1 of the on-board 3.579545 MHz Crystal Y1 to the CLKIN pin of the ADE7953. Use this configuration

when External Crystal Y1 is used as the clock source for the ADE7953.

2, 3

Disconnects Pin 1 of the on-board 3.579545 MHz Crystal Y1 from the CLKIN pin of the ADE7953. Use this configu-

ration when an external clock is used. This clock can be connected to Pin 6 of 16×1 Header P5.

JP15

Closed

(default)

Connects the externally applied 3.3 V power to ADuM1401 Isolator U2. Use this configuration in normal operation

when communicating with the ADE7953 via the interface board.

Open

Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U2. Use this configuration when isolation

and/or communication is not required with the ADE7953.

JP16

Closed

(default)

Connects the externally applied 3.3 V power to ADuM1401 Isolator U3. Use this configuration in normal operation

when communicating with the ADE7953 via the interface board.

Open

Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U3. Use this configuration when isolation

and/or communication is not required with the ADE7953.

JP17

Closed

(default)

Connects the externally applied 3.3 V power to ADuM1401 Isolator U4. Use this configuration in normal operation

when communicating with the ADE7953 via the interface board.

Open

Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U4. Use this configuration when isolation

and/or communication is not required with the ADE7953.

JP18

Closed

(default)

Connects the externally applied 3.3 V power to ADuM1401 Isolator U5. Use this configuration in normal operation

when communicating with the ADE7953 via the interface board.

Open

Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U5. Use this configuration when isolation

and/or communication is not required with the ADE7953.

JP19

Closed

(default)

Connects the externally applied 3.3 V power to the ADuM1250 bidirectional isolator, U6. Use this configuration

Open

Disconnects the externally applied 3.3 V power to the ADuM1250 bidirectional isolator, U6. Use this configuration
