DACs cleared to uncalibrated zero-scale: 0 V, ±50 mV unless the alarm

function is enabled for the output (Note 3)

Alarm functionality

Either or both outputs may be configured to go to defined values when

an Ethernet connection with a host is established or lost.

Output update rate

1000 to 5000 S/s typ, on local network (Note 4)

Slew rate

5 V/µs

Throughput

Software paced

1000 to 5000 S/s typ, on local network (Note 4)

Note 2: Leave unused AOUTx output channels disconnected.

Note 3: AOUTx defaults to 0 V whenever the device is powered on or a reset command is issued to the device,

unless the alarm functionality is enabled for the output.

Note 4: This is the typical throughput when the device and host are both connected by Ethernet to the same

local network. The throughput can vary significantly, and typical throughput is not guaranteed if a

wireless connection is involved or data is sent over the internet.
