Parameter Condition Specification
Output coupling
DC
Power on and
reset state
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.

Parameter Specification
Digital type 5 V TTL input / advanced BiCMOS output
Number of I/O

Configuration
Independently configured for input or output
Pull-up configuration
All pins pulled up to 5 V using 47 K resistors (default).
Can be changed to pull-down using an internal jumper.
Digital I/O transfer rate
(system-paced)
100 to 5000 port reads/writes or single bit reads/writes per second typ, on local
network (Note 5)
Alarm functionality
Any combination of DIO bits may be configured to become outputs and go to defined
values when an Ethernet connection with a host is established or lost.
Power on and reset state
All bits are input unless the alarm functionality is enabled for them.
Input high voltage threshold
