The E-1608 offers high-speed analog input over an Ethernet inetrface, two analog outputs,eight digital I/O, and one event counter input.

Overview• Android™
• Linux®

The E-1608 features a high-speed Ethernet interface that provides continuous
real-time data transfers. The device offers four differential or eight single-ended
analog inputs, and two analog outputs – all with 16-bit resolution. With eight
digital I/O and one counter input, the E-1608 is a low-cost, high-performance
multifunction I/O DAQ device.

Ethernet Interface

Trigger Input

The E-1608 has a built-in 10/100 BASE-T
auto-negotiation, high-speed communication port. The networking protocols areTCP/IP and UDP.

The E-1608 has an external digital trigger
input. The trigger mode is software-selectable for edge- or level-sensitive mode.
Edge-sensitive mode can be configured for
either rising or falling edge. Level-sensitivemode can be configured for either highor low level. The default setting at power
up is edge-sensitive, rising edge.

Once connected to the network, the device
can be remotely accessed and configured
through software from anywhere on thenetwork. Only one user at a time canaccess the E-1608.
Software is required to actively communicate with the E-1608 over Ethernet. The
device does not operate as a standalone
data logger.

Analog Input
The E-1608 provides 16-bit analog inputs
that are software-selectable as four DIFFor eight SE inputs. The device supports
input ranges of ±10 V, ±5 V, ±2 V, and ±1 V
that are software-selectable per channel.

Analog Output
The E-1608 has two 16-bit, software-paced
analog outputs that can be updated at arate of 500 S/s. The output range is fixed
at ±10 V.

Digital I/O

Calibration
The E-1608 is factory-calibrated using aNIST-traceable calibration process. Specifications are guaranteed for one year. For
calibration beyond one year, return thedevice to the factory for recalibration.

E-1608-OEM Version
The E-1608-OEM has a board-only form
factor with header connectors for OEM
and embedded applications (no case or
network cable included). All devices canbe further customized to meet customer
needs.

Eight bidirectional digital I/O bits areindividually-configurable for input or
output. The digital I/O terminals candetect the state of any TTL-level input.
Bits can be configured for pull-up (+5 V) or
pull-down (0 V) with an onboard jumper.

Counter Input
One 32-bit event counter can count TTLpulses. The counter accepts inputs of up
to 10 MHz.

The E-1608-OEM has the same specifications
as the standard device, but in a board-onlyform factor with header connectors insteadof screw terminals.

Clock I/O
The E-1608 has one external clock input
and one clock output for analog inputs.
