The E-1608 offers four differential or eight single-ended analog inputs, two analog outputs,
eight digital I/O, and one event counter input.
Overview
Analog Input
The Ethernet-based E-1608 is a low-cost,
high-speed, multifunction I/O DAQ
device that measures eight analog channels at 250 kS/s aggregate with 16-bit
resolution.
The E-1608 provides 16-bit analog
inputs that are software-selectable as
four DIFF or eight SE inputs. The device
supports input ranges of ±10 V, ±5 V,
±2 V, and ±1 V that are software-selectable per channel.
This device also offers two analog outputs, eight digital I/O channels, and one
counter input.
Ethernet Interface
The E-1608 has a built-in 10/100 BASE-T
auto-negotiation, high-speed communication port. The networking protocols
are TCP/IP and UDP.
Once connected to the network, the
device can be remotely accessed and
configured through software from anywhere on the network. Only one user at
a time can access 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 Output
The E-1608 has two 16-bit, softwarepaced analog outputs that can be
updated at a rate of 500 S/s. The output
range is fixed at ±10 V.
Trigger Input
The E-1608 has an external digital trigger input. The trigger mode is softwareselectable for edge- or level-sensitive
mode. You can configure edge-sensitive
mode for either rising or falling edge. In
level-sensitive mode, you can configure
for either high or low level. The default
setting at power up is edge-sensitive,
rising edge.

E-1608-OEM Version
Eight bidirectional digital I/O bits are individually-configurable for input or output. The digital I/O terminals can detect
the state of any TTL-level input. You can configure for pull-up
(+5 V) or pull-down (0 V) with an onboard jumper.
The E-1608-OEM has a board-only form factor with header
connectors for OEM and embedded applications (no case, CD,
or network cable included). All devices can be further customized to meet customer needs.
Counter Input
One 32-bit event counter can count TTL pulses. The counter
accept inputs of up to 10 MHz.
Clock I/O
The E-1608 has one external clock input and one clock output
for analog inputs.
Calibration
The E-1608-OEM has the same specifications as the standard device,
but in a board-only form factor with header connectors instead of
screw terminals.
E-1608 devices are factory-calibrated. Specifications are guaranteed for one year. For calibration beyond one year, return
the device to the factory for recalibration.
