The USB-200 Series provides improved cost/performance compared to our similarly
priced 12-bit DAQ devices. Each device provides eight single-ended (SE) analog
inputs, eight DIO channels, one event counter, and external pacer I/O.

• Android™

The USB-202 and USB-205 also provide two analog output channels.

Analog Input
USB-200 Series devices provide eight
12-bit SE analog inputs. The analog input
range is fixed at ±10 V.

Sample Rate
The maximum continuous scan rate is anaggregate rate. The following table lists
the maximum rate per channel when
scanning from one to eight channels.

Analog Output(USB-202 and USB-205)

External Pacer I/O

The USB-202 and USB-205 standard andOEM versions have two 12-bit analog
output channels. Both outputs can be
updated simultaneously at a rate up to125 S/s per channel. One output can beupdated at a rate up to 250 S/s. The output
range is fixed at 0 V to 5 V.

Max Rate Per Channel (kS/s)*

Each USB-200 Series device provides one
external clock input and one clock output for the analog input pacer. You canconnect an external clock signal to theexternal clock input terminal. When using
the internal clock, each device outputs
the ADC sample clock.

Digital I/O

USB-200 Series OEM Versions

USB-200 Series devices provide eight TTL-level digital I/O lines.
Each digital channel is software-selectable for input or output.
When configured for input, you can use the digital I/O terminals
to detect the state of any TTL‑level input.

OEM versions have board-only form factors with header connectors for OEM and embedded applications. All devices can befurther customized to meet customer needs.

When configured for output, each digital channel can source/
sink up to ±24 mA.

Pull-Up/Pull-Down Configuration
Each USB-200 Series device has a user-configurable internal
jumper to configure the digital bits for pull-up or pull-down(default).

Counter Input
Each USB-200 Series device supports one 32-bit TTL-level event
counter that accepts inputs up to 1 MHz.
The OEM versions have the same specifications as the standard
devices, but come in a board-only form factor with header connectors
instead of screw terminals.

Calibration
The USB-200 Series is factory-calibrated using a NIST-traceablecalibration process. Specifications are guaranteed for one year.
For calibration beyond one year, return the device to the factoryfor recalibration.
