MCC USB-205
The USB-205 is the fastest enclosed model in MCC’s USB-200 Series: eight single-ended 12-bit inputs at 500 kS/s, two 12-bit analog outputs, eight digital I/O lines and a 32-bit counter. It is the budget option when the 100 kS/s USB-201 and USB-202 are too slow.

Where the USB-205 sits in the USB-200 Series
The USB-200 Series shares one input design: eight single-ended channels, 12-bit resolution and a fixed ±10 V range. The USB-201 and USB-202 run at 100 kS/s, the USB-204 and USB-205 run at 500 kS/s, and the USB-202 and USB-205 add two analog outputs. The USB-205 has both upgrades, at $215 list at the time of writing. Digilent has retired the enclosed USB-201 and the USB-205-OEM board, while the enclosed USB-205 remains on sale.
Analog output and input limits
The two outputs are 12-bit, 0 to 5 V, and update at 250 S/s on one channel or 125 S/s per channel with both running. That is enough for setting a bias or a slow control voltage and too slow for waveform generation. The inputs are single-ended only, so keep cables short and reference sources to the device ground. The 500 kS/s rate is aggregate. The sample rate calculator shows how it divides across the channels you scan, and sample rate and aliasing covers how much margin to leave.
Software support
On Windows, MCC supports the USB-205 with InstaCal for setup, the Universal Library for programming and DAQami for logging. On Linux and macOS, uldaq supports it too, so you can script it in C or Python on a Mac or a Raspberry Pi. DAQAtlas, which is in development, runs it through uldaq with hardware-paced scans.
Questions
Does the USB-205 work on a Mac?
Yes. MCC’s uldaq library supports the USB-205 on macOS and Linux. MCC’s InstaCal and DAQami are Windows only.
How fast are the USB-205 analog outputs?
MCC specifies 250 S/s on one channel or 125 S/s per channel when both outputs are used.
Is the USB-205 rate per channel?
No. 500 kS/s is the aggregate rate, shared across the channels in the scan.
