Chapter 1
Introducing the USB-1616FS
The USB-1616FS is a USB 2.0 full-speed device supported under popular Microsoft® Windows® operating
systems.
The USB-1616FS provides true simultaneous sampling of up to sixteen 16-bit single-ended analog inputs.
Simultaneous input sampling is accomplished through the use of one A/D converter per channel. The module
features sampling rates of up to 50 kS/s per channel, and up to 9500 S/s per channel throughput for all channels.
You can configure the analog input range of each channel independently via software. An onboard temperature
sensor lets you monitor your environment temperature.
Eight digital IO lines are independently selectable as input or output. A 32-bit counter can count TTL pulses. A
SYNC (synchronization) control line lets you synchronize two USB-1616FS modules to acquire data
synchronously from 32 analog inputs.
The USB-1616FS is powered by an external +9 V unregulated power supply that is shipped with the board.
Power and USB connectors let you power and control multiple MCC USB Series products from one external
power source and one USB port in a daisy chain fashion.
The USB-1616FS is enclosed in a rugged housing that you can mount on a DIN rail or on a bench (see
Figure 1).

USB-1616FS User's Guide Introducing the USB-1616FS
Connecting a USB-1616FS to your computer is easy
Installing a data acquisition device has never been easier.
The USB-1616FS relies upon the Microsoft Human Interface Device (HID) class drivers. The HID class
drivers ship with every copy of Windows that is designed to work with USB ports. We use the Microsoft
HID because it is a standard, and its performance delivers full control and maximizes data transfer rates for
your USB-1616FS. No third-party device driver is required.
The USB-1616FS is plug-and-play. There are no jumpers to position, DIP switches to set, or interrupts to
configure.
You can connect the USB-1616FS before or after you install the software, and without powering down
your computer first. When you connect an HID to your system, your computer automatically detects it and
configures the necessary software. You can connect and power multiple HID peripherals to your system
using a USB hub.
You can connect up to four USB-1616FS devices to one USB 2.0 port. You can connect up to two devices
to a USB 1.1 port.
You can connect your system to various devices using a standard four-wire cable. The USB connector
improves upon serial and parallel port connectors with one standardized plug and port combination.
Data can flow two ways between a computer and peripheral over USB connections.
