USB-1616HS-2 User's Guide Installing the USB-1616HS-2

Configuring the hardware
All hardware configuration options on the USB-1616HS-2 are software-controlled. You can select some of the
configuration options using InstaCal, such as the analog input configuration (16 single-ended or 8 differential
channels), and the edge used for pacing when using an external clock. When measuring from thermocouples,
make sure you configure the channels for differential mode.
Once selected, any program that uses the Universal Library initializes the hardware according to these
selections.
Caution! Turn off power to all devices connected to the system before making connections. Electrical shock
or damage to equipment can result even under low-voltage conditions.
Information on signal connections
General information regarding signal connection and configuration is available in the Guide to Signal
Connections. This document is available on our web site at www.mccdaq.com/signals/signals.pdf.
Caution! Always handle components carefully, and never touch connector terminals or circuit components
unless you are following ESD guidelines in an appropriate ESD-controlled area. These guidelines
include using properly-grounded mats and wrist straps, ESD bags and cartons, and related
procedures.
Avoid touching board surfaces and onboard components. Only handle boards by their edges. Make
sure the USB-1616HS-2 does not come into contact with foreign elements such as oils, water, and
industrial particulate.
The discharge of static electricity can damage some electronic components. Semiconductor
devices are especially susceptible to ESD damage.
