Unpacking the USB-SSR08
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the USB-SSR08 from its packaging, ground yourself using a wrist strap or by
simply touching the computer chassis or other grounded object to eliminate any stored static charge.
If your USB-SSR08 is damaged, notify Measurement Computing Corporation immediately by phone, fax, or
email. For international customers, contact your local distributor where you purchased the USB-SSR08.

Installing the USB-SSR08
Before you connect the USB-SSR08 to your computer, configure the hardware and then connect the external
power supply that was shipped with the device. You can connect up to four MCC USB Series products in a
daisy chain configuration to a single USB 1.1 port or USB 2.0 port on your computer.
Configuring the hardware switches
The USB-SSR08 has three on-board switches that you set to configure the I/O module type, relay logic polarity,
and relay power-up state. Configure these switches before you connect the external power supply to the USB-
SSR08. Factory-configured default settings are listed in
. Refer to Fi for the location of each
switch.
