QUICK START PROCEDURE
HARDWARE SETUP
Connect the DC1012A to a DC590 USB serial controller
using the supplied 14-conductor ribbon cable. Connect
the DC590 to host PC with a standard USB A/B cable.
Run the evaluation software supplied with the DC590 or
downloaded from www.linear.com/software. The correct
program will be loaded automatically. Click the COLLECT
button to start reading the input voltage. The software
allows for selecting the input channel, single ended or dif-
ferential mode and 50Hz/60Hz rejection settings. Selecting
2
× speed located at the bottom of the strip-chart display
will double the data output rate at the expense of offset
accuracy (LTC2499 and LTC2495 only).
Tools are available for logging data, changing reference
Tools are available for logging data, changing reference
voltage, changing the number of points in the strip chart
and histogram, and changing the number of points aver-
aged for the DVM display.

Analog Connections
Analog signal connections are made via the row of turret
Analog signal connections are made via the row of turret
posts along the edge of the board. Also, if you are connect-
ing the board to an existing circuit, the exposed ground
planes along the edges of the board may be used to form
a solid connection between grounds.
