DAS-4300 Series Addendum

This document describes changes made to the DAS-4300 Series boards in
order to achieve compliance with the European EMC directive 89/336
EEC (CE Mark certification). In addition, this addendum provides
corrections to the DAS-4300 Series documentation.


Clock Output

Pins 5 and 12 of U514 (74ABT125) have been lifted in order to disable
the clock output function. If you connect multiple DAS-4300 Series
boards and want to use one internal clock for all the boards, you need to
replace the pins.


Spring Gaskets

Spring gaskets have been installed over the BNC connectors. When a
cable is attached, these gaskets are compressed between the cable
connector and the bracket.


Manual Corrections

The DAS-4300 Series Function Call Driver User's Guide states
incorrectly that the start trigger should be external when using an about
trigger. The start trigger must be internal when using an about trigger.




Part No. 24682; Revision A 1
The following information is missing from the description of the pCount
parameter of the K_IntStatus function in the DAS-4300 Series Function
Call Driver User's Guide:
q Normal acquisition
pCount = 0 during the operation
pCount = buffer length (total number of samples acquired) when the
operation completes
q About-trigger acquisition
pCount = 0 during the operation
pCount = pre-trigger length (number of samples acquired before the
about trigger occurred) when the operation completes
