E2 Brain uses half counts for DA4, DA4T, and DA6 modules

Applies To:

Versions Affected:

Problem affects versions: Firmware R1.1d and lower
Problem is fixed in version: R1.1e

Resolved In Version:

Problem is fixed in version: R1.1e

Symptoms:

When an E2 brain board is used with a DA6, DA4 or DA4T analog output module, instead of counts ranging from 0-4095 as normal, they range from 0-2047.

If you are reading counts, they will show only half the actual counts. If you are writing counts, you must write half the counts you want in order to output the desired value.

Workaround:

For these modules, multiply counts read by 2 to produce the correct value. When writing to these modules, divide the desired value by 2 to determine the value to send.
