ANALOG DEVICES UG-004: Understanding EVAL-CONTROL BRD2Z/EVAL-CONTROL BRD3Z PC Interface Issues Manual

About this manual

This user guide addresses compatibility issues between the EVAL-CONTROL BRD2Z and EVAL-CONTROL BRD3Z (ECB) evaluation boards and the parallel port (LPTn) of a PC. It provides guidelines for configuring and testing the port(s) to ensure proper operation with Analog Devices ADC evaluation boards, specifically those using PulSAR high resolution SAR ADCs.

Frequently asked questions

What parallel port mode is required for the ECB?

The ECB requires at least one parallel port set in bidirectional mode, preferably ECP (Extended Capability Protocol) mode.

Can USB-to-LPT dongles be used with the ECB?

No, the use of USB-to-LPT dongles is not allowed because the GIVEIO driver needs a legacy LPT port.

What should be done if a RAM test failure occurs?

A RAM test failure is not related to LPT port problems and can usually be corrected by returning the ECB for a replacement.
