Controlling Di-149 via java
Problem: Hi, I need to control the DI-149 device via java but am struggling to find how to do this. I'm capable of recognizing the device as a COM port and have the list of protocols but am failing to send or receive any information. Thanks for your help!
Solution: See topic http://support.dataq.com/viewtopic.php?f=5&t=5479 for information that may be helpful. The DI-155 protocol is very similar to the DI-149, which does not respond to gains in the slist command and in the BInary Analog Channel Coding replaces the low order two data bits with the D0 and D1 digital inputs. If the operating system is Windows and your Java generates 32-bit code, it would probably be easier to link directly to the Win32 SDK documented on https://www.dataq.com/resources/installations/web-help/sdk/, which works much like DataqSdk.ocx without requiring a form to host the ActiveX control. It supports data averaging specified by counter values in the input list.
