COMMUNICATION INTERFACE DYNAMIC LINK LIBRARY MAXp User’s Manual 3-5 3.4.4. COMMAND ERROR (PREVIOUSLY STATUS REGISTER COMMAND ERROR BIT) The command error bit is ODBR bit 24 and it is cleared when the host writes a ONE to it. 3.4.5. ASCII COMMAND RING BUFFER (PREVIOUSLY OUTPUT SIDE OF DATA REGISTER) Command characters strings from the host are transferred to the controller by placing it in the ASCII Command Ring Buffer and updating the buffer insert pointer. 3.4.6. ASCII RESPONSE RING BUFFER (PREVIOUSLY INPUT SIDE OF DATA REGISTER) This ring buffer is resident in the Common Memory area region and the Message Unit’s Outbound Message Register 0 (OMR). Data is sent from the controller to the host by placing data into the ring buffer and then using OMR to notify the host that data is available. 3.5. DYNAMIC LINK LIBRARY OMS provides a Motion Control DLL for Windows NT, Windows 2000 & Windows XP operating systems. These DLL's function with the drivers to provide a rich set of commands for use in various motion control environments. The latest versions of the DLL’s are included on a CD-ROM with the shipment of the MAXp Controller card. Also included is a .PDF version of the User Manual. The .PDF version of the MAXp User manual and the support software is also available from the OMS Web site (www.pro-dex.com). The omsMAXpmc.dll is the Motion Control Dynamic Link Library that provides a means for C, C++ and Visual Basic applications, running under Windows NT, to communicate with Oregon Micro Systems PCI motion controllers. The DLL supplies a set of functions that provide “single function call” solutions to some of the more common motion control problems. For added flexibility other functions are also provided to allow the application to interact with the controller at its most basic text command string and text response string level. The document omsMAXpmc.txt or omsMAXpmc.doc supplies a description of each function, function calling conventions, and code samples. These are available on the support software CD-ROM or on our web site.
