ASCII COMMAND RING BUFFER COMMUNICATION INTERFACE
MAXnet User’s Manual 3-3
3.3. 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. 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 sending data over the communications channel (Ethernet or RS-232) being used.
3.5. DYNAMIC LINK LIBRARY
The OmsMAXnet.dll is the Motion Control Dynamic Link Library (DLL) that provides the means to create
C, C++, MFC or Visual Basic applications, running under Windows NT, 2000 or XP. The DLL supports
communicating to MAXnet via Ethernet or Serial port and supplies a set of wrapper APIs round the more
commonly used motion controller commands. From the basic Send and Query to issuing multiple axes
moves can be achieved using the DLL with minimal lines of code. The API manual “
