DLL - Custom Interface

The DLL is the tool-kit interface to connect custom applications to the jet.engine.

•  The DLL is a Component Object Model (COM) Application Programming Interface (API) library written in the C++ programming language
• Use the various COM objects in the DLL to control and monitor real-time printing on a jet.engine system
• Use any development environment that can link in a COM DLL
• Communicate with jet.engines using TCP/IP communications over 100 Megabit Ethernet
• Easy software setup using single file install program
• Sample client applications in Visual Basic 6 and C++ are included

The Demo Program communicates directly with the V4 Production Manager DLL. It uses COM event sinks in C++ to subscribe to events fired from the Production Manager DLL. The Demo Program creates the job and listens for, and responds to, events from the Production Manager DLL. It also has a serial interface that can receive commands and data from a client program and send status and requests back to the client program.

The Client Serial Program is a separate application whose only communication with the V4 Production Manager is over a serial communication line. It can issue a menu of commands. These commands are encoded in a structure that is sent over the serial line between programs. The Demo Programs unpack the structures and in turn issue the commands to the V4 Production Manager DLL. Status and requests from the V4 Production Manager DLL are packed into structures by the Demo Program and are written to the serial port for the Client Serial Program.
