E. FUNCTION MENU LAYOUT(see inside back cover)



F. VISION & LIGHTING

Normal fiducial detection is by an enhanced correlation technique that has been optimised todetect pre-programmed fiducial shapes referred to as ‘Synthetic’ fiducials. A ‘Video Model’standard correlation technique is provided to cope with fiducials for which a pre-programmedshape does not yet exist.Synthetic fiducials are programmed by selecting one of the pre-programmed shapes & enteringnumerically set dimensions. Alternatively the shape can be superimposed on actual fiducial &adjusted to fit. Currently available shapes are: circle, rectangle, diamond, triangle, cross anddouble square. A major advantage of this method is its independence of optical variationsbetween different machines, making the full transfer of product settings between printers possible.Other advantages of this method are increased accuracy, increased tolerance to variations infiducial size and rotation.Video Model fiducials are selected rectangular areas of the image containing the fiducials.Correlation or template matching, as it is also called, is used to locate the position in an image thatgives the best match to the stored video model. The advantage of this method is that it can be usedwhere a synthetic shape does not exist.

G. VISION LIGHTING

This vision system is very tolerant of lighting variations, but it is still important to achieve a goodquality image to give the best results. For flat tinned copper or plain copper fiducials, the bestresults are obtained with vertical lighting. Domed tinned or fiducials covered with solder resist arebest viewed using light from a wide angle. The 265 has two optional lighting systems, a verticalilluminator and a ring illuminator enabling selection of the best lighting for any application.

n Received Diagnostic Loopback

The 265 receives a loopback diagnostic request, stream 2 function 25, containing a binary stringand responds, at any time, with a loopback diagnostic data message, stream 2 function 26,containing the received binary string.

n Host Are You There Request

The 265 sends an “Are You There” request, stream 1 function 1. The host responds with an onlinedata message, stream 1 function 2, containing a zero length list. If the timeout expires before anonline data message is received the 265 will assume that the host is off line.

n Host Diagnostic Loopback Request

The 265 will send a loopback diagnostic request, stream 2 function 25, containing a binary string.The 265 will wait for a loopback diagnostic data message, stream 2 function 26, containing thetransmitted binary string. If the timeout expires before the response message is received the 265will assume that the host is off line.

n System Status Change

Whenever the status of the 265 changes a discrete variable data send message, stream 6 function 3,will be sent containing one of the equipment state identifiers listed previously in send equipmentstatus.

n Upload Management Information

The 265 receives a data transfer request, stream 6 function 7, requesting management information.If the 265 is unable to process the request, because it’s current system state is not ready or anyother error condition exists, it will respond with a data transfer message, stream 6 function 8,containing a zero length item. If the 265 is able to process the request the message will contain thecurrent 265 management information data.



n Send Current Product Identify

The 265 receives a process program ID request, stream 7 function 7, and responds with a processprogram ID data message, stream 7 function 8, containing product name.

n Send Directory of Products

The 265 receives a current equipment process program directory request, stream 7 function 19,and responds with current equipment process program directory data message, stream 7 function20, containing a list of all the product file names stored on the 265.

n Erase Product
