Ensure that all power is off to the emulator and the user system.
Insert the cable head into the socket on the user system.
Note: Depending upon the package, it may be possible to orientate this cable head in any position on the socket,
so care should be taken to correctly identify pin 1 on the emulator and socket when installing.
Screw the cable head to the socket with the screws provided. Progressively tighten the screws in the sequence
shown in figure 2.5 until all are ‘finger tight’.

Note: Be careful not to over-tighten the screws as this may result in contact failure on the user system or
damage the cable head. Where provided, use the ‘solder lugs’ on the QFP socket to provide extra
strength to the emulator/user system connection.
