Interface Wire List - Cablescan 4000C Instruction Manual

Model 4000C Instruction Manual

INTERFACE WIRE LIST

First, a Wire List for the test fixture harness is generated - for use in programming the User
Notation Table and also for fabricating the interface harness. For this example, all 22 pins can
be interfaced to a single tester connector since the Model 4000C uses 64-pin connectors. Test
points are consecutively numbered on the tester starting with J1 pin 1 through J1 pin 64.
Connector J2 pin 1 then begins with test point number 65. The Wire List below relates the point
number on the tester to the tester connector and pin, and the harness connector and pin.

Be careful when using interface cables between the fixture connectors and tester
connectors. If different connector types are used on opposite ends of the cables,
their pin numbering sequences must be considered. The connectors on the tester
are numbered with the odd pins on the top row and the even pins on the bottom
row. Pin 1 is at the upper right corner. Champ style connectors (often used as the
fixture connectors) are numbered with the first 32 pins numbered consecutively
across the top and the second 32 across the bottom. When the interface cables are
made using flat cable and these two connector types, pin 2 on the tester connector
is connected to 33 on the Champ connector, 4 to 34, 6 to 35, etc. To eliminate
translation problems, use flat cable pin numbering convention on the Champ
connector.
