Handler Port Interface
THE HANDLER PORT INTERFACE USES SIMPLE TTL-COMPATIBLE SIGNALS TO CONTROL THE HANDLER. This
parallel port interface utilizes the 24 pin “D” connector on the side of the handler. It has been designed
to be compatible with “MCT-type” tester control interfaces.
The HANDLER PORT interface uses the addresses 00C0 through 00C7 for tester sort to output bin and
address 00BC for double test on/off selection. Please refer to the General Interface RAM Selections
section at the beginning of this chapter for further details.
