Figure 2-1 Relay Handler Interface
2.2.2 Electronic Start-Test
Start-test relay power is obtained from the handler. Jumper the header pins on the
Handler PC Board labeled “HANDLER 12V”. Be sure system main power is turned
off before removing the PC board. Wire 12 volts from the handler to pin 24 on rear
panel handler I/O connector. Start-test return is pin 25 (see handler connection table,
Figure 2-1, or Handler schematic). To start a test, handler should pull pin 25 to
ground with respect to handler 12 volts. Use EOT, EOT return, fail or bin, and diode
polarity results as required. Note that EOT has a separate return which may need to
be tied to handler common (dependent on handler). Make connection to handler
from the 5000 Series Tester using standard 25-pin D type connector cable. Use
TRW cinch type DBM-25P for solder connections, 3M P/N 3482-1000 for ribbon
cable, or other equivalent.
