REMOTE OUTPUT SIGNALS

Two output signals are provided for controlling external devices through unused pins on the
printer/serial connector. The pins are connected to the CPU board where jumpers may be
installed to activate the signals. Refer to Figure 13 for jumper locations. The output signals are:
Pass/Fail and End of Test, and are brought out on pins 24 and 25, respectively. A jumper also is
provided for supplying +5vdc at pin 23. The pin assignments and labels used on the CPU board
are as shown below:

The Standard Jumper settings, using W1 and W2, match the jumper
locations for the Model 256 and Model 256/PC testers. The Alternate
Jumper Setting, using W4 and W5 in lieu of W1 and W2, outputs the
signals on the same connector pins as the Model 512 jumper settings.
Refer to Figure 13 for jumper locations on the CPU board.
