5.6. Visual Pattern-Stimulator Adapter Repair

Pattern-stimulator adapter is examined externally for cable failure detection (Fig. 13).

Circuit control from the jack side is impossible. It is necessary to open cable jack unit
and check the montage. If the failure is not detected, open the jack unit from the
monitor side and measure the resistance of each cable. If the cable break is detected,
see the instructions on USB cable repair (see chapter 5.3 “Computer Interface Cable

Repair (USB cable)).

Fig. 13. Electrical schematic of pattern-stimulator adapter cable.
