Figure 21: Unloader Socket
Located below the power supply socket in the back of the equipment is I/O PORT2. Connect the connector, and there are three sets
of different colored wire pairs at the connector end. These are: Black-Green (X4B) for receiving READY board request signal from
the Unloader, Red-Blue (Y26) for sending board unload signal to the Unloader and the Yellow-White (Y25) TEST PASS signal
connector. Connect the Black-Green connector with the Unloader’s connector for sending READY board request signal. Then
connect the Yellow-White connector with the Unloader's connector for receiving TEST PASS signal. (We use the standard SMEMA
signal. If this is different due to differences in manufacturer, contact the rear stage manufacturer to acquire the connection data.)
