2.7ATX Power Control Connectors (J7 and J1)

2.7.1ATX feature connector (J7) and soft power switch connector (J1)

The PCA-6175 can support an advanced soft power switch function if an ATX power supply is used. To enable the soft power switch function:

1.Take the specially designed ATX-to-PS/2 power cable out of the PCA-6175's accessory bag.

2.Connect the 3-pin plug of the cable to J7 (ATX feature connector).

3.Connect the power on/off button to J1. (A momentary type of button should be used.)

Important: Be sure that the ATX power supply can take at least a 10 mA load on the 5 V standby lead (5VSB). If not, you may have difficulty powering on your system.
