2.14 ATX power control connector (JP1, J1)
2.14.1 ATX feature connector (J1) and soft power
switch connector (JP1)
The PCM-5864/E/L can support an advanced soft power switch
function, if an ATX power supply is used. To enable the soft
power switch function:
1. Get the specially designed ATX-to-PS/2 power cable
(PCM-5864/E/L optional item, part nos. 1700000450 and
1700000452).
2. Connect the 3-pin plug of the cable to J1 (ATX feature
connector).
3. Connect the power on/off button to JP1. (A momentary type of
button should be used.)
Important: Make 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.
