ATX connector (CN10)
The ATX connector holds the three ATX-signals: PS_ON, PWR_GOOD and +5V Standby.
The layout of this connector is shown in the schematic. The function of the individual ATX signals
is shown in the table:
ATX signal Pin no Function
GND 1 System G ND
* 2 For fac tory use only
* 3 For fac tory use only
* 4 For fac tory use only
* 5 For fac tory use only
* 6 For fac tory use only
+5V STB 7 +5V Standb y
PWR_GOOD 8 This pin is 3.3V when +5V and +12V is OK
PS_ON 9 This pin m ust be pulled low in order to start PV-5127
GND 10 System GND
Ext. sensor connector (J2)
This connector is for an external ambient (system) temperature sensor, see section System
temperature. The input is designed for the Infineon KTY11-5 temperature dependent resistor
(Infineon ordering code Q62705-K245). Mating connector for J2 is Molex 7880-2. A ready-made
sensor with a 40 cm cable and connector is available as the PV-5127-TW40 accessory.
Batt. sensor connector (J1)
This connector is for an external battery temperature sensor, or a jumper, see section Battery
monitor and charger. The input is designed for the Infineon KTY11-5 temperature dependent
resistor (Infineon ordering code Q62705-K245). Mating connector for J1 is Molex 7880-2. A
ready-made sensor with a 40 cm cable and connector is available as the PV-5127-TW40 accessory.
From the factory, a jumper is installed, disabling the battery temperature control.
Pinheader (ST3)
This pinheader is for configuring the System temperature measurement, see section System
temperature. You can mount a jumper in the “10°C” position, in the “On-board sensor” position, or
you can leave it unconnected. The factory default is a jumper in the “10°C” position.
Jumper position (ST3) Input for System temperature
No jumper installed Sensor connected to J2
Jumper on ‘On-board sensor’ On-board sensor. Leave J2 unconnected.
Jumper on ‘10°C’ Simulate +10°C. Leave J2 unconnected. (Factory default)
