JUMPERS TABLE
Description Jumper Utilization
External power input J5 Inputs from external power supply
Current measurement J3 Outputs to DVM
-12V isolation from the system JP4 On = voltage from system, Off = from Ext. supply
+12V isolation from the system JP6 On = voltage from system, Off = from Ext. supply
+5V isolation from the system JP5 On = voltage from system, Off = from Ext. supply
+VIO connection to the system through the extender JP10 On = VIO from the system, Off = from UUT plane
If this jumper is removed the UUT VIO signals must
be connected to the main voltage plane.
+3.3V source JP7 On-board = Between 1 & 2, from system = 2 & 3
Square pad on the 3 pin jumper is pin 1.
+5V current limit selection JP2 On = 2A, Off = 10A
VRG JP30 On = voltage from system
-SELVBATRTN JP31 On = voltage from system
-SELVBAT JP32 On = voltage from system
-VBAT JP33 On = voltage from system
VBATRTN JP34 On = voltage from system
VRGRTN JP35 On = voltage from system
LEDs
There are two sets of LED on the board, green and red. Each LED has a label which Voltage it represents. The green
LED, when illuminated, indicates presence of the corresponding voltage. The red LED, when illuminated, represents a
short on the corresponding voltage. Please note that the green LEDs do not necessarily indicate if the voltage is at the
expected level or not.
