Страница: 17 / 20

P3 (3 on the Picture 3) – 10-pin IDC connector to connect the Power Probe with the IOM6-ADIO
using provided 10-pin ribon cabble.
P4 and P5 (4 and 5 on the Picture 3) – Power supply output towards the target.
ST1 (6 on the Picture 3) – BNC connector
JB1 (7 on the Picture 3) – Jumper block for selecting different shunt resistors.
NOTE:
1) Excessive current will burn the resistors.
2) Never set more than one jumper!
3) Selected shunt resistors must handle the heat generated by the power dissipated on them.
Three of the five available positions are populated with resistors:
Position Shunt Resistance Shunt Resistance including JB1
0.25 A 1.00 Ohm 1.00 Ohm
1 A 0.25 Ohm 0.26 Ohm
2.5 A 0.10 Ohm 0.11 Ohm
The remaining two positions are available for a custom user setup with unpopulated resistors
R5 and R6.
NOTE: With lower shunt resistor values also the JB1 jumper resistance starts to play a role and
may influence the measurement. This can be easily compensated by slightly increasing the
shunt resistance value in the winIDEA setup dialog, by 0.01Ω, for example.
JB2 (8 on the Picture 3) – Jumper block for selecting different voltage ranges.
NOTE: Never set more than one jumper!
Three of the five available positions are populated with resistor dividers:
Position Resistors
Voltage Multiply
(winIDEA configuration)
5 V 0/10 kΩ 1
10 V 10/10 kΩ 2
20 V 30/10 kΩ 4
The remaining two positions are available for a custom user setup with unpopulated resistors
R12 and R13. The lower part of the voltage divider is set by the R9 of 10kΩ.
SW1 (9 on the Picture 3) – Switch connecting/disconnecting P1/P2 connectors with P4/P5
connectors respectivelly “power on switch” for the embedded targeted connected to P4 or P5
connector.
LD1 (10 on the Picture 3) – LED indicator. Note that the LED needs a very small current to light
and may glow because of a parasitic current flowing, for example, even when the emulator
switched on and the target is off.
Connection Procedure
1. Make sure that the Embedded system and BlueBox are not powered.
2. Switch SW1 is in OFF position.
