PT100 DAUGHTER BOARD, Reading 2000 c for Heat Bed

[ScaraMan]

Hi
I recently purchased the PT100 Daughterboard latest version with jumpers.
I have some issues.
The reason why I bought this board, was to connect the Ultimaker 2 heatbed to the Duet wifi.
That’s all, but when I connect it reads 2000 C for the Bed, I am using rep rap firmware2.x
I followed the instructions on the web on how to configure firmware.
The 2 wires for power go to heatbed connector on Duet wifi , and the other 2 wires I have connected to PT 100 motherboard (2 and 3 on the first connector )
The jumpers are there on both connectors.
I am only using 1 connector for the heatbed only, not for my hotend ( since that is a e3d v6 no pt100 sensor )

Can you please tell me how to fix this issue ??
How to properly configure ??

Currently under the Heater section in config file I have this

M305 P0 X200 ; set thermistor + ADC parameters for heater 0
M143 H0 S65 ; set temperature limit for heater 0 to 80C
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1
M143 H1 S260 ; set temperature limit for heater 1 to 260C

@ScaraMan can you post a photo of your wiring?

@ScaraMan Hi,
Please post some information about the heating mat used on the print bed... which thermistor is installed there?
Then I would strongly recommend you to update to the latest firmware.
