physical connection between ARDUINO and LTC6804-1

Hello

I'm working on a project in which I need to read data from demo board of LTC6804 (DC1894) by an ARDUINO UNO. I have only one board and therefore, the 4 wire SPI mode is activated (all the jumpers on DC1894 are on 0 state).I'm sure that the code is correct; however it sends 0 instead of correct value for cell voltage. So, it seems that LTC6804-1 is not communicating with ARDUINO; I checked the SCLK, SS and also MOSI pins by oscilloscope; they are working; however, the pin MISO always stays at zero. So, I thought maybe the problem is with physical connections:
Now, I have made following connections between to boards:
GND to GND
MISO to MISO
MOSI to MOSI
SCLK to SCLK
CS to CS

The SPI socket on DC1894B has 14 pins, is there any other pin that I need connect to corresponding pin on ARDUINO? Or, do you have any idea where is wrong probably? Please help me on this because I'm very tight on time.

Thanks in advance

Hello again

Sorry for replying; I found the missed connection: a resistor (in the order of 5k) must be connected between VCC of microcontroller and the MISO line. (Datasheet of LTC6804; Figure 18c; page 41). It works perfectly.

Thanks,
