Reading CLK-DAT


i wanna read CLK-DAT from a device to Arduino to read 7-segments display data by Arduino


Which device ?
What is CLK-DAT ? Sounds like it could be clock data
How is it communicated ? Serial, maybe ?
What is the format of the data ?

device is satellite receiver
yes clock data
i need to read data to Arduino instead of 7-segments

Can you please provide a link to the device and if possible answer my other questions
