Connect the FSM-9 with an arduino

[Adrian Cuellar]

Hello everyone.

I am trying to connect the FSM-9 with an arduino. Through the SPI interfaces. I recive the following line of the FSM-9 on the monitor serial. 

Has anyone used the SPI interface on this module. The arduino code i have is as below.

6 22 0 4 9 194 3 3 129 162 152 0 15 0 0 0 0 0 0 0 1 0
