MAKING THE CONNECTIONS
This chapter describes the signal and control connections that the user can make between the

D-type connector protruding from the PC adapter slot corresponding to the chosen board position.
The metal shell is connected to the local PC chassis ground. All signals are referred to the relevant
signal ground.
