2.2 Installation of two expansion cards
Two expansion cards can be mounted in some terminals. They are mounted in
parallel to the connector on the CPU card in the terminal. Two expansion cards
can be connected via one expansion cable since there is a parallel contact on the
cable. The connector in the middle is used for the expansion card placed in Slot
1, and the end connector is used for the expansion card placed in Slot 2. If only
one card is used either connector can be used.
The connector X1 on the expansion card in Slot 2 is connected to the connector
X1 and the CPU card in the terminal via the X1 connector on the expansion
card in Slot 1. If the X2 connector on the CPU card in the terminal is used by
any or both cards, this connector is connected to the X2 connector on the
expansion card.
When two expansion cards are mounted in the same terminal you mount the
card in Slot 1 with the distances and the card in Slot 2 with the screws in the
distances.
