Overview
Maintaining signal connections is one of the most important factors in ensuring that
your application system is sending and receiving data correctly. A good signal con-
nection can avoid unnecessary and costly damage to your PC and other hardware
devices. This chapter provides useful information about how to connect input and
output signals to the PCIE-1840 cards via the I/O connector.

Setting the BoardID Switch (SW1)
The PCIE-1840 has a built-in DIP switch (SW1), which is used to define each card's
board ID. You can determine the board ID on the register as shown in Table 3.1.
When there are multiple cards on the same chassis, this board ID setting function is
useful for identifying each card's device number through board ID. We set the PCIE-
1840 board ID as 0 at the factory. If you need to adjust it to other board ID, set the
SW1 by referring to DIP switch setting.
