Configuring the card consists of selecting the shield tie point, and setting the card address.
If a shielded cable is used, connect the cable shield to the dedicated terminal on TB1 and
use jumper port (P1) to select where the shield will be tied.
• Position 1 - 2 connects the shield to 0 V.
• Position 2 - 3 connects the shield to Earth.
The card address is set on DIP switch SW1, which is a bank of eight switches (see figure
below). From left to right, these switches are designated as SW1-1 through SW1-8. The
function of these switches is as follows:
• SW1-1. This switch sets the baud rate for the internal communications line
running between the card and the CPU. Set this switch to ON.
• SW1-2 through SW1-8. These switches set the card’s address within the
4100U-S1. Refer to the table in Appendix A for a complete list of the switch
settings for all of the possible card addresses.
Note: You must set these switches to the value that was assigned to the card
by the 4100U Programmer.
