Jumper Settings for Specific Devices
Table 1 lists the jumper settings for the range of devices that can be attached to the RS-232 card.
Refer to Figure 1 for the locations of the jumpers and their corresponding pin numbers. In the table below, 2-3 means you should place the jumper on
pins 2 and 3, whereas a designation of 1-2 means you should place the jumper on pins 1 and 2.

Setting Switches
Switches
Switch SW1 on the RS-232 card is a bank of eight DIP switches. From left to right (see Figure 2) 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 4100 communications line running between the card and the 4100 CPU. Set this switch
to ON.
•
SW1-2 through SW1-8.
These switches set the card's address within the 4100 FACP. Refer to Figure 3 for a complete list of the switch settings
for all of the possible card addresses.
Note:
You must set these switches to the value assigned to the card by the Programmer.
