System Requirements • An open ISA slot WARNING! ISA cards, like all computer equipment, can be severely damaged by static electricity. Be sure that you are properly grounded before opening your computer case or touching your ISA card. StarTech.com recommends that you wear an anti-static strap when installing any computer component. If an anti-static strap is unavailable, discharge yourself of any static electricity build-up by touching a large grounded metal surface (such as the computer case) for several seconds. Also be careful to handle the ISA card by its edges and not the gold connectors. Contents This package should contain: • 1 x ISA serial card 2

the instructions carefully and complete each step in the order listed. NOTE: If you want to configure your card in a manner that is different from the default you will need to adjust the jumpers before installing the card. See “Setting The Jumpers” on page 4. Installing the Card 1. Make sure that your system is unplugged and you are grounded. 2. Remove the cover of your system (see your computer's user manual for details, if necessary) and gently turn your computer onto its side. 3. Locate an empty ISA slot (usually black in colour) and remove the metal plate that covers the rear bracket. You may need a Phillips screwdriver to perform this step. Hang on to the screw! You will need it to secure the card later. 4. Gently insert the card into the empty slot, making sure it is firmly seated. 5. Secure the card in place using the screw you removed in Step 3. 6. Put your computer case back on.

There are three sets of jumpers that can be configured on your card: reference transfer rate, COM address, and IRQ address. Reference Transfer Rate There are three possible transfer rate settings (labeled 1, 2, and 4) for each COM port. Each pin corresponds to the following transfer rate: Set the transfer rate for each port by setting the jumpers according to the following example: In the example above, Port A has been set to 460.8Kbps and Port B has been set to 230.4Kbps. 1 2 4 1 2 4 COM A COM B Pin Rate 1 115.2 Kbps (default) 2 230.4 Kbps 4 460.8 Kbps

1. Find an available COM Address on your system. Consult the user manual that came with your OS for instructions, if necessary. This card supports COM Addresses 1 through 7. 2. Set the COM Address for each port by placing the jumpers according to the following example: In the example above, Port A is set to COM 1 and Port B is set to COM 2. The base addresses are as follows: 5 A B 1 2 3 4 5 6 7 COM 1 3F8-3FF Hex COM 2 2F8-2FF Hex COM 3 3E8-3EF Hex COM 4 2E8-2EF Hex COM 5 2F0 Hex COM 6 3E0 Hex COM 7 2E0 Hex
