Installation
DIP Switch Settings
To change the DB9 Serial Ports between RS-232, RS-422, and RS-485, use the
respective Serial Mode Switch located on the Serial Card. Dip Switch 3 enables/
disables a 120 Ω Termination Resistor, used for impedance matching between the
Tx+/Tx- and Rx+/Rx- (RS-422/RS-485 4-wire) and D+/D- (RS-485 2-wire) lines. The
purpose is to prevent reections on the line that may cause signal errors.

Install the Card
Note: If the PCIe Card is to be installed into a Small Form Factor or Low-Prole
Desktop, it’s required to replace the pre-installed Full-Prole Bracket with the included
Low-Prole Brackets. The DB9 Serial Ports that use Ribbon Cables will need to be
installed on the separate Low-Prole Brackets.
1. Turn o the Computer and disconnect the Power Cable and any Peripheral
Devices that are connected (e.g. printers, external hard drives, etc.).
2. Remove the Cover from the Computer Case.
Note: Consult the documentation that came with the computer for details about how
to do this safely.
3. Locate an open PCIe Slot and remove the corresponding Metal Cover Plate(s) from
the rear of the Computer Case. In most instances, the Metal Cover Plate is attached
to the rear of the Computer Case with a single Phillips Head Screw. Save this
Phillips Head Screw for the next step.
4. Gently insert the Serial Card into the open PCIe Slot and fasten the Bracket(s) to
the rear of the Computer Case, using the Phillips Head Screw from Step 4.
5. (Optional) Connect SATA Power from the Computer Power Supply to the SATA
Power Connector, located on the rear of the Serial Card.
