Hardware Guide 2.1 Power Supplies The PGA4311-EVM includes a power supply connector, labeled J4 on the circuit board. Four locking terminals are provided for the analog power supplies (VA+ and VA–), a digital power supply (VD+), and a common ground (GND). There are two configuration modes for the power supplies: ThreeSupply operation and Two-Supply operation. In the case of Three-Supply operation, jumper J1 is installed while jumper J2 is an open circuit.
Hardware Guide 2.5 Register Loop-Back Jumper The evaluation module contains a loop-back jumper, labeled SDO_R. The purpose of this jumper is to allow read back of the gain register values. This is helpful when diagnosing problems with the PC parallel port interface or host controller communications. The serial interface is basically a 32 bit serial IN, serial OUT shift register. The SDI pin is the input, while SDO is the output.

Chapter 3 Software Guide This chapter provides information regarding evaluation software installation and application. Software control panel operation is described in detail, with graphics of each panel providing a visual reference. Note: The PGA4311-EVM utilizes the applications software created for the PGA2310EVM. Where needed, differences in operation between the PGA4311-EVM and PGA2311EVM will be explained in more detail. Topic Page System Requirements ..............................................
Software Guide 3.1 System Requirements The supplied software will operate on personal computers designed for use with Windows 95 and 98. A CD-ROM drive is required for installation of program files and access to support documents. Approximately 4MB of hard disk space is required for installation. 3.2 Installation Procedure The following procedure assumes familiarity with navigating the Windows desktop to find folders and files located on mounted volumes.
Software Guide 3.4 Determining and Setting the Printer Port Address The parallel port address for your PC can be found by going to the Start menu and selecting the Control Panel item in the Settings menu. When the Control Panels window opens, find the System icon and double click it. From the System window, select the Device Manager tab by clicking on it once. Scroll down the list of devices until you see the Ports entry. Double click on the Ports entry to list the PC ports.
Software Guide 3.6 Gain Controls The Gain Controls occupy the bottom half of each DUT panel. There are three gain sliders, including one each for left and right channel, and a Gang slider for controlling both channels simultaneously. The DUT1 panel controls Channels 1 and 2 of the PGA4311, with Channel 2 corresponding to the right channel, and Channel 1 corresponding to the left channel.
