INTF3000+ Analog Devices

Evaluates: EV Kits Requiring SPI/ INTF3000 Interface Board Parallel to USB Interface General Description Quick Start The INTF3000 interface board is designed to facilitate the Required Equipment interfacing of Maxims evaluation kit (EV) boards to any This section lists the recommended equipment to verify personal computer (PC) through the USB port. the operation of INTF3000. There are three different connectors on the INTF3000 1) INTF3000 interface board interface board available to communicate with the EV 2) PC equipped with Microsoft Windows XP , board: INTF2300, INTF2400, and DB25 (LPT) parallel Windows 7, Windows 8 OS and a USB port connector. The INTF2400 connector is intended for new designs, while the INTF2300, INTF2400, and DB25 parallel 3) USB-A male to USB-B male cable connector can support legacy EV boards that are already 4) Optional: ribbon cable configured for one of these types of interfaces. It must be 5) Optional: DC supply capable of delivering 2.0V to noted that legacy EV boards that were designed to com- 5.0V and 10mA current municate with the PC through DB25 parallel port must also have an updated control software which supports the Procedure INTF3000 interface board. The interface board is fully assembled and tested. Follow All three connectors on INTF3000 interface board sup- the steps below to verify board operation: port logic levels from 2V to 5V. The INTF3000 requires 1) Connect the INTF3000 to the PC using a USB-A no special driver installations on the host PC. The board cable to USB-B male cable. connects to the PC with a standard USB cable. 2) Connect to the EV board to the INTF3000 using either DB25 parallel port connector directly or through ribbon Benefits and Features cable connected between INTF2400/INTF2300 Parallel Port-to-USB Interface connector. This depends on what type of connector Serial port interface (SPI) to USB Interface is present on the EV kit. Supports Wide Voltage Range: 2V 5V 3) Connect JU1 in V position to drive everything INTF2400 Connector Compatible with Old INTF2400 BUS from 5V from USB. LPT Port Boards Addressing Enables the Use of up to Four Boards on 4) Alternatively, connect JU1 in V position to bias DEV a Single PC the drivers from EV board V pin, if V is routed DEV CC to V . DEV Ordering Information appears at end of data sheet. 5) If JU1 is removed, an external supply (V ) must be CC connected to the test point: V .
