5 / 19 page Maxim Integrated │ 5 www.maximintegrated.com Evaluates: EV Kits Requiring SPI/Parallel to USB Interface INTF3000 Interface Board Interface Connectors Parallel (LPT) Connector The parallel port connector is a DB25 connector wired to have the same pinout as a parallel port. This connector can be used to connect to legacy EV boards, which use the DB25 connector as shown in Figure 3. Table 8 shows the port pins associated with this connector. For legacy boards, if the DUT VCC < 3.3V, remove JU1 and connect test point VPULL to the same voltage as the EV board VCC; if the DUT VCC ≥ 3.3V, put JU1 in the VBUS position and no connection to VPULL is necessary.
