DC Power Input – P4 The uEZGUI‐EXP1 supports a 7VDC‐24VDC 1A (min) Power Supply. The connector is 2.1mm with center positive. Pin Number Description 7VDC to 24VDC, +/‐ 10%, 1 1.0A (min) 2 Power Supply Ground Serial Port – P3 The uEZGUI‐EXP1 Board includes one female DB9 Serial Port Connector. This connector may operate in either RS232 or RS485 (Full‐duplex) interface levels depending on jumper settings of JP1 through JP4. Jumpers JP1 – JP4 select the operating mode of the serial port; Jumper 1‐2 for RS232 levels, using UART0 Jumper 2‐3 for RS485 levels, using UART1 When operating as RS232, the serial port may also be optionally configured to support ISP programming of the LPC2478 using FlashMagic Software. To enable ISP programming, jumper JP6 & JP7 must be loaded. Note that with these jumpers loaded, operation of the LPC2478 may be affected by the RS232 interface signals. Refer to the FlashMagic user manual for details. Pin Number RS485 Mode RS232 Mode 1 No Connect No Connect 2 485_RDB‐ TXD (Output) 3 485_TDA+ RXD (Input) 4 ... -
Page 9: Usb Device - P1
USB Device – P1 The UEZGUI‐EXP1 Board includes one USB Device Interface allowing the unit to be connected to a USB Host, such as a PC. Through this connection, the uEZGUI represents a peripheral to the USB Host. The operational mode of the port is dependent on the software utilized (i.e. Mass Storage or Human‐ Interface). Note: The USB Device connector of the Expansion Board is connected in parallel to the USB Device connector of the uEZGUI Main board. To avoid damage or improper operation, do not connect both of these at the same time. The UEZGUI‐EXP1 Board may also be powered via the USB Device connector. Care must be taken to not overload the USB Host since 500mA is the maximum current allowable via USB. Pin Number Description 1 USB 5V 2 D‐ 3 D+ 4 NC 5 Signal Ground USB Host – P2 The uEZGUI‐EXP1 Board includes one USB Host Port allowing the unit to interface to various USB peripherals such as a USB Flash Drive (Thumb Drive). The operational mode of this port is dependent on the software utilized (i.e. driver support) Pin Number Description 1 USB VBus 2 ... -
