The complete order number for the EVA2200-A is EVA2200-A The board will always be shipped with latest part number. Information on sales channels can be found on Lantronix’s web page. 1.4 Handling Precautions The EVA2200-A contains components that are sensitive to electrostatic discharge (ESD).
2 Quick Start (1) Connect the EVA2200-A with your PC using the included USB cable. (2) When the PC asks for drivers select the folder “Tools\Drivers” on the included CD ROM. Note: Two drivers need to be installed, the EVA2200-A FTDI driver and the serial driver.
2: Quick Start (6) Activate the correct port within GPS Cockpit. You can do this by selecting the “COM port connection” icon (left-most icon) or by choosing “Port Number” in the “Settings” menu. In both cases the following window will appear: Figure 6: GPS Cockpit COM Port Setting window Choose the COM port to which the GPS receiver is connected (verify in your system settings - device manager, which communication port is used for this...
2: Quick Start (7) Open the NMEA Terminal window to see NMEA sentences by using the “NMEA Terminal” window button. You will see no messages! (8) In order to start the module, you need to push the “ON” button of the evaluation board.
3 Potential Problems with Windows 3.1 Ballpoint Mouse After successful driver installation and after pushing the “ON” button of the EVA2200-A Windows might interpret the data coming over the serial interface as a serial ballpoint mouse! Your mouse pointer can start jumping around. To stop this, disable the according device using your device manager.
3: Potential Problems with Windows So please make sure that the “Color quality” within the “Display Properties” is set to “Highest (32 bit)”. “Display Properties” can be invoked by a right click on your desktop and selecting “Proper- ties”.

4 Board Overview The following picture shall give an overview on the complete evaluation board EVA2200-A. It explains the most important components and can be used as a ref- erence for the next paragraphs.

5 On-Board Peripherals 5.1 ON and RESET Push-Button The EVA2200-A has two push-buttons: • ON (ON / OFF functionality) • nRST (RESET functionality) After power on pushing the “ON” button will start the A2200-A module. This is ab- solutely necessary to get the module going. The “ON” button must be used as well in other cases, e.g.
5: On-Board Peripherals 5.3 LEDs There are 6 LEDs on the EVA2200-A that indicate different signals from the GPS receiver (order of LED’s on EVA2200-A from left to right): Name Function Description Transmit Serial data traffic (from GPS receiver) Receive Serial data traffic (into GPS receiver) 1PPS signal at rising edge (1 pulse per second, 1PPS...
6 Design-in Support The EVA2200-A Evaluation board offers the possibility to implement the A2200-A GPS receiver module temporarily into your design by using the terminal block with 15 connections. To operate the EVA2200-A via this terminal block, please check “Table 3: Switch settings”.
6: Design-in Support 6.2 DIP Switch Settings The following picture shows the DIP switches of the EVA2200-A. Figure 15: DIP switches (picture turned by 90° ccw) Operation via USB connector Operation via Switch Function (default settings) terminal block ON_OFF Table 3: Switch settings 6.3 ICC Jumper Figure 16: ICC jumper As long as the VCC DIP switch is “ON”...
7 NMEA Port • Default setting: 4800 baud, 8 data bits, no parity, 1 stop bit, no flow control! • Standard NMEA-0183 output on NMEA, baud rate selectable. • Standard USB connectors GPS SiRFstarIV Evaluation Kit EVA2200-A for GPS Receiver Module A2200-A User Guide...
8 Shutdown Sequence Care must be taken to implement an orderly shutdown sequence along with sup- plying power for a certain period of time after initiating the shutdown sequence. Ab- rupt removal or drop of power while the module is running has risks ranging from minor impact on TTFF to fatal, permanent corruption of flash memory code area! The shutdown sequence can either be initiated by a command (NMEA or binary) or by toggling the ON_OFF pin.
9 Board Schematics The following shows the schematics of the EVA2200-A. For best readability the picture was enlarged to cover the complete page. Please note that the design is done in a way that it reflects the Minimum Configura- tion as outlined in the GPS Receiver Manual A2200! These are especially: •...
