1 Introduction 1.1 Purpose The GPS Evaluation Kit EVA1035-H allows an easy evaluation of Vincotech’s GPS receiver /smart antenna module A1035-H by offering quick access to the ports of the module.
2 Handling Precautions The EVA1035-H contains components that are sensitive to electrostatic discharge (ESD). Please handle with appropriate care. 3 Quick Start (using USB connection) (1) Connect the EVA1035-H 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 that two drivers need to be installed, the EVA1035-H FTDI driver and the USB serial driver.
Update Driver Disable Uninstall Scan for hardware changes Properties Figure 2: Disabling of Microsoft Serial BallPoint (3) Either assure that the on-module GPS antenna has good view to the sky or connect the included GPS antenna to the EVA1035-H via the external antenna connector and make sure this active antenna has a good view to the sky! Make sure the right antenna input is activated by setting the ANT_SW DIP to the “OFF” position fgor the on module antenna or to the “ON” position for the external anten
Figure 4: GPS Cockpit communication window – COM2 The connection is established now. (6) Open a terminal window to see NMEA sentences by using the “NMEA Terminal” window button. You should then see messages like this: Figure 5: GPS Cockpit NMEA terminal with NMEA data Now you can start using all the other windows and features of GPS Cockpit. Please refer also to the GPS Cockpit manual and the online help within GPS Cockpit. V1.
4 On-Board Peripherals 4.1 RESET and ON_OFF Push-Button The EVA1035-H holds two push-buttons: • • nRST (RESET) ON_OFF The nRST button is used to get a full reset of the GPS module. All parameters are stored in non-volatile memory. After pushing this button the module starts again from the beginning. The ON_OFF button puts the A1035-H GPS receiver into Hibernate state if it is on and wake up if it is in sleep state. During sleep state the receiver draws 20µA typically and maintains RTC and SRAM.
Further information is given in • Chapter “6.2 DIP Switch Settings” and • Vincotech’s GPS Receiver A1035-H Product Manual 4.2.1 Hints If the external antenna input is not used it should be terminated with 50 Ω ± 20%. Do not feed antenna supply voltage into terminated antenna inputs. V1.
5 LED’s There are 6 LED’s on the EVA1035-H that indicate different signals from the GPS receiver (order of LED’s on EVA1035-H from left to right): LED Name Function Description LD2 LD1 RX TX Receive Transmit LD4 ON_OFF Hibernate LD5 1PPS Timing LD3 RFPWUP RF/analog status LD6 Power / VCC POWER Serial data traffic (into GPS receiver) Serial data traffic (from GPS receiver) Toggle hibernate mode / position request during PTF cycle (the LED visualizes the ON_OFF pulse) 1PPS signal at rising
6 Design-in Support The EVA1035-H demo board offers the possibility to implement the A1035-H GPS receiver module temporarily into your design by using the terminal block with 9 connections. To operate the EVA1035-H via this terminal block, please check “Table 3: Switch settings”. Please note: • VCC power input is not protected against reversed polarity • External supply has to be within the range of 3.3 to 3.6 VDC • RTC backup: Supercap soldered to the board can be used (*1) 6.
6.2 DIP Switch Settings The following picture shows the DIP switches of the EVA1035-H.
6.3 ICC Jumper Figure 10: ICC jumper As long as the VCC DIP switch is “ON” the ICC jumper is bridged. By switching off the VCC switch the current draw of the A1035-H GPS receiver can be measured directly by connecting a low resistance measurement device to the ICC jumper.
