BOOT jumper The BOOT jumper is for program upgrade. It shall be kept open for normal operation. When the BOOT is short, the GPS engine board is 3 CON20 REB-12R2 connector CON12 REB-2000/REB-2100 RESET switch BOOT jumper Open: Normal operation Short: Program upgrade P2 DGPS RTCM-104 port waiting for program upgrade and output nothing when running SiRF demo program. Please refer the program upgrade session for program update. DC input The power input can be DC input instead of using AC power core. The input range of the DC input is from 6.5V ~ 12V. We suggest you use +7.5V as the DC input. Reset It is used for external reset. VBT This is for RAM backup power of REB-2000/REB-2100 and REB-12R2. The
