Please see Appendix A, Technical Specifications startingon Page 109 for mechanical drawings.3.2.1.3 Preparing the Data, Signal & Power HarnessThe wiring harness serves the following interconnect functions:• provide access to the serial communications ports• provide access to input and output timing strobes• provide power input(s)• provide access to control signalsFor all GPSCards, the power, status, and data inputs and outputs are accessed from a single connector.Therefore, the harness must be designed to mate with this connector.Figure 10 shows that the OEM4-G2L uses a 24-pin dual-row male connector with 0.5 mm square pinsand 2 mm spacing for the data, power, and status signals. The pin out for this connector is specified inSection A.2 on Page 110. The RF connector on the OEM4-G2L is an MMCX female.As shown in Figure 11, the OEM4-G2 uses a 40-pin dual-row male connector with 0.25” square pinsand 0.1” spacing for the data, power, and status signals. The pin out for this connector is specified inSection A.3 on Page 115. The RF connector is an MMCX female.Figure 10: OEM4-G2L Connector and Indicator Locations.Reference Description1 Power, data, and signal connector (24 pin dual row male connector with 0.5mm square pins and 2 mm spacing)2 LED status indicator3 RF signal input and LNA power output (MMCX female connector)4 External oscillator input (MMCX female connector)1243
