I/O STROBE PORT CABLE
The I/O strobe lines can be accessed by inserting the 8-pin LEMO connector of the I/O strobe port cable (NovAtel p/n
01016330) into the I/O port. Figure 8 and Table 4 contain wiring and pin-out information on this cable. The other end of
the cable is provided without a connector so that the user can provide an application-specific one; the jacket insulation is
cut away slightly from the end but the insulation on each wire is intact. The Input/Output Strobes section of Appendix A
contains a specification of each I/O strobe signal.
For field replacement of the LEMO connector, please consult Appendix B for the manufacturer’s part number.
