8. HEADERS
The RMB-167i board has three headers: the input/output header JP9 and the system
header JP8 and the extra input/output header JP10. Ports 2, 3, and 5 are available on
JP9. JP8 contains the address, data and control busses. Individual signals of these
jumpers are listed below. The tables reflect the physical orientation of the headers and the
enumeration of their individual posts. Pin 1 may be identified as the post with the square
pad on the printed circuit board.
