RCA RMB-167 Headers and Jumpers, System and I / O Headers, JP6 System Header Signal, 166 JP1 JP6

7 HEADERS AND JUMPERS

7.1System and I / O Headers

The RMB-167 board has three headers, two of which are compatible with those of the RMB-166. The two RMB-166 headers, the input output port header JP2 and the system header JP1, are similar to the headers JP6 and JP7 of the RMB-167. In addition, the RMB-167 has JP8, the Extra Input/Output header XIO. Ports 2, 3, and 5 are available on JP7. JP6 contains the address, data and control busses. JP8 contains the additional ports and signals of the SAB-C167 microcontroller. 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 is identified as the post with the square pad on the circuit board.
