PCIE8LXMCX2CB RESISTOR SELECTION CONNECTOR
IO0 refers to XMC 0 and IO1 refers to XMC1. Resistors are numbered with the “R”
implied (not shown in table). With the RP [Jn4] and/or RX[Jn6] resistors installed the
respective connectors are tied into the IO selection matrix.
Example(1) installing R474 and R475 will tie the J04 IO0_31 differential pair to the IO
Selection point. Adding R219 and R218 will connect through to the IO connector [SCSI
or DIN].
Example(2) installing R538 and R539 will tie the J06 IO0_31 differential pair to the IO
Selection point. Adding R346 and R347 will connect through to the CB bus. The
corresponding R’s will need to be installed to tie to J14 or J16.
