7 Pin Assignment – I/O Connector
Connect channel I/O either to front I/O or P14 back I/O at a time. Do not connect an I/O channel
to both front I/O connector and P14 back I/O connector at the same time.
RS422 channels provide on board termination resistors. Do not apply additional external
termination resistors here.
Please note that on the TPMC462, the P14 back I/O connector is always populated and
connected to on board logic. Do not use these modules on carrier boards where P14/J14 is
reserved for other system signals but PMC I/O. In this case ask support for special board
options with front I/O only.
