4.1 RCM3209/RCM3229 Digital Inputs and Outputs
The RCM3209/RCM3229 has 52 parallel I/O lines grouped in seven 8-bit ports available
on headers J1 and J2. The 44 bidirectional I/O lines are located on pins PA0–PA7, PB0,
PB2–PB7, PD2–PD7, PE0–PE1, PE3–PE7, PF0–PF7, and PG0–PG7.
Figure 6 shows the RCM3209/RCM3229 pinouts for headers J61 and J62.

The pinouts for the RCM3000, RCM3100, RCM3209, RCM3309, and RCM3900 are compatible.

Ethernet jack is also included on the RCM3209.
Pins 29–32 on header J61 are configured using 0 Ω resistors at locations JP9, JP10, JP7,
and JP8 to enable connections to PD2, PD3, PD6, and PD7 respectively. They may also be
reconfigured to carry the Ethernet signals TPO+, TPO–, TPI+, and TPI–, but this capabil-
ity is reserved for future use.
Pins 33 and 34 on header J61 are wired via 0 Ω surface-mount resistors at JP2 and JP3 to
carry the
and
ACT
LINK
module. These pins may be "configured" to carry PD0 and PD1, an option that is reserved
for future use.
See Appendix A.5 for more information about the locations of these headers.
