These are RJ45 connectors for connecting input/output units
such as the S-1608, S-0816, or S-4000S via Cat5e Ethernet cables.
These connectors support Cat5e Ethernet cables up to 100
meters long. If you need a longer connection, we recommend
that you use the optional S-OPT.
The default input/output patching between the M-300 and
input/output units connected to REAC ports A/B is as
