RJ45

This section defines the pinouts for the RJ45 connection (see RJ45 SCS48C/SCS32C/SCS16C/SCS8C on page 354 for the SCS48C model). 1-port, 2-port, and 4-port desktop IOLAN models have a 10-pin RJ45 connector and all rack mount IOLAN models have an 8-pin RJ45 connector. These pinouts do not apply to I/O models.
