2: Introduction Device Port Interfaces RS-232 RJ45 Interface All devices attached to the RJ45 device ports must support the RS-232C (EIA-232) standard. For serial RJ45 device ports, RJ45 cabling (e.g., category 5 or 6 patch cabling) is used. Serial RJ45 device ports for the EMG are reversed by default so that straight-through RJ45 patch cables may be used to connect to Cisco and Sun RJ45 serial console ports. See Table 2-9. The serial RJ45 ports have software reversible pinouts to switch between DTE and DCE applications. The serial RJ45 ports match the RJ45 pinouts of the console ports of many popular devices found in a network environment, and where different can be converted using Lantronix adapters. The RJ45 ports have software reversible pinouts to switch between digital terminal equipment (DTE) and digital communications equipment (DCE) applications. RJ45 to DB9/DB25 adapters are available from Lantronix. For serial pinout information, see Appendix C: Adapters and Pinouts on page 477.
