Ethernet Connector
Figure C-1. RJ45 Ethernet Connector
RJ45 Serial Connectors
ETS servers are RS-423 compliant, and are thus limited by the equipment at the
remote end of the serial line. If the port is connected to an RS-232 device, it is
subject to RS-232 limits: 15m (50 ft.) in length at 9600 baud, and to 2m (6 ft.) at
115.2K baud, although longer lengths will generally work.

RJ45 to DB25
If you are connecting an RJ45 port to a DTE device (such as a terminal) that has a
DB25 connector, you will need to use an RJ45-DTE DB25 adapter. To connect an
RJ45 port to a DB25 connector on a DCE device, you will need an RJ45-DCE DB25
adapter. The pinout information for both connections is shown in Figure C-3.
