RS232 Port D
Five screw terminals (for TD, RD, RTS, CTS, and GND) are provided to make your connections.
Ethernet Port 1 (Primary)
This port is found on all units. It is a 10/100BaseTx auto-detecting and auto-crossover Ethernet port. This means it will
auto-detect the speed, and work with either a straight-thru or cross-wired Ethernet cable. A standard shielded RJ45
connector is provided. See the figures below for the pin-outs. This port has a fixed unique MAC address. The IP address
can be set with the Sixnet I/O Tool Kit software. Refer to the online help for details.
Ethernet Port 2 with Built-in Switch
This port is found on only the SixTRAK IPm RTU/Controller. It is internally tied to an industrial Ethernet switch. This
provides four switched ports (standard shielded RJ45 connectors) to connect to peripheral equipment such as Red Lion’s
EtherTRAK-2 I/O modules. All are 10/100BaseTx auto-detecting and auto-crossover Ethernet ports. This means they will
auto-detect the speed, and work with either a straight-thru or cross-wired Ethernet cable. This port has a fixed unique MAC
address. The IP address can be set with the Sixnet I/O Tool Kit software. Refer to the online help for details.
Note:
The primary Ethernet port is not internally tied to the internal Ethernet switch or the second Ethernet port.
The first and second Ethernet ports act independently from each other. Refer to the Red Lion Electronic Help
system for more details and usage tips.
