To open the Device Ports - Settings page:
1. You have two options:
Starting Telnet Port
Each port is assigned a number for connecting via Telnet. Enter a number (1025-
65528) that represents the first port. The default is 2000 plus the port number. For
example, if you enter 2001, port 1 will be 2001 and subsequent 2000 ports are
automatically assigned numbers 2001, 2002, and so on.
Starting SSH Port
Each port is assigned a number for connecting via SSH. Enter a number (1025-
65528) that represents the first port. The default is 3000 plus the port number. For
example, if you enter 3001, port 1 will be 3001 and subsequent 3000 ports are
automatically assigned numbers 3001, 3002, and so on.
Starting TCP Port
Each port is assigned a number for connecting through a raw TCP connection. Enter
a number (1025-65528) that represents the first port. The default is 4000 plus the
port number. For example, if you enter 4001, port 1 will be 4001 and subsequent
4000 ports are automatically assigned numbers 4001, 4002, and so on.
You can use a raw TCP connection in situations where a TCP/IP connection is to
communicate with a serial device. For example, you can connect a serial printer to a
device port and use a raw TCP connection to send print jobs to the printer over the
network.
Note:
When using raw TCP connections to transmit binary data, or where the break
command (escape sequence) is not required, set the Break Sequence of the
respective device port to null (clear it).
