8.1.1.1. TCP/IP Control Ports

The C3-001 offers a dynamic range of available TCP/IP ports that

may be user-defined. The maximum amount of ports that can be

set is 15. The factory default active ports are 7145, 7147, 7149,

7151, and 7153.

8.1.1.1.1. Changing the TCP/IP Ports

Use the following command sequences to define the port settings:

POL? This query returns 15 comma delimited numbers

representing the available TCP/IP ports. Ports that

are not defined are zero.

POA NNNN This command adds a defined port number where

NNNN equals a number from 1 – 9999. Preceding

zeroes are not required for port numbers less than

1000.

POD NNNN This command deletes a specified port number.

The standard Telnet port 23 is also available but is reserved for

diagnostics and as a last-chance port for initiating an IP stack reset

(FORceclose).

8.1.1.2. Default IP Address

When a unit leaves the factory it is configured in DHCP mode.

When powered on, the CPU will send a broadcast request. If

available, a DHCP server will automatically assign an IP address to

the CPU as defined in the user network. In absence of a DHCP

server, a Link Local address will be resolved per IETF RFC 3927

8.1.1.3. Changing the IP Address

The IP address and other Ethernet settings may be changed

through the system’s front panel (See Section 2.11.2.1.1) or by

using the GET?/SET values 41-48, 53-56 (See Section 5.2.3).
