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 systems 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).
