TCP/IP Communications Setup Command Set
This section describes the commands recognized by the CubiScan 125 to set up the CubiScan 125
for communications with a network using the TCP/IP protocol.
You can use the Qbit, QbitTCP software to configure the CubiScan 125 for TCP/IP
communications. Contact Quantronix for information.
Configuration of the CubiScan 125 for TCP/IP communication is performed through the RS-232-
C serial communications port using the following commands.
Set Port
This command is used to set the CubiScan 125 TCP port number. In TCP/IP networks, port
numbers are used to distinguish between different logical channels on the same network
interface on the same computer. For example, port 80 is used for HTTP traffic on the Internet.
Some ports have numbers assigned to them by the Internet Assigned Numbers Authority (IANA).
These are known as “well-known ports” and are limited to numbers 0 through 1023. Ports 1024
through 49151 are “registered ports” listed by the IANA, and can be used by ordinary user
processes on most systems. Ports 49152 through 65535 are called “dynamic and/or private ports”
and are free for use. It is recommended that the CubiScan 125 TCP port be set to a number
