“Direct” TCP/IP
Connection
The term “Direct” used here should not be confused with the
“Direct IP” connection mode, which is a special case of
Internet connection to a static IP address. Here the term
“Direct” is used to describe a TCP/IP connection between a
receiver and a local computer through a special Ethernet
connection, using a crossover cable connected directly
between the receiver and the computer.
In a crossover cable, the pinout is inverted at one end of the
cable. The crossover cable is not provided but is widely
available from computer supply stores or online.
This type of connection is required when the receiver is not
otherwise using its Ethernet port and there is no network
connection available in the operating environment of the
receiver (machine control, machine guidance).
In this case, make the following settings BEFORE physically
connecting the computer to the receiver through the
crossover cable:
• On the receiver, disable the DHCP mode and define an
arbitrary static IP address and a subnetwork mask for the
receiver.
• On the computer, change the network configuration for an
exclusive TCP/IP connection with the receiver.
Before changing the network configuration of the
computer, it is advisable to write down all the current
settings so that you can easily reverse to the previous
network configuration when you are done with
communicating with the receiver.
1. Send the following command to the receiver to read the
current settings. Write them all down so that later you can
easily reverse to these settings.
NOTE: It is assumed that the reader knows how to send
$PASH commands to the receiver through a serial line or
