CAUTION: Be sure that there is only one BOOT-P server running. If your network has DHCP or BOOT-P running, it may automatically assign an IP address to the controller upon linking it to the network. In order to ensure that the IP address is correct, please contact your system administrator before connecting the controller to the Ethernet network.

The second method for setting an IP address is to send the IA command through the DMC-3425 main RS-232 port. The IP address you want to assign may be entered as a 4 byte number delimited by commas (industry standard uses periods) or a signed 32 bit number. (Ex. IA 124,51,29,31 or IA 2083724575) Type in BN to save the IP address to the controller's non-volatile memory.

NOTE: Galil strongly recommends that the IP address selected is not one that can be accessed across the Gateway. The Gateway is an application that controls communication between an internal network and the outside world.

The third level of Ethernet addressing is the UDP or TCP port number. The Galil controller does not require a specific port number. The port number is established by the client or master each time it connects to the controller.

Ethernet Handles

An Ethernet handle is a communication resource within a device. The DMC-3425 can have a maximum of 8 Ethernet handles open at any time. When using TCP/IP, each connection to a device, such as the host computer, requires an individual Ethernet handle. In UDP/IP, one handle may be used for all the masters, but each slave uses one. (Pings and ARP's do not occupy handles.) If all 8 handles are in use and a 9th master tries to connect, it will be sent a "reset packet" that generates the appropriate error in its windows application.

The TH command may be used to indicate which handles are currently connected to and which are currently free.

Global vs. Local Operation

Each DMC-3425 controls two axes of motion, referred to as A and B. The host computer can communicate directly with any DMC-3425 using an Ethernet or RS-232 connection. When the host computer is directly communicating with any DMC-3425, all commands refer to the first two axes as A and B. Direct communication with the DMC-3425 is known as LOCAL OPERATION.

The concept of Local and Global Operation also applies to application programming. See Chapter 7: Global vs. Local Programming.
