Galil DMC-2X00 user manual Addressing, Led

	Although UDP/IP is more efficient and simple, Galil recommends using the TCP/IP protocol. TCP/IP
	insures that if a packet is lost or destroyed while in transit, it will be resent.
	Ethernet communication transfers information in ‘packets’. The packets must be limited to 470 data
	bytes or less. Larger packets could cause the controller to lose communication.
	NOTE: In order not to lose information in transit, Galil recommends that the user wait for an
	acknowledgement of receipt of a packet before sending the next packet.
	There are four LEDs provided for the status of Ethernet connection. The representation of LED status
	is given below.
LED	Status
F	Uses Fiber Link

CUses Full Duplex – will blink when a collision Uses Full Duplex – will blink when a collision occurs with half duplex

L	Ethernet link established – will blink for any activity
100	Uses 100Base T speed Ethernet

Addressing

There are three levels of addresses that define Ethernet devices. The first is the Ethernet or hardware address. This is a unique and permanent 6 byte number. No other device will have the same Ethernet address. The DMC-2100/2200 Ethernet address is set by the factory and the last two bytes of the address are the serial number of the controller.

The second level of addressing is the IP address. This is a 32-bit (or 4 byte) number. The IP address is constrained by each local network and must be assigned locally. Assigning an IP address to the controller can be done in a number of ways.

The first method is to use the BOOT-P utility via the Ethernet connection (the DMC-2100/2200 must be connected to network and powered). For a brief explanation of BOOT-P, see the section: Third Party Software. Either a BOOT-P server on the internal network or the Galil terminal software may be used. To use the Galil BOOT-P utility, select the registry in the terminal emulator. Select the DMC- 2100/2200 and then the Ethernet Parameters tab. Enter the IP address at the prompt and select either TCP/IP or UDP/IP as the protocol. When done, click on the ASSIGN IP ADDRESS. The Galil Terminal Software will respond with a list of all controllers on the network that do not currently have IP addresses. The user selects the controller and the software will assign the controller the specified IP address. Then enter the terminal and type in BN to save the IP address to the controller's non-volatile memory.

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.
