64. Page 11 AVT 85x Multiple Interface In this mode the AVT 853 XPort will on power up search for a DHCP server If one is found it will obtain its IP address gateway address and subnet mask from the DHCP server If a DHCP server is not found the AVT 853 XPort will then switch to AutoIP addressing described in the next Section An AVT 853 IP address of 0 0 1 0 enables DHCP addressing and disables AutoIP addressing 4 2 3 AutoIP Addressing AutolP is an alternative to DHCP that allows hosts to automatically obtain an IP address in smaller networks that may not have a DHCP server Quoted from Lantronix XPort User Manual revision A 3 03 page 3 4 AutoIP addressing is only enabled if the AVT 853 XPort IP address is set to 0 0 0 0 and no DHCP server is found If on power up the AVT 853 XPort cannot find a DHCP server it will automatically assign itself an AutoIP address range 169 254 0 1 to 169 254 255 1 It will then send out an ARP Address Resolution Protocol request onto the network to see if any other node already has that address If no conflict is found the AVT 853 XPort will use that address until the next power on reset or reboot If an address conflict is found another node is discovered to already have that address then the AVT 853 XPort will select another AutoIP address send out another ARP request The process will continue until it finds an address that is not being used 4 3 Packet Communications with Host Co

67. The alternate transmit command formats 11 xx and 12 xx yy are available and will work After the host sends complete transmit command the AVT 85x will perform the following e Check the command e Store the data e Determine if the transmit operation requires a single frame or multiple frames e Compute the required PCI byte and insert it into the data field e Compose the frame or frames including the PCI byte and AE byte if enabled e Pad the data field of the frame if enabled e Wait for and decode the received flow control frame if necessary e Send one transmit ack to the host if enabled when the entire transaction is complete The user should OMIT all PCI byte s from the transmit command OMIT all pad byte s from the transmit command If AE Address Extension is used for a particular application and module then include the AE byte just once in the correct place of several commands and enable AE support for the CAN channel being used 7 13 8 1 Pacing Note 2 When transmitting a multi frame message the AVT 85x will attempt to use the separation time specified in the flow control frame received from the downstream module If the downstream module responds with a flow control separation time of 00 the AVT 85x will transmit frames as fast as it can It is possible an AVT 85x can transmit frames too quickly The 7x 35 pacing command will insert a programmable delay between transmitted frames This delay will only be
