Scott,

There is one gotcha when you use the ethernet communication. 

The IP address of the Compumotor is unknown to the PC.

Note: You set the controller IP address through the serial port communication.

Then you activate the ethernet port.

Next, you have to associate your host PC IP address with the target IP address of the controller.

To do this you have to create a batch file using the arp command:

Basically, you have to use: arp -s (target IP) (target hex address) (host IP)

for example:

arp -s 123.123.10.100 00-90-55-00-19-66 123.123.10.101

Note: The two IP addresses should be on the same subnet.

The following is the help for the arp command:

Displays and modifies the IP-to-Physical address translation tables used by
address resolution protocol (ARP).

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr]

 -a Displays current ARP entries by interrogating the current
 protocol data. If inet_addr is specified, the IP and Physical
 addresses for only the specified computer are displayed. If
 more than one network interface uses ARP, entries for each ARP
 table are displayed.
 -g Same as -a.
 inet_addr Specifies an internet address.
 -N if_addr Displays the ARP entries for the network interface specified
 by if_addr.
 -d Deletes the host specified by inet_addr.
 -s Adds the host and associates the Internet address inet_addr
 with the Physical address eth_addr. The Physical address is
 given as 6 hexadecimal bytes separated by hyphens. The entry
 is permanent.
 eth_addr Specifies a physical address.
 if_addr If present, this specifies the Internet address of the
 interface whose address translation table should be modified.
 If not present, the first applicable interface will be used.

Greetings fellow VEE'ers,

We want to connect to a 6K controller made by Compumotor over our network LAN connection. But we are having trouble getting VEE to recognize the connection. We are completely new to connecting over a LAN connection and any help we could get would be appreciated.
We are using Vee 5.1 on Win 2000.

The equipment we are trying to connect to can be found at site. http://www.compumotor.com or http://www.compumotor.com/catalog_2002/ ... ollers.pdf

Thanks,
