In the Ethernet Networking Documentation for the 6K, some details of the DVT connection are left out. Below, is the rest of the necessary information to setup these devices to communicate.
First of all, the 6K connects to port 5001 on the DVT camera, which is the DATALINK response port. This port only allows the 6K to send an external trigger and get back information. So the typical application for the DVT and 6K is as follows; first a trigger event happens at the DVT camera. This event happens based on an external voltage change on the DVT I/O, from a NTWRIT command from the 6K or a predetermined condition internal to the DVT camera, which will evaluate a part. Then the DVT will respond to the 6K with information for the application.
The information that can be passed from the DVT Camera to the 6K is strictly real variables (VAR's). All real variable can be used (1-225), but no other information (like VARI's, VARB's, DRIVE, etc.) will be recognized from the DVT camera. Multiple variables can be changed at one time, but they must be separated by a delimiter. The only delimiter supported is a comma. This comma must be after every 6K variable change, like below.
There must be a comma at the end of the statement!
An exclamation mark (!) before commands is not needed and not recommended.
The NTWRIT command, which writes a trigger to the DVT camera from the 6K, already includes a carriage return and a line feed for end of transmission character. On the 6K, the "\" command does not work with the NTWRIT command.
