When the LDT configuration data has been acknowledged for LDT 1, the program will copy
the configuration data for LDT 2 into the output image table. The speed of wire is defined as
9.272µs/inch. The counts will be increasing from the LDT head. There is one recirculation in the
LDT and the LDT length is 24.0 inches. This will continue until the command is acknowledged
by the 1746L LDT Interface Module.
