1 Byte
1-255
***** Pk Num MUST be at least 1 count different between packets (1,2,1,2 or 1,2,3,4,5)
1.
This will send the following data from the LOCAL DR2000 Address 32 TO the
REMOTE DR2000 address 31. The REMOTE display will print
“ABCDEFGHIJKLMNOPQRSTUVWXYZ1”.

This will send the following data from the REMOTE DR2000 Address 31 TO the
LOCAL DR2000 address 32. The LOCAL display will print
“ABCDEFGHIJKLMNOPQRSTUVWXYZ1”.
Note1:
Enter the following commands on the LOCAL DR2000:
Enter the following commands on the REMOTE DR2000:
Send the following from the LOCAL DR2000:
