Part of the RS232 command will be an address. This address may take several forms.
For example, suppose you have eight displays in one area divided into two groups.
You might set the IDs of the displays like this:
With this scheme, you have four ways to address these displays:
ASCII Response Type
Determines what type of data will be returned to the computer. For human-readable
text in a serial program, choose SYMBOLIC. For computer-read data, use NUMERIC or
DATA ONLY.
ASCII Response Terminator
Will be determined by what your serial program wants to see at the end of every
transmission from the display.
Group ID Unit ID
A1
A2
A3
A4
B1
B2
B3
B4
Address Affect on Displays

B4
etc.
Only the specific display addressed will obey the command.
Also, the display will respond to the host computer.
** All displays in this serial loop will obey the command.
*4 Both the displays whose IDs end in “4” will obey this
command.
B* All four displays in Group B will obey the command.
