•The “Clear lines” command (@Cx) for the 4 line displays differ slightly from the “Clear lines” command for the current 6 line displays.

• The following table shows the programming differences for 4 lines/6 lines:

Command	4 Line	6 Line	15 Line
@C0	Clears all lines	Clears all lines	Clears all lines
@C5	Clears all lines	Clears line 5	Clears line 5
@C6	No effect	Clears line 6	Clears line 6
@CA	No effect	No effect	Clears line 10

•In order to maintain compatibility with 4 line display terminals in an existing system, there is a new option in the RF Terminal Setup for 6 line display terminals. The LCD DISPLAY MODE allows the user to configure a 6 line display terminal as a 4 line display (centering the data on the display and conforming to the old programming command format, i.e. @C05 clears all lines). See Installation and Setup for details on how to get into LCD DISPLAY MODE.

•The SIGN ON character for a 6 line display RF Terminal operating in 6 line display mode (see the previous point concerning LCD DISPLAY MODE) is different than for a 4 line display. A 6 line display terminal operating in 6 line mode signs on using ASCII 22. If the 6 line terminal is configured for 4 line display, it signs on using ASCII 15. This allows you to use both types of display in the same system and be able to distinguish between the two terminal types. See page 6-6 for more information on SIGN ON.

CAUTION: All 6 line display terminals are by default, configured as 6 line display terminals and will try to SIGN ON using ASCII 22. If you are trying to SIGN ON to an existing 4 line display terminal system that has not had any changes in its programming to utilize the 6 line display terminals, the 6 line display terminal will NOT BE ABLE TO SIGN ON. Make sure to reconfigure the Terminal using the LCD DISPLAY MODE to operate as a 4 line display terminal.

Here are some sample command statements utilizing some of the programming tips offered above:

@2,1,1,ENTER ITEM NO	Display ENTER ITEM NO on line 2, position 1
	and wait for wait for data input. This is a valid
	single command statement – it ends with a
	data entry request.
@V23@1,2,1,WRONG ITEM	Play voice message 23, display WRONG ITEM
	on line1, position 2 and wait for data input. This is
	a valid multiple command statement – it ends
	with a data entry request.
@C1@1,7,0,PICKING	Clear line 1. Display PICKING at position 7 of
	line 1. This statement is illegal. To be a valid
	statement, it must end with a data entry
	request. For example:
	@C1@1,7,0,PICKING@2,7,1,ITEM
@1,1,1,ITEM@2,1,1,QTY	Since only one command can be a “prompt” data
	entry request, this is an illegal statement and
	would be ignored as a command. It would be
	valid if changed to @1,1,0,ITEM@2,1,1,QTY
