6-5
displays differ slightly from the “Clear lines” command for the current 6
line displays.
The following table shows the programming differences that started with
version 9075:
Command Prior to 9075 9075 and after
@C0 Command did not exist Clears all lines on both a 4
line display and a 6 line
display.
@C5 Cleared all lines on a 4 line
display
Clears line 5 on a 6 line
display. Clears ALL lines on
a 4 line display.
@C6 Command did not exist Clears line 6 on a 6 line
display. Will not affect a 4
line display
There are several other changes concerning the display in version 9075 and
after:
• In order to use 6 line display terminals as 6 line terminals in a existing
4 line system, the Base Station must have firmware version DLx9075
or greater. If you try to use a 6 line terminal in 6 line mode on a Base
Station with a version prior to DLx9075, the Base Station will send
back an erroneous message:
Base Reinitialized
Cycle Power on RF
Terminal and Sign-On
• 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. Prior to
9075, all terminals signed on using ASCII 15. As of 9075, 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, as do all terminals prior to version 9075. 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.
