User's Manual

6-6
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 re-configure the Terminal using
the LCD DISPLAY MODE to operate as a 4 line display terminal.
• 4 line display terminals can be upgraded to 6 line display terminals for
$150.00 per terminal. Call us for an RMA number, as the terminals must
come back to us for the upgrade.
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
@V23@1,2,1,WRONG
ITEM
Play voice message 23, display WRONG ITEM on
line1, position 2 and wait for data input
@C1@1,7,0,PICKING Clear line 1. Display PICKING at position 7 of line
1. This command by itself 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.
Base Station to Host Formats
The basic format of a message that is transmitted from Base to Host is fairly
simple:
Byte position Function Possible values
1 RF Terminal ID 0-F
2+ Data Transmitted **
Last Termination of message CR (ASCII 13)
Typically, the Base Station is sending the “answer” to the hosts “question” - for
example, if a Base sent a host message to a terminal #2 that said:
2@1,1,1,ITEM NUMBER + EOT
The RF Terminal would display ITEM NUMBER on line 1, position 1 and
accordingly, the operator would then enter an item number by scanning or using
the keypad. The RF Terminal transmits the data entered -say it’s 123 - to the
Base Station, which in turn transmits the following to the host:
2123+CR
