Worth Data 701 RF manual Base Station to Host Formats, Serial Reply, 2123+CR

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

Base Station to Host Formats

The basic format of a message that is transmitted from Base to Host is fairly simple:

Byte position	Function
1	RF Terminal ID
2+	Data Transmitted
Last	Termination of message

Possible values

0-9, A-Z, a-z, - =

**

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

Where 2 is the Terminal ID, 123 is the data and CR is the termination, (the plus sign is not transmitted).

Besides data, there are other messages that the Base Station will send to the Host:

Serial Reply

After a Serial command (@S) has been successfully completed, the Base Station sends to the Host the Terminal ID followed by a CR. Serial
