User's Manual

 Messages can be a combination of multiple commands, (i.e. voice

messages, initialization, clearing lines, requesting data entry), up to

231 characters in length. A message cannot though, contain an @S

command in combination with any other command. A message

also should not contain more than 1 request for data entry (third

character in command is 1). For example:

@1,1,1,ITEM@2,1,1,QTY

has two data entry “prompt” commands combined. If this message

were sent to the RF Terminal, the first data entry prompt

(@1,1,1,ITEM) would be executed, but any and all commands after

the first data entry prompt in that statement would be ignored

without warning – there will be no display or indication of an illegal

command.

The @S command (for serial output) statement cannot be

combined with any other command - even clear (@Cx)

commands. After a @S command is successfully completed,

the Base Station sends back to the host the RF Terminal ID

followed by a CR (ASCII 13). There is a 231 character limit

on data for this command. If you send a command of more

than 231 characters, you will get an Illegal Command

returned, (ID ? CR). If you need to send 300 characters of

data, send the first part, wait for the acknowledgement (ID

CR), and then send the remaining part. If you are using the

@S command with a printer other than the Zebra Cameo or

QL3, you may have to change the Protocol parameter in the

RF Terminal to XON/XOFF. This will allow the RF

Terminal to deal with the character buffer limitations of your

particular printer. If you are using the O’Neil MicroFlash

Printer, you must send a NULL character before the valid data

to wake up the printer. See your printer manual for details and

see Chapter 6 for details on printer protocol.

 The @M command is similar to the @S command, except it can

be combined with other commands because it is a data entry

command too. This command is for a printer initialization and

magstripe input on the Zebra Cameo printer equipped with the

magstripe option. The format of the command is:

@Mdddatttta(EOT)

where dddatttta might be ! U1 MCR 80 T1 T2+ CR + LF

(Refer to the Cameo manual for the exact string sequence you

need to send. The above example sends over an 10 second

request for reading Track 1 and Track 2).
