• Several special keys on the RF Terminal keypad can generate a response automatically, sending a
separate message to the host by simply pressing the appropriate control key (without pressing the
ENTER key afterward). This allows for simple and fast scrolling by the operator. The arrow keys,
Begin, End, and Search are the specific keys supported. The default setting is to require the ENTER key
to be pressed before data transmission.
• If you set this feature to ON, in order for the RF Terminal to transmit the following values, the
corresponding Control Key must be the first key pressed in a data entry sequence. If it is not the first
data entered, the arrow key is ignored.
Control Key on RF Terminal Code transmitted to Host
Up Arrow FS (ASCII 28)
Down Arrow GS (ASCII 29)
Left Arrow RS (ASCII 30)
Right Arrow US (ASCII 31)
Begin ETB (ASCII 23)
End CAN (ASCII 24)
Search VT (ASCII 11)
The message is sent to the host as:
Bytes Function Value
1 RF Terminal ID 0-9, A-Z, a-z, - =
2 Data Transmitted ASCII Value from Table Above
Last Terminator of Message CR
Automatic Check Back
This parameter should not be changed under normal circumstances. After the host sends a prompt, the
Terminal goes to sleep waiting on the operator to key or scan input in response to the prompt. It waits until
the Automatic Shut Off time or until the operator responds. This parameter sets the time that the Terminal
stops waiting on input from the operator, discards the current prompt, and goes back to the host to see if
there is a change in instructions. If no change, the host must resend the prompt again because the Terminal
has discarded the original prompt. The host now has the opportunity to change a prompt. The time can be set
in increments of 5 seconds, up to 495 seconds. The default value is 00. The values possible for entry are 00-
99. An entered 99 gives 99x5 seconds, or 495 seconds between check backs. The Terminal sends back an
ASCII 07 for the data back to the host (ID ASCII 07 CR). To change this value press the 6 key in the RF
Configuration menu and enter the 2 digit value desired.
Bar Code Options
Code 3 of 9 (Code 39)
Code 3 of 9 ON OFF 1
Full ASCII ON OFF 2
Accumulate Mode ON OFF 3
Transmit Start Stop ON OFF 4
MOD 43 Check Digit ON OFF 5
Transmit MOD 43 ON OFF 6
Caps Lock ON OFF 7
Decode Option 0, 1, 2 8
• The Start and Stop character for Code 39 is the * character. Setting 4 determines whether or not those
characters are transmitted to the computer along with the data. For example, at setting ON, the data of
1234 would be transmitted as *1234*. Transmitting the start and stop characters can be useful if you
need to differentiate between data that comes from a bar code versus data coming from the keypad.
