AccuTab II 35
Send Coordinates 0,0 When Transducer is Out of Active Area
No Output When Transducer is Out of Active Area Code: OP
Code: IP
Certain situations require that the AccuTab II be able to send a coordinate when the
transducer is out of the active area. Command OP permits coordinates to be sent under
this condition. Since valid coordinates are not available when the transducer is out of the
active area, coordinates 0,0 are substituted in the format. When this command has been
executed, digitizing modes operate normally, whether the transducer is in the active area
or not. Command IP returns AccuTab II to the default condition, in which coordinates are
sent only when the transducer is in the active area.
Set Digitizing Rate Code: Rx
Coordinates can be sent from AccuTab II at rates from 5 to 100 coordinates per second.
The second character in this command sets the rate, as shown in the table below. Actual
rates are limited by the communication baud rate and coordinate type you have selected.
The rates shown here are, therefore, maximum rates.

Change Mode Character Code: MC
Some applications may have a predefined meaning for the SOH (CTRL-A) character used to
invoke Command Mode. If so, invoking Command Mode may cause your system to do
something else. You can set the AccuTab II so that a character other than SOH is used to
begin Command Mode. Here is how to make the substitution:
1. Enter Command Mode.
2. Send MC, followed by a <CR>. Super L III responds with the prompt message:
ENTER NEW COMMAND MODE CHARACTER:
3. Enter the desired mode change character. The new mode character can be any
character except ESC (CTRL-[, hex 1B), <CR> (CTRL-M, hex 0D), CAN (CTRL-X, hex 18),
VT (CTRL-K, hex 0B), XON (CTRL-Q, hex 11) or XOFF (CTRL-S, hex 13).
Now, when you want to enter the Command Mode, send the new character. All other
command operations remain unchanged.
