Cordless Roll-Up 41
Set Digitizing Rate Code: Rx
Coordinates can be sent from the Cordless Roll-Up at rates from 5 to 140 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 Cordless Roll-Up 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 . Cordless Roll-Up 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), (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.

Measurement Scales for additional information on how scale selection affects coordinate
data.
Enable Echo Mode
