Roll-Up II 38
Set Digitizing Rate Code: Rx
Coordinates can be sent from the Roll-Up II 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 Roll-Up 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 . Roll-Up II 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.
