NOTE: This information applies to serial installations only.
Introduction to the Custom Configuration Menu
The Custom Configuration Menu is used to relay configuration information to the Roll-Up III
in those cases where Table 1 and Table 2 do not supply the information or a SuperSet
Menu Code for the graphic application software being used. You will use the Custom
Configuration Menu to configure the Roll-Up III for a specific baud rate, data format and
other operating characteristics that your software requires for communication with the
digitizer. The Custom Configuration Menu is located in the slot at the end of the Roll-Up III
housing.
The configuration parameters for Roll-Up III are divided into three categories:
 Communication Options
 Output Format Options
 Mode Options
Communication Options
 Baud: The rate, in bits/second, at which characters are transmitted across the RS-
232C serial interface. Choices are: 1200, 2400, 4800, 9600, 19200 or 38400.
 Data Bits: Data bits represent the actual data being sent from one device to
another. Both devices must be set for the same number of data bits. Choices are:
Seven (7) or Eight (8).
 Stop Bits: Each character has one or two stop bits, which tell the receiving device
that a character is complete. The number of stop bits usually does not matter.
Setting for two stop bits instead of one may overcome a mismatch in parity or data
bits. Choices are: One (1) or Two (2).
 Parity: One bit can be allocated for parity (parity is a simple error-detecting
scheme). Both devices (sending and receiving) must be set for the same parity –
either odd parity or even parity – or they must be set for no parity. Choices are:
None (N), Even (E) or Odd (O).
