The Roll-Up III
24
Introduction to the
Custom Configuration Menu
The Custom Configuration Menu is used to relay configuration informa-
tion to the Roll-Up III in those cases where Table 1 and Table 2 do not
supply that information or a SuperSet Menu Code for the graphic applica-
tion software you are using. 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 the 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 RS232C 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).
Output Format Options
GTCO
Selects GTCO-compatible formats. See Advanced Program-
ming Information in the Roll-Up III Online Help for greater detail on
GTCO format structure. Choices are: Binary, or ASCII.
