Driver instructions for Summagraphics
Summagrid 3 and Summagrid LCL
The Logic Group digitizing software can be
used with or without the windows wintab driver, other vender software
will generally require the windows driver. The digitizer can be used
connected to the computer with either the serial port or usb port (using
a serial to usb adapter from radio shack). A digitizing tablet manual is
not needed to use the digitizer but one is available for download from
the www.gtcocalcomp website.
Installation using the wintab driver
See Wintab Installation Wizard
Installation without the wintab driver:
1. If using the serial to usb adapter, attach the usb adapter to the
computer first and install the serial to usb driver that came with the
adapter (the cd is in the back packaging of the adapter). After
installing make sure the com port is set from com1 to com4.
2. The switch settings are preset by The Logic Group and should be set
at Switch A 1,4,5,6 on, Switch B 6 on, Switch C 1,6 on (for a 36x48
digitizer)
3. Attach the pointer to the digitizer, the serial cable to the
digitizer and to the computer (or the serial to usb adapter), the power
supply to the digitizer and wall output, turn the digitizer on, the
tablet should beep and green light come on.
4. Install The Logic Group digitizing software, start the program, click
digitize new, click setup tablet setup, change driver from "wintab any
manufacturer" to "Generic Tablet Driver", choose the size, choose the
serial port, click install, click show driver, make the following
changes:
Baud Rate 9600, parity even, data bits 7, stops bits 2, point mode
.027M1, track mode .027M2, other commands blank, use any button to
digitize, 8 bytes, 1000 resolution, binary output, no echo

Press Ok, click text xy, digitize a point on the tablet, result should
be x=xxxxx,y=yyyyy.
5. If using the serial to usb adapter occasionally windows will change
the com port. If the wintab driver cannot find the tablet, check the
serial to usb com port.
