How To: Configure the Summagraphics Summagrid III, 16-button digitizer

Procedure

Summary

Steps to configure a Sumagraphics Summagrid III, 16-button digitizer.

Procedure

1. Set your dip-switches to emulate the Calcomp 9100 format:

   9600
8 data bits
No parity
1 stop bit
Point mode
ASCII format
ACSII inches
No decimal
CR only
1000 lpi

The 'ON or 1' and 'OFF or O' dip-switch settings on the Summagrid IV can be confusing. The dip-switch is 'ON or 1' when the switch is towards the numbers. The dip-switch is 'OFF or O' when the switch is towards the OPEN label.

Switch A:
1 2 3 4 5 6 7 8
on off off X off off on on

- 1 9600 baud
- 2 9600 baud
- 3 9600 baud
- 4 don't care
- 5 no parity
- 6 1 stop bit
- 7 8 data bits
- 8 ASCII format

Switch B:
1 2 3 4 5 6 7 8
off off off off off on on off

- 1 ASCII inches
- 2 no decimal
- 3 CR only
- 4 inches
- 5 1000 lpi/ 40 lpmm
- 6 1000 lpi/ 40 lmpp
- 7 calcomp 9100 format emulation
- 8 calcomp 9100 format emulation

Switch C:
1 2 3 4 5 6 7 8
on off off off off ? ? ?

- 1 point mode
- 2 point mode
- 3 echo off
- 4 transmit only when in proximity
- 5 beeper disabled
- 6 application dependent <-- 6 indicates the digitizer's size
- 7 application dependent <-- 7 indicates the digitizer's size
- 8 application dependent <-- 8 indicates the digitizer's size

The appropriate digitizer board size settings for Switch Bank C, dip-switches 6, 7 and 8 are:

dip-switch    6    7    8
----------------------------------
18" x 24" on on off
36" x 48" on off off
24" x 36" off on off
44" x 60" off off off

2. Create the following digform format file with an ASCII editor (e.g. DOS Edit, NOTEPAD, WORDPAD):

'SGRID3'                    		Summagraphics Summagrid III 
1 Digitizer device #
'(A3,2F5.3)' Digitizer format
F No menu bar
F Single button mode off
73.0, 1.0, 0.0 X max, x scale, x offset
85.0, 1.0, 0.0 Y max, y scale, y offset
12
'APD' 0, 'AP0' 1, 'AP1' 2, 'AP2' 3, 'AP4' 4, 'AP5' 5,
'AP6' 6, 'AP8' 7, 'AP9' 8, 'APA' 9, 'APC' 10, 'APE' 12
-1

3. Save the file as SGRID3 and place it in the C:\ARCEXE\DIGFORMsub-directory.

4. Run CON-DIG at the Arc prompt like this:

CON-DIG SGRID3 x 9600 NONE 8 1
| | | | | |_ stop bits
| | | | |___ data bits
| | | |________ parity
| | |_____________ baud rate
| |_______________ port #
|______________________ format file

5. Run DIGTEST (for DOS) or DIGTESTW (for Windows Extensions) utility to ensure the digitizer is configured correctly.

Note:
This digitizer is only supported in the POINT MODE of operation. STREAM MODE of operation is not supported.

A sample of the correct RAW DATA that can be obtained in KERMIT or the 1st test in DIGTEST or DIGTESTW is:

AP00123401567  <-- for pushing the '1' button on the puck
APC1000218213 <-- for pushing the 'A' button on the puck
