How To: Configure Summagraphics Summsketch Professional 4-button digitizer

Procedure

Summary

Steps to configure a 4-button Summagraphics Summasketch Professional
digitizer.

Procedure

Digitizers with a 4-button puck require the use of the menu bar provided in the PC ARC/INFO TECHNICAL HARDWARE GUIDE booklet. Appendix B of the booklet has the directions on how to install the menu bar and a copy of 4 menu bars for you to use. Make sure that a copy of one of the menu bars is located as close to 0,0 (lower left corner of the digitizer) on the digitizer as you can get, then permanently tape the menu bar down to the digitizer.

Please ensure the DIP SWITCH settings are correct as per the PC ARC/INFO
TECHNICAL HARDWARE GUIDE booklet. The S1 dip switch bank should have switch 1 ON and all the other switches (2 thru 8) OFF.

Run CON-DIG at the Arc prompt like this:

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

If you examine the SSPRO digform in a text editor you will notice that the 4 button on the key pad has been mapped to the #9 response in PC ARC/INFO. Therefore, any time PC ARC/INFO asks for a response of #9 (for example: #9 is the EXIT button in ARCEDIT) you have two options: 1) just push the #4 button on the key pad or 2) push any button on the key pad as long as the cross hairs are in the #9 box in the menu bar. See Appendix A of the PC ARC/INFO TECHNICAL HARDWARE GUIDE for a description of the digform file.

The following steps will help you install/troubleshoot the digitizer:

1. Connect the digitizer to your PC. Make sure and note what serial port the cable is hooked to.

2. Use the KERMIT utility provided with PC ARC/INFO to test if the digitizer is communicating in ASCII mode or BINARY mode. See the Related Information section below.

3. If the digitizer is communicating in BINARY format, run the utility driver that comes with your Summagraphics Summasketch Professional to set it to ASCII mode:

MM /x        <---- where x equals the port number

SEND /x /m /o /Czaczr <----- where x equals the port number

To do this, run CON-DIG at the Arc prompt like this:

CON-DIG SSPRO x 9600 O 8 1
| | | | | |_ stop bits
| | | | |___ data bits
| | | |________ parity
| | |_____________ baud rate
| |_______________ port #
|_____________________ format file

4. If the digitizer is communicating in ASCII mode, run CON-DIG at the Arc prompt like this:

CON-DIG SSPRO x 9600 N 8 1
| | | | | |_ stop bits
| | | | |___ data bits
| | | |_____ parity
| | |__________ baud rate
| |____________ port #
|__________________ format file

5) Issue the DIGTEST command from the ARC prompt and ensure that the digitizer is communicating correctly with PC ARC/INFO.

When you are performing DIGTEST and the output to the screen is four digits instead of five, and the highest x,y values represent half the size of the board (push the key pad buttons at the corners of the digitizer), try adding the /j switch to the SEND command in step 3:

SEND /x /o /Czaczr /j       <----- where x equals the port number 


Note:
If you do not have the utility drivers for MM and SEND for the original Summagraphics Summasketch Professional Digitizer, contact your digitizer vendor. It seems the MM and SEND drivers may have only been available for the Summasketch Professional II and higher versions. The newer digitizer versions no longer use jumper switches and rely solely on the utility drivers to change settings.
