Installing a Calcomp Digitizer

This file details how to set up the hardware for a Calcomp 9100 series digitizer. The cabling and switching settings are suggestions only. A different Masscomp or Sun may need a different cable configuration.

NOTE: That the table size has to be set by the SB1 dip switches. Consult your Calcomp manual for your particular table settings.

WARNING: These switch settings and cable configurations are for Port A/C. There is information about Port B/D mentioned later in this file.

Switch Settings

    ---------------

There are two banks of eight switches (SW1 and SW2) on the Communication Interface Board. There is one bank of eight switches (SB1) on the Digitizing Processor.

Switch settings:

## SW1

    	---

1 - closed
2 - closed parity disabled
3 - closed
4 - closed 1 stop parity
5 - open 8 data bits
6 - closed
7 - closed 9600 baud
8 - open

## SW2

    	---

1 - open port B/D on
2 - open
3 - closed LF port A/C off
4 - open Port A/C on
5 - closed menu off
6 - open cursor on
7 - closed echo off
8 - closed LF port B/D on

## SB1

    	---

1 - open
2 - open operating mode (run)
3 - closed
4 - open output format 2
5 - closed
6 - close resolution 1000 LPI
7 - open
8 - close 91480, 36 X 48 inches (table size)

Cabling

    -------

The cabling between the digitizer and the computer differ for different computers. Some known cable configurations for port A/C:

## SUN 3/110:

Sun Calcomp

    	 2  ----  3

    	 3  ----  2

    	 4  ----  4

    	 5  ----  5

    	 7  ----  7

    	 20 ----  20

    -------------------------------------------------------

What follows is a description if you want to use Port B/D instead of Port A/C. Port B/D does echoing of commands. Make sure the echoing of port B/D is off by with the dip switches (SW2-7 closed). Turn off LF on port B/D (SW2-8 closed).

Some known cable configurations for port A/C:

SUN 386i:

Sun Calcomp

    	 2  ----  2

    	 3  ----  3

    	 7  ----  7

There should be no 4 or it will not work.

    -------------------------------------------------------

If the v.digit program isn't working, make sure the tty the digitizer is on has the getty off, the tty permissions are set to 'crw-rw-rw', the 'digitcap' file is correct for your system configuration, and the switch settings on the digitizer are correct. There are some diagnostic programs under $GISBASE/src/mapdev/digitizers/calcomp/Diagnostics. If none of the programs work, then there is something wrong with either the cabling or the digitizer.
