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:

Cabling
-------
The cabling between the digitizer and the computer differ for different computers. Some known cable configurations for port A/C:
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).
2 ---- 2
3 ---- 3
7 ---- 7
-------------------------------------------------------
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.
