Subject: Altek Digitizers
Can someone who is using an AC31 (Altek Datatab) please tell me what
their switch settings are set to inside the box? I'm quite certain that
it's my switches that are giving me such a hard time. Thank you very
much.

Christine,
The settings for an AC30 controller are listed in the grass src directory
in a file called src/mapdev/digitizers/altek/INSTALL.ALTEK but I don't
know if the settings are the same or not. I have been assured by Altek
that the AC31 is functionally the same as the AC30 so I would guess that
the switches might be the same.
Here is the file in case you don't have your src files on line.

Installing an Altek Digitizer.
This file covers how to set up the hardware for an Altek digitizer with an
AC-30 controller. Specifically setting up the AC-30 controller, the cabling
to the digitizer and a help section for problems. At the bottom of this file
there is a description of the AC-40 controller switch setting, but they are
untested.
On our AC-30 controller the switches are inside the controller itself.
Had to remove 4 screws and the cover to get to the switches. There are
two banks of eight switches.
Switch settings:
Left Bank Right Bank
1 --> 1 <--
2 --> 2 <--
3 <-- 3 <--
4 --> 4 <--
5 --> 5 -->
6 --> 6 <--
7 <-- 7 <--
8 <-- 8 <--
ON -->
What these switch settings give us is:
Resolution at .001 inches, format 8 (standard packed binary), 9600 baud,
and point mode.
The cabling between the digitizer and the computer differ for different
computers. Some known cable configurations:
AT&T 3B2: Cable was straight thru (ribbon cable).
SUN 3/110:
Sun Altek
2 ---- 3
3 ---- 2
4 ---- 5
5 ---- 4
7 ---- 7
SUN SPARC Plus
While the above configuration has been known to work for Sparcstations,
it is reported that this below works where the other sometimes
does not:
Sun4 Altek
2 ---- 3
3 ---- 2

MASSCOMP :
Mass Altek
2 ---- 3
3 ---- 2
4 ---- 5

20 _|
Masscomp cable has 2 and 3 switched, 4 and 5 switched, 7 straight thru, and
on the computer side 6, 8, and 20 are looped together.
If the digit program isn't working make sure the tty the digitizer is on
has the getty off, the tty permissions 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 in the altek sub-
directory Diagnostics. Read the README file in the Diagnostics directory for
specific information on the programs. If none of the programs work then there
is something wrong with the cabling or the digitizer.
----------------------------------------------------------------------------
I have two differents sets of digitizers switch setting for the AC-40
controller. If one set doesn't work try the other.
AC-40 Switch Settings:
1 bank of 9 switches
4 banks of 8 switches
----------------------------------------------------------------------------
First set of switch settings to try:
One bank of 9 switches all switches are on.
4 banks of 8 switches:
1st 2nd
--- | ---
8 0 - 9600 | 0 - Mode
7 0 - | | 0 - |
6 1 - | | 0 - Stream
5 1 - | | 0 - |
4 1 - 2 stop | 0 - Strm. Value
3 0 - Dis par | 0 - |
2 1 - Even | 1 - |
1 1 - 8 bits | 0 - |
1 is on, 0 is off
3rd 4th
--- | ---
8 1 - Output | 1 - Binary 2
7 1 - | | 0 - Standard
6 1 - | | 0 - Run Type
5 0 - English | 1 - |
4 0 - No LF | 0 - Serial
3 0 - Dis sign | 0 - DTR1 off
2 1 - X on | 0 - DTR2 off
1 1 - En Host | 1 - Reserved
1 is on, 0 is off
----------------------------------------------------------------------------
If the first set of switch settings fail you may want to try these settings.
One bank of 9 switches all switches are on.
