     No. Pins 1 & 2, 3 & 5, and 6 & 8 are swapped from one end of the cable to 
the other.

     Yes; while a number of settings are the same; there are some differences 
between IW-II and IW-II LQ in DIP switch settings as well as which DIP switches 
are present.


DIP Switch Settings

     In Imagewriter manuals, "SW-1" refers to DIP switch module 1. Each such 
module has several individually numbered switches. For example SW-1 #5 refers 
to switch #5 on the SW-1 module. When a switch is UP it is open. When a switch 
is Down it is closed.

     
     The settings for SW-1 #1-#8 have to do with printout format. On SW-1 all 
of the switches are normally open (UP) except #6 which is closed (DOWN). These 
settings work for printouts under Appleworks and several other programs which 
take care of page breaks. For tasks like listing a program, doing a hex dump in 
the monitor, etc. you may want SW-1 #5 to be DOWN. (This enables automatic 
skipping over perforations between pages).


Character Set
SW-1        #1  #2  #3

American     U   U   U  default
Italian      D   U   U
Danish       U   D   U
British      D   D   U
German       U   U   D
Swedish      D   U   D

Form Length

12 inches  D


Auto Perforation Skip
SW-1      #5

No         U  default
Yes        D


Character Pitch
SW-1      #6  #7

10 cpi     U   U
12 cpi     D   U  default
17 cpi     U   D
160 dpi    D   D (proportional)


Line Feed with Carriage Return
SW-1      #8

No         U  CR only
Yes        D  CR plus LF

   
     The settings for SW-2 #1-#6 are concerned with hardware interfacing. #1
and #2 set the baud rate the printer will expect:

#1        #2
UP        UP-    300 (on IW-II)      19200 (on IW-II LQ) 'LQ default
DOWN      UP-   1200
UP        DOWN- 2400
DOWN      DOWN- 9600  IW-II default
 
You should set the switches to match the speed of your printer interface.


SW-2 #3 is usually set UP to enable DTR hardware handshaking. If your
interface wants to use XON/XOFF handshaking, set #3 DOWN.

If you have the 32K Memory Option, LocalTalk card, etc. installed, SW-2 #4
should be set DOWN. Otherwise, it should be set UP (the usual setting).

IW-II: SW-2 #5-#6 on the IW-II are factory-set to optimize hammer firing and 
should be left alone by the use (On my IW-II #5 is DOWN and #6 is UP.)

'LQ: SW-2 #5-#7 on the IW-II LQ are used to set the number of cut sheet feeder
bins attached to the printer. (The standard default setting for SW-2 #5-#7
is UP  UP  UP.)


'LQ: SW-3 #1-#5 (only on the 'LQ)  are factory-set to optimize printer 
operation and should be left alone by the user.

'LQ: SW-3 #6-#8 (only on the 'LQ)  control vertical allignment of dots in
bidirectional printing mode.


The 'LQ Allignment Test

     With printer OFF, press Select, Line Feed, Form Feed.  Hold them pressed, 
turn ON printer, and release buttons after printer head starts to move.

     The printout shows four possible switch settings with six lines of 
vertical bar printouts for each setting.

     Settings are indicated like this:  1  0  0  (which means  DOWN  UP  UP). 
An asterisk by a setting means it is the current setting.

     Set the switches to the setting which best lines up the vertical bars in 
the printout.
