SUBJ:   Configuration of DEC LA100 Printers on VAX/VMS Systems

     
     
Due to the very flexible nature of the new LA100 printers (in
terms of their configurability to a variety of different communi-
cation situations, determining an optimum hardware setup of the
printer for our VAX/VMS system was, at first, rather difficult. 
To simplify setting up the next LA100's, I have documented below
a specific configuration that best matches them to our VMS
environment.  (Chapter 3 of the Letterprinter Operator's Guide
contains information regarding selectable features, and gives
further explanation of the options mentioned below.) 

Operator Control Panel

All buttons should normally be in the UP position, unless manual
intervention is desired.  If the paper is sprocket-driven, and
feeds through the bottom of the printer, the PAPER-OUT lever
should be set towards the rear of the printer to enable paper-out
sensing (and so set X-OFF/X-ON as appropriate). The font selector
should be set so that all LED's except one are lit, to enable
computer selection of the fonts.  If any user should alter these
settings, the printer will not operate as desired for other users.

Switch Selectable Features

When setting the following, always use a ball-point pen or
scribe.  Switch A is on left, and Switch B is on right, when
facing printer.  Switch settings are down-active.

<*> Switch A <*>      BAUD RATE   : 2400, NON-SPLIT
                      PARITY      : SPACE
    12345678          DATA BITS   : 7
    RLRLRRRR

<*> Switch B <*>      SPEED/REST  : RESTRAINT
                      MODEM CTRL  : NO MODEM
    12345678          PAPER FAULT : NO ACTION (Uses X-OFF)
    RRRRRLLL
                      CODED DSCNCT: DISABLE
                      X-ON/X-OFF  : ENABLE
                      RCVR ERROR  : PRINT CHARACTER
                      SAVE (STORE): (Move this switch from right
                                    to left to install switch
                                    settings above.)
