DMP 500  (260-1252)         Dip Switch Settings         Faxback Doc. # 4587

SETTING PRINT FUNCTION SWITCHES

There are 8 switches located at the left rear of the Printer.  These
Switches allow you to customize some of the DMP-500 features for your own
applications.

for instance, by setting the appropriate Switches before turning the
DMP-500's power ON, you can select Word Processing Mode (better print
quality) or Data Processing Mode (higher printing speed).

When you receive the DMP-500, all Switches should be set to OFF (i.e., in
the down position).

REMEMBER!! The Printer power must be OFF before you change any of the 
switches.


If you've been using a Radio Shack Line Printer V (26-1165) and still have
applications programs that are designed to run on the LP V, Switch #1 has
been included for your convenience.

This Switch allows the DMP-500 to treat some codes just like the LP V.

For instance, CHR$(27);CHR$(19) is used to set the LP V into Graphic Mode.
However, the DMP-500 uses a CHR$(18) to go into Graphic Mode.  Therefore,
because Switch #1 has been provided, you won't have to change the program
if it uses a CHR$(27);CHR$(19) to set the Printer into Graphic Mode--just
set Switch #1.

When Switch #1 is in the "up" position (ON), the Line Printer V codes are
used.

When Switch #1 is in the "down" position (OFF), the new DMP-500 codes are
used.

NEW DMP-500 CODES

If switch #1 is set to OFF then the following codes are used:

IF YOU WANT TO:                   USE CHR$( ) CODE:

Start Graphic Mode                18
End Graphic Mode                  30
Start Elongation                  27  14
End Elongation                    27  15
Standard Character                27  19
Condensed Character               27  20
End Bold Character                27  32
Half Reverse Line Feed            27  30

LINE PRINTER V COMMAND CODES

If Switch #1 is set to ON then these codes are used:

IF YOU WANT TO:                   USE CHR$( ) CODE:

Start Elongation                  31
End Elongation                    30
Standard Character                27  15
Condensed Character               27  14
End Bold Character                27  30
Half Reverse Line Feed            27  32

REMEMBER!! Only change DIP Switch settings when the power is OFF.

SETTING THE ROTARY SWITCH

The Rotary Switch is located inside the DMP-500, just behind the Front
Panel.

On power-up, it is used to select the desired character pitch (i.e., number
of characters per inch--CPI). Always set the Switch when the power is OFF.
This is also referred to as character spacing since the DMP-500 adjusts the
space between the font style characters you have selected.  The Switch can
be set by hand, but a small screwdriver makes the job much easier.

When setting the Switch, the vertical groove must be positioned to the
number you want.
