The title of this topic is DXY800 / 880 which are different plotters. The
DXY800 is more like the DXY101 (and the manual says so).

In any case the DIP switches on the DXY800 are for setting the serial
interface - Hopefully you aren't still using that. (Rather than the parallel
interface.)

In any case, for the DXY800 the switches are as follows:

1 300 Baud

2 600 "

3 1200 "

4 2400 "

5 9600 "

7 Parity check ON:Odd OFF:Even

8 Data Bit ON:7bit OFF:8bit

9 Stop Bit ON:1bit OFF:2bit

10 Parity Check ON:Yes OFF:No



Notes:

The dip switch must match the specs of the computer side (parity, top,baud
etc)

For Baud switches be sure only one is on. Also when switching, first turn
all switches OFF then turn the switch for desired baud rate ON.



Another point of interest is, if you press and hold the pen up and home
switches together while powering up it will do a self test of grabbing each
pen and doing a little dance with each pen in the pen up position. If you
press the pen up switch one more time it will do the same with the pens down
(On paper).



There isn't much more of interest in the manual. Just a description of each
command and some example programs to draw something by sending commands
manually.



Someone here also mentioned that the plotters accept HPGL. This is
definitely not true for the 800. This is why I was forced to stop using it
because Windows programs had no drivers for it. The 800 accepts command more
resembling G-code (but not).

BUT I have found out recently that EAGLE PCB supports these old plotters. I
haven't tried it but they're in the output setup choices.

I found cleaning pens and all the problems with them skipping and not making
lines thin enough etc., was more trouble than doing the toner transfer
process.
