892.0. "LPV16 Installation question" by WINERY::COLLUM () Wed Nov 11 1987 20:01

    I have use of a LPV16 for a few months and I'd like to hook it up
    to the Amiga (using it from Draw Plus).  I have the programming
    manual that comes with it, but no installation manual.  The plotter
    has a little dip switch on the back, and I need to find out what
    the switch settings mean. Does anyone have this info? Has anyone
    tried hooking this beast up to the amiga, and if so, are there any
    gotchas?

    I have an LVP16 with a PRO-380. Never tried with the AMIGA.
    Anyway, I think I can answer your question on the switch settings.
    
    PARITY S1 - PARITY S2
        0          X	    No parity 		x=don't care
        1          0        Even Parity
    	1          1        Odd parity
    
    D/Y Switch - used to establish either programmed "on" or programmed
    "off" operation status. Position D is used when the plotter is directly
    connected to a computer. The plotter will respond to all HP-GL and
    escape sequences. Position Y is used when it's connected between
    a terminal and computer (eavesdrop environment). In this state,
    the plotter will pass information between the terminal and computer,
    but only responds to a plotter "on", "ESC.". It will then respond
    to all HP-GL and escape sequences.
    
    US/MET - Used in combination with the A4/A3 switch to select one
    of four possible default paper sizes.
    
    A4/A3 - Combines with US/MET as follows:
    
    Combination switch setting	Paper Size
    	US/A4			  ANSI A
    	US/A3			  ANSI B
    	MET/A4			  ISO A4
    	MET/A3			  ISO A3
    
    BAUD - select a baud rate.
    BAUD RATE 	One Stop Bit	Two Stop Bits
      		B4 B3 B2 B1	B4 B3 B2 B1
    
    300		0  1  0  1      1  0  1  1
    600		0  1  1  0	1  1  0  0
    1200	0  1  1  1	1  1  0  1
    2400	1  0  0  0	1  1  1  0
    4800	1  0  0  1	1  1  1  1
    9600	1  0  1  0	Not available
    
    If you change any of the switches after power-up, you have to power
    down and up so the logic recognizes the change. Good luck.
    
    I would be very interested in how it works for you, as I might try with
    my AMIGA someday, so please keep in touch.

892.2A couple of tips....OASIS2::BERNARDHave Gun - Will TravelThu Nov 12 1987 21:0859
.1 is correct.  I have mine set up as follows:

                                              Rear SwitchPack
    
                                               B1 = off    |
                                               B2 = on     |   9600 baud
                                               B3 = off    |
                                               B4 = on     |

                                            A3/A4 = A4
                                           US/MET = US
                                              Y/D = D

                                          Parity1 = off
                                          Parity2 = off


This sets the plotter for 9600 baud, direct connect, 1 stop bit, no parity
8 bit word.  I have preferences set for the same parameters using XON/XOFF
handshake.

A gotcha is that the LVP16 powers up in DTS handshake, NOT xon/xoff.  I made a
file with the following control characters:

<ESC>.I81;;17:
<ESC>.N;19:



The first line sets the Xoff threshold to 81 bytes and the Xon trigger 
char to DC1.
The second line establishes the Xoff trigger character to DC3.

Essentially, you are telling the plotter to use XON/XOFF protocol.  Send this
file to the plotter after you initially power it up or at the begining of the
plot stream.

I usually copy it RAW to the plotter by

COPY XON SER:


The printer driver I use seems to trap the XON/XOF control characters.


I have used the plotter to plot out Aegis Draw Plus plot files.  The plotter
type is actually an HP7475A plotter.  It will plot anything in HPGL format.


To connect from the serial port to the printer, all you need to do is use pins
2,3,7,20.



Hope this helps...
