Plotter displays: HOST DATA PARITY ERROR or DATA FRAMING ERROR message.

A.    Host Data Parity/Host Data Framing error causes:
      
      1.    The computer and plotter require matching setup values for baud
            rate, data bits, parity, stop bits, and handshake. If there is a
            mismatch between the two, then an error will occur.
            
            a.    Data bits can be set for a value of 7 or 8.
            
            b.    Stop bits can be set for a value of 1 or 2.
            
            c.    Parity can be set for a value of odd, even, or none.

B.    Obtain/modify configuration settings in the software application.
      
      1.    If sending files to the plotter from a network,  the network is
            in control of these values.
      
      2.    If using true Windows-based application programs,  the Windows
            driver set-up (in Control Panel Printers) is in control of these
            values.
            
            a.    AutoCAD 12/13 for Windows have their own drivers and bypass
                  the Windows Control Panel Printers configuration.
                  Consequently, the configuration settings are in AutoCAD
                  12/13 for Windows and may be accessed via the AutoCAD
                  command: CONFIG.
      
      3.    If a background spooler is being used to send the plots, then the
            spooler is in control of these values.
      
      4.    If a DOS based software program is being used without networks or
            a spooler, then the software program is in control of these
            values.

C.    Once the configuration setting are known, configure the plotter to
      match what the software is using.  Perform the following:
      
      1.    Turn the plotter power on.
      
      2.    Load and size the media.
      
      3.    Press the EXIT key on the plotter's keypad.
      
      4.    Press the NEXT key twice.
      
      5.    Select SETUP by pressing the softkey above setup (the soft keys
            are the four light colored keys that surround the plotter
            display(window).
      
      6.    Select HOST by pressing the softkey under HOST.
      
      7.    Select BAUD RATE and set it to value that software is using. If a
            selection choice is available, the recommended value is 9600.
            Note: The plotter will not plot any faster with baud rates above
            4800.  Press EXIT once.
      
      8.    Select DATA by pressing the softkey under DATA. Set the value to
            the value used by the software application.
            
            a.    If the software application is using:   8 data bits, 1 stop
                  bit, no parity, and hardware (direct control) handshake;
                  set the DATA menu as follows:
                  
                  i.    Press the top left softkey to change to 8 BIT.
                  
                  ii.   Press the top right softkey to change to 1 STOP.
                  
                  iii.  Press either of the lower softkeys to select NONE.
                  
                  iv.   Press the EXIT key once.
                  
                  v.    Press the HANDSHAKE softkey. Change to DIRECT
                        CONTROL.
                  
                  vi.   Press the EXIT key three times and save as USER #(1
                        through 4) and press the YES button.
                  
                  vii.  Press the EXIT key and then press ONLINE. The plotter
                        should display: HOST PLOT TIME 00:00:00.

D.    If still having problems, note the following:
      
      1.    If the plotter is connected to a switch box, a network, or buffer
            box, then for testing purposes, remove them and directly connect
            the plotter to the computer and then try plotting again with a
            new media sheet loaded in the plotter.
      
      2.    This plotter uses a straight-through 25-pin to 25-pin serial
            cable (CalComp part #11772-0102, 10 ft. serial cable, or part
            #11772-0250, 25 ft. serial cable).
            
            a.    The serial port on a PC is either a 9-pin or 25-pin male
                  port (pins sticking out). Connecting a 9-to-25-pin adapter
                  (available at a local computer supply store) is acceptable,
                  either at the computer-end or at the plotter-end.
            
            b.    The serial cable must be no longer than 50 feet.
      
      3.    If the application allows a choice for handshake, select Hardware
            handshake (sometimes called CTS, hardwire, direct control, or
            DTR/RTS). Match the value on the plotter which is listed as
            DIRECT CONTROL, as described in the above example.
      
      4.    Try a slower baud rate. Again, sending data above 4800 baud will
            not produce plots any faster.
      
      5.    It is possible that the port on their computer is not working.
            Additionally,  a PC with an internal fax/modem installed might be
            sending/receiving data concurrently via a TSR program.
            
            a.    Try connecting to a different port.
            
            b.    Try connecting to a different computer.
            
            c.    Try using a different serial cable.
