How to communicate with a Macintosh:

Model:  53336/53436 (DM-600/800 series)

A.   HOW DO YOU CONNECT THE PLOTTER TO A MACINTOSH:

     Please Note: This plotter series supports CalComp 907/PCI vector
     format, the CalComp Raster Format (CCRF), HPGL, and HP/GL2 (HP 7600
     emulation). HP/RTL is not supported.

     The DM-600/800 also supports TIFF and CALSG4. For detailed
     information print TIFF and CALSG4 files, refer to the Plotter
     Reference Manual (P/N M0016-440). The DM-600/800 User's Guide P/N
     is M0016-420.

     Neither PostScript nor the AppleTalk interface are supported. (The
     Print Bridge, model 86625, may used as an external interface for
     PostScript Level 1 support.)

     1.   CONNECT ONE OF THE PLOTTER'S SERIAL PORTS TO THE MAC'S MODEM
          PORT:

          The port marked COM_2  is configured at the factory as a
          serial plot data port. COM_1 is configured the OPCOM port,
          designated for terminal operations. (For detailed information
          on OPCOM, please refer to chapter 1 of the Plotter Reference
          Manual.

          a.   On the back of the plotter are 3 ports, the one marked
               COM_1/OPCOM is an  RS-232 25-pin serial port (female,
               DB25). This port is configured by the factory  for
               OPCOM. It cannot be used for plot data unless the OPCOM
               link is switched off. You can switch COM_1 from OPCOM to
               a plot data port at the Control Panel (see the chapter 4
               of the User's Guide, pages 4-43 through 4-47).

          b.   To make a serial connection you need CalComp's Mac cable
               P/N 16623-0029 (12' cable) or 16623-0011 (6' cable) AND
               the CalComp Null Modem Adapter P/N 21617-0019. This
               adapter is usually included as a standard item when the
               plotter is purchased.  The CalComp cable connects
               directly to the Mac's MODEM port and the adapter end
               connects to the DM-600/800's COM_2 port. If you wish to
               extend the lengthen this cable (up to 50'), add a
               straight-through extension cable (CalComp P/N 11772-020
               is a 25' heavy duty extension cable).

          c.   Another way to make a serial connection with the Mac is
               to use an ImageWriter One (Mini DIN-8) serial cable
               (connected directly to the Mac) with a different CalComp
               adapter (then the one mentioned above) attached (CalComp
               P/N 21616-0010). The ImageWriter One cable connects
               directly to the Mac's MODEM port and the adapter end
               connects to the DM-600/800's COM_2 port. If you wish to
               extend the lengthen this cable (up to 50'), add a
               straight-through extension cable (CalComp P/N 11772-020
               is a 25' heavy duty extension cable).

     2.   CONFIGURE THE PLOTTER'S SERIAL PORT FOR THE PLOTTER DRIVER:

          a.   For most CAD applications (the one exception being
               AutoCAD), CalComp recommends MacPlot Professional.
               MacPlot Professional is a Chooser level driver supplied
               by Microspot (408-257-4000). MacPlot Professional fully
               supports the CalComp 907/PCI standard. For more details,
               please see the problem summary note; WHAT DRIVER SHOULD
               BE USED WITH A MACINTOSH.


               The DM-600/800 automatically configures itself for
               CalComp 907/PCI, CalComp CCRF,  HPGL, and HP/GL2
               (emulating an HP 7600 only). This means that only the
               following  serial port parameters must be configured:

                         PORT
                      PARAMETER
                       REQUIRED                       EXAMPLE
                   =============================================
                     Baud Rate  -----------------------  9600
                     Character Framing  ---------------  7,E,1
                     Plot Data Protocol  --------------  CTS
                     Stepsize  ------------------------  400

               The computer and plotter must match in baud rate, data
               bits, stop bit, & parity (data bits, stop bit, and
               parity are known together as the character or data
               framing), and handshake. The handshake is called Plot
               Data Protocol (on the plotter s serial port
               configuration list) and is either CTS (which means Clear
               To Send and stands for hardware handshaking. Hardware
               handshaking is also known as Direct Control), Xon/Xoff,
               or Ack/Nak.

               The above parameters must match what is setup on your
               Mac system. First, configure the Mac, then go to the
               plotter's Control Panel and setup the plotter to match.
               This is accomplished under the Control Panel menu option
               called PORT SETUP (detailed information on PORT SETUP is
               found in the User's Guide, starting on page 4-43).

               The default serial configuration for the Mac is:  9600,
               7, 1, E, and CTS handshake

          b.   BE SURE TO MATCH THE STEPSIZE:

               CalComp 907/PCI plot files include a Stepsize (steps-
               per-inch) upon which vectors are precisely calculated.
               The Stepsize is NOT Autosensed by the plotter. The
               Stepsize must be configured in the Control Panel, under
               PORT SETUP.

               The Stepsize on the plotter must match what the CAD
               application software's plotter driver is configured for.
               The factory default Stepsize settings are; 300 dpi for
               the 53336 and 400 dpi for the 53436. Both plotters may
               be set for the most commonly used Stepsize settings of
               300, 400, 1016, and 2032. The Stepsize DOES NOT impact
               the resolution quality of the plot file - only the
               internal vector calculations..

               When there is a Stepsize mismatch, the plot will come
               out either much too small or much too large.

     3.   VERIFY PLOTTER OPERATION BY RUNNING THE DEMO PLOT:

          Run the plotter's Demonstration Plot (DEMO PLOT 1). Please see
          the User's Guide, page 5-2. If the demo plot runs, it means
          the plotter's basic operation is sound.


B.   HOW TO MAKE A CENTRONICS PARALLEL CONNECTION:
     The Mac is not manufactured to support a centronics parallel
     interface. They do, depending on the model type, provide a certain
     number of open slots so that an interface card could be added. This
     note refers only to the MacPlot raster mode driver, which require a
     parallel interface.

     1.   The plotter's parallel port can be used with a Mac if the
          customer purchases MacPlot Electrostatic DMA  (NOTE: The MONO
          version of  MacPlot Raster designed for CalComp's mono inkjets
          may also support the DM-600/800 plotters - please contact
          Microspot at 408-257-4000 for the latest driver update info).
          This package comes with a CCRF raster driver and a parallel
          card for the Mac. It works ONLY on the plotter's parallel
          port. This driver will allow customers to plot anything from
          the Mac, including photos and gradient fills, etc., however,
          it is not the best choice when the you want to run strictly
          CAD applications. This is because it is vector mode driver is
          optimized for CAD and can plot CAD entities much faster than a
          raster mode driver.


C.   THE PLOTTER IS NOT RESPONDING ALTHOUGH THE DRIVER AND CABLE 
       ARE CORRECT:

     1.   VERIFY PLOTTER OPERATION BY RUNNING THE DEMO PLOT:

          Run the plotter's Demonstration Plot (DEMO PLOT 1). Please see
          the User's Guide, page 5-2. If the demo plot runs, it means
          the plotter's operation is sound.

     2.   CONFIRM YOUR CABLE CONNECTION: Double check that your cable is
          connected to the plotter COM port configured to work with your
          Mac software plotter driver. Be sure there is good, solid
          connection. Be sure that it IS the correct type of cable
          specified by CalComp's documentation.

     3.   Be sure the plotter and the Mac EXACTLY match in baud rate,
          character framing, and handshake (known on the plotter as Plot
          Data Protocol). All of these parameters are very easy to setup
          on the plotter's Control Panel, under the PORT SETUP menu
          option (User's Guide, starting on page 4-42).

          If you are not sure how the Mac is configured, please refer to
          your Mac user's guides or the application software's help
          references. CalComp does not provide in-depth assistance on
          any product other than the ones we manufacture.

     5.   IF A SWITCH BOX IS BEING USED:  (A/B manual or electronic)
          Switch boxes often create connectivity problems which can only
          be isolated and confirmed by removing the switch box and
          running a test. Remove the switch box and try to run another
          plot from your application. If the plotter now works correctly
          then you may be sure that there is good basic connectivity
          with your Mac computer and the CalComp plotter.

          CalComp provides assistance only on equipment which we
          manufacture. If  problems appear to occur only while a switch
          box is connected, please contact the switch box manufacturer's
          help line or consult their support documentation.

     6.   OTHER POSSIBLE CAUSES:

          a.   Defective cable
          b.   Defective Mac MODEM port
          c.   Defective Mac parallel port (if MacPlot DMA or
               equivalent is being used)
          d.   Defective CalComp plotter COM port (or parallel port -
               if MacPlot DMA or equivalent is being used)

     7.   TROUBLESHOOTING GUIDELINES:

          This step (a) presumes that the port configuration on the
          plotter matches EXACTLY what is setup on the Mac, and the
          plotter is able to run its Demonstration Plot.

          a.   SERIAL CABLE TEST: Test the serial cable for correct
               *pin assignments, electrical continuity, and possible
               shorts (A short occurs when cable wires which should be
               isolated are connected to one another. For example;
               pin's 1 on both ends of the cable are supposed to be
               connected and test OK, however, pin 1 and pin 3 also
               test as being connected - this is a short).

               Another way to test is to try a second serial cable that
               is currently working with  another printer or plotter.
               Be sure the second serial cable meets the CalComp
               plotter requirements. If your tests prove that you have
               a good serial cable but the plotter still does not work
               Call CalComp for assistance 1-800-CALCOMP (800-225-2667).

               i.   CABLE ADAPTER TEST: Check out the adapter using the
                    above method. A wiring diagram for CalComp's
                    ImageWriter cable adapter is given on page 2-7 of
                    the User's Guide.

          b.   PARALLEL CABLE:  One way to test a centronics parallel
               cable is to connect it to any other device which
               supports parallel (MOST printers have a centronics
               parallel port) and is currently in use as a parallel
               device. If the cable being tested does not work, it is
               probably defective. If it does work, either the plotter
               port setup is wrong, the plotter port is defective or
               the computer port is defective.

               Another way to test is to try a second parallel cable
               that is currently working with another printer or
               plotter.

          c.   THE COMPUTER OR PLOTTER  MAY HAVE A DEFECTIVE INTERFACE:

               This step presumes you have a good cable, the port
               configuration on the plotter matches EXACTLY what is
               setup on the Mac, and the plotter is able to run it's
               Embedded Controller test.

                i.  SERIAL INTERFACE:  The Mac may give a
                    communications error if it has an internal hardware
                    problem (refer to your Mac helpline or
                    documentation for further information on error
                    messages which are displayed). Whether or not Mac
                    system errors have been displayed, perform the
                    following test:

                    ia.  Reboot the Mac while holding the SHIFT key
                         (this allows the Mac system to come WITHOUT
                         loading any INIT programs).

                    ib.  Try to plot again. If  the plotter works
                         there is apparently a system conflict on your
                         Mac involving one or more of the INIT
                         programs. CalComp does provide assistance in
                         isolating and resolving system conflicts.

                    ic.  If there were NO error messages and the
                         plotter still doesn't work, try a different
                         computer. ANY computer (IBM or Mac) can be
                         used to test the plotter further. If another
                         computer setup with all of the correct
                         configuration parameters and cable is used
                         and the plotter does not work, call CalComp
                         for assistance 1-800-CALCOMP (800-225-2667).

               ii.  PARALLEL INTERFACE:   The Mac may give a
                    communications error if there it has an internal
                    hardware problem (refer to your Mac helpline or
                    documentation for further information on error
                    messages which are displayed). Whether or not Mac
                    system errors have been displayed, perform the
                    following test:

                    iia. Reboot the Mac while holding the SHIFT key
                         (this allows the Mac system to come WITHOUT
                         loading any INIT programs).

                    iib. Try to plot again. If  the plotter works
                         there is apparently a system conflict on your
                         Mac involving one or more of the INIT
                         programs. CalComp does provide assistance in
                         isolating and resolving system conflicts.

                    iic. If there were NO error messages and the
                         plotter still doesn't work, try a different
                         computer. ANY computer (IBM or Mac) can be
                         used to test the plotter further. If another
                         computer setup with all of the correct
                         configuration parameters and cable is used
                         and the plotter does not work, call CalComp
                         for assistance 1-800-CALCOMP (800-225-2667).
