18.020 How can I connect my Imagewriter II to a PC?

       You can do Text printouts from your PC to IW-II by selecting the C-Itoh 8510
as your printer in Windows 3.1 up through at least ME. (Just go to settings:
printers: new and select the c-itoh 8510.) The connection from the IW-II must
go to a serial port-- e.g. COM-1 or COM-2.

   The cabling information shown below is from the the Imagewriter II manual.
It's the connection to an RS-232C port. Including pin 5 in the jumpered pins on
the 25-pin side is an addition. I'm not sure how important it may be. Perhaps
it is added to allow diagnostic testing.)

   If you make your own, you need an 8 pin mini-DIN circular male connector, a
DB25 female connector, and 5-conductor shielded cable. Up to 20 meters should
be OK.

   Cable details as follows...

   8 pin               25 pin
 
   DTR 1 ---------   *- 5 CTS * 5,6,8 are jumpered
                     *- 6 DSR   together at db25 end.
                     - 8 DCD
 
   DSR 2 ---------     20 DTR
 
   TD- 3 ---------      3 RD
 
   SG  4 *-------      7 SG
   RD+ 8 **
   ** 4 and 8 are
      jumpered
      together
      at 8-pin end.
 
   RD- 5 ---------      2 TD
Connector SHIELD or pin 1 (PG) connected to cable shield on DB25 end. (Only one end of the cable shield needs to be connected to the connector shield.) One alternative is to use a IIe (SSC) to IW-II cable (part #590-0335) plus a standard NULL modem cable plus any gender changer connector (or 25 to 9 changer) necessary to connect to the PC COM port you want. The standard basic NULL modem 'cable' (or 'adapter') is two Dsub 25-pin female sockets, call them "A" and "B", wired back-to-back as follows (arrows indicate signal direction):
      Socket-A            Socket-B
 
       TXD   2    ->      3  RXD
       RXD   3    <-      2  TXD
       RTS   4    ->      5  CTS
       CTS   5    <-      4  RTS
 DSR & DCD  6&8   <-     20  DTR
       GND   7    --      7  GND
       DTR  20    ->     6&8 DSR & DCD
The two cables (plus gender/9-pin adaptors as needed) give you the connection described in the IW-II manual. A CrossWorks cable (plus adaptors as needed) is supposed to work, too. Either the homebrew cable or one of the combinations of existing cables mentioned should allow a hardware handshaking connection at 9600 baud. For the C-Itoh 8510 printer, go to "Properties" (in the Files menu). For Port settings, select the correct COM port. Data bits, parity, stop bits should be the usual 8-N-1. Speed or baud rate should be 9600. Flow control should be Hardware. On your IW-II, DIP switch 2-3 should be Up (open). Yet another alternative is to use a IIgs or Mac high-speed modem cable (e.g. part 950-0109) connected to a NULL modem plus adaptors as needed. This works fine; but, you will lose the hardware control lines and need to switch to Xon/Xoff handshaking. In "Properties", Flow control should be Xon/Xoff. On your IW-II, DIP switch 2-3 should be Down (closed).
