Modem cables

Connecting Screenblock to a computer
Screenblock has a 9 way RS232 port at the back.  Your computer will have a 9 way RS232 port at the back.  The 9 way to 9 way RS232 modem cable that will connect the two, can be purchased from us or any computer shop.  If you'd like to check the cable, here is the wiring diagram.

If your computer is more than 4 years old, you may find that it has a 25 way RS232 port instead of the more modern 9 way RS232 port.  In this case you will need to buy a 25 to 9 way adaptor from any computer shop.
