Null Modem & Printer Cables

Null Modem Cables & Adapters

These cables and adapters are configured such that a computer can communicate to another computer without a modem (thus “null” modem) or a computer can communicate with a printer. Essentially, a null modem cable or adapter reverses pins 2 and 3 (transmit or receive). To complete the communication of a DB25 to DB25 cable or adapter the configuration is as follows: 1-1, 7-7, 2-3, 3-2, 4 & 5-8, 8-4 & 4, 6-20 and 20-6.
