Cable Wiring

This printer allows two types of serial communication control: DSR-enabled

and DSR-disabled. The type of control required is determined by your

computer requirements. The type of control also affects the way the interface

cable is wired. To determine whether you need DSR-enabled control or DSR-

disabled control, use the printer HARDWRE function (see Chapter 5).

DSR-disabled control offers simpler cabling and communication than does

DSR-enabled control. DSR-disabled control can be used to interface with an

IBM PC and most other personal computers. With DSR-disabled control, the

input control signals DSR, CTS, and CD are always considered high,

regardless of their actual states. Therefore, no wire connection for these pins

is required. The following figure shows the wiring required for connection to

an IBM PC.
