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.
