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.
