Fujitsu DL7400 Manual Do Utilizador

 

 

# indicates an open wire. 

DSR-enabled control enables comm

cation using an RS-232C 

interface.  The CTS and DSR input control signals are enabled; CD is 
ignored.  DSR must be high when the printer receives data.  If the printer 
has data to be transmitted to the computer, the printer transmits the data 
when both DSR and CTS are high. 

When using DSR-enabled control, use a straight-through cable to 
connect to a DCE (data communications equipment) device.  Use a null-
modem cable to connect to a DTE (data terminal equipment) device, as 
shown below. 

 

Wire q is unnecessary for the DTR (or RC) protocol. 
Some computers may not require wire w.
