DIP Switch 1:
Meaning of the parallel interface SELECT signal.
Switch on
SELECT represents the COVER SWITCH, i.e.
SELECT = “HIGH”-> cover closed
SELECT = “LOW” -> cover open
Switch off
SELECT indicates whether the parallel or the V.24 interface
is active
SELECT = “HIGH” -> parallel interface is active
SELECT = “LOW” -> serial interface is active
DIP Switch 2 and
These two switches serve to select the compatibility and set the
DIP Switch 3
effects of control commands between the operating modes
ND69 mode
BEETLE/60 mode or
EPSON-TM930 mode
Moreover, the switches are used to execute an AUTOFEED,
i.e. an automatic line feed with the control character CR.
Switch 2 off and
The ND69 is in the ND69 mode and CR is executed without a
Switch 3 off
line feed
Switch 2 on and
The ND69 is in the BEETLE/60 mode and CR is executed
Switch 3 off
without a line feed
Switch 2 off and
The ND69 is in the EPSON-TM930 mode and CR is
Switch 3 on
executed without a line feed
Switch 2 on and
1.
The ND69 is in the EPSON-TM930 mode and the
Switch 3 on
parallel interface is active.
The parallel interface signal AUTOFEED/N
determines whether CR executes an automatic
line feed.
AUTOFEED/N = “HIGH” - CR without line feed
AUTOFEED/N = “LOW” - CR with line feed
2.
The ND69 is in the EPSON-TM930 mode and the V.24
interface is active:
CR is executed with a line feed.
DIP Switch 4:
Selection of DTR/DSR or XON/XOFF control
Switch on
XON/XOFF control is switched on
Switch off
DTR/DSR control is switched on
