B.1.2 PRINT TICKET MODE
The Print Ticket Mode is designed specifically for a serial printer and is selected by setting
A6 to “1”. Figure B-3 shows the fixed format of the print ticket.
For printers with limited buffers, this mode supports DTR pin handshaking. The DTR pin
from the serial printer is wired to the indicator’s RXD pin which then functions as a CTS pin.
Figure B-4 shows a suggested cable diagram for interfacing to a serial printer. Refer to the
printer’s user manual to confirm which pin is the DTR pin.
