Figure 15. SurePOS 500/600 integration
Switch settings described in this section apply only when the printer is connected to
the system with the RS-232 cable. The switch is accessible without removing the
printer covers. (See Figure 5 on page 18 to see how to access the switch.)
SureMark printers support two RS-232 baud rates, 9600 and 19 200. The baud rate
is selected using switch 1 on the RS-232 settings switch. Set the switch as follows:
Switch 1 OFF 9600 baud
Switch 1 ON
19 200 baud
The printer normally ships with switch 1 in the OFF position, which selects the 9600
baud rate.
SureMark printers support RS-232 protocol using either DTR/DSR or XON/XOFF to
control data transmission. XON/XOFF mode uses system and printer software to
control the flow of data. This is called flow control.
