RS-232 Communication Mode Selections

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 4 on page 12 to see how to access the switch.)

Baud Rate Selection

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.

RS-232 Communications Protocol Selection

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.

Use switch 2 on the RS-232 settings switch to select the mode. Switch settings are:

Switch 2 OFF DTR/DSR control

Switch 2 ON XON/XOFF control (must use with a 3-wire interface)

The printer normally ships with switch 2 in the OFF position, which selects

DTR/DSR control.

DTR/DSR Control

DSR Definition: DSR is an output from the printer. It indicates when the printer is ready to receive data.

DTR Definition: DTR is an input to the printer. It indicates to the printer that the system is ready to receive data.

DSR Operation: A DSR signal becomes inactive when the printer is not ready to receive data (for example, at power-on reset or when its buffer is full).
