Config Menu ⇒ Serial I/O

Serial I/O Category

Serial Interface is a style of host com- puter-to-printer I/O communications. It requires certain parameters to be prop- erly set in order for the printer and host computer to communicate. Use the Arrow and Enter keys to select Menu => Config Menu => Serial I/O to get here.

Baud

The Baud parameter allows the user to set up the printer to receive data at different transmission speeds. The baud rate must be the same value at both ends of the communication line. 9600 is the default.

Data Bits

You can choose the number of data bits per byte. 8 bits is the default.

Stop Bits

This parameter sets the number of serial stop bits. 1 is the default.

Parity

Parity is a method the printer uses to verify that each byte of data it receives is exactly what the host computer transmitted. When selected, it keeps track of the number of high bits in each byte (either odd or even). Default is None. The printer must match the parity of the host computer.

8th Bit

If 8 bits per byte is selected under Data Bits above, you use this parameter to determine how the 8th bit is to be used. If this bit is to be ignored, the param- eter should be set to Unused. If the bit is to be used, the parameter should be set to Data. Data is the default, used for 8-bit characters.

Protocol

The printer and host computer must establish common signals, understood by both units, for indicating when to send new data and when to stop sending data. For IPDS, this parameter allows the serial protocol to be set to either Ready/Busy or XON/XOFF. For all other printers, there are six additional block mode protocols. The eight protocols are:

Ready/Busy	(Default selection)
Xon/Xoff
and six Block Mode protocols:
Enq/Ack	(Enquiry/Acknowledge)
Etx/Ack	(End of Text/Acknowledge )
Etx/Ack/Nak	(End of Text/Acknowledge/Neg. Acknowledge )
Ack/Nak	(Acknowledge/Negative Acknowledge )
Xon/off/Etx/Ack	(XON/XOFF/End of Text/Acknowledge )
Xon/off/Enq/Ack	(XON/XOFF/Enquiry/Acknowledge)

The above protocols are explained in detail in the Applications Manual.
