Serial Port Features

The serial port features are as follows:

Baud rates 300, 600, 1200, 2400, 4800, 9600, 19.2K

Bit patterns 8-bit, no parity; 8-bit odd; 8-bit even; 7-bit no parity; 7-bit odd; 7-bit even

Flow control DTR and XON/XOFF

Table 14 Serial bit rates

It should be noted that the 7-bit, no parity is in fact an 8-bit format. The implementation of the

hardware UART in the Intel 8051 family will not allow a true 7-bit, no parity format. If the host

provides a true 7-bit, no parity format, it must be configured with two stop bits.

The Series 150 Printer has a 64-character high-speed buffer before the main system buffer. This

high-speed buffer allows the printer to operate at high serial data rates while printing. Because

no data is evaluated in this buffer, the printer will have a delayed response to inquire requests

and [CR]’s in one-line operation. This has a significant effect on one-line mode operation.

Table 15 Serial port pin-outs

Because both the host and the printer are DTE's (Data Terminal Equipment), they use the same

serial port pin-outs. If the cable that is used to connect the host to the printer is a pin-to-pin

interconnect, it will not work. For this reason, a null modem or turn-around cable must be used to

interconnect the host and the printer.

Signal levels

The serial interface meets EIA RS-232 requirements.

Logic 1 -15 V to -3 V: mark = off

Logic 0 +3 V to +15 V: space = on
