Communication Interfaces 10-8 Data Signals Character transfers from the host to the receiver consist of 8-bit data bytes (DA T Al through DA T A8) traveling in parallel over the eight data lines. DA T Al is the least significant bit and DA T A8 is the most significant bit. If a 7-bit character set has been selected, the DA T A8 line remains low for[...]

Communication Interfaces 10-9 Busy Signal This active-high signal from the printer indicates that the printer is busy and cannot accept additional data. During data-transfer operations, the leading edge of the host-generated strobe signal activates BUSY for each character-transfer cycle. The printer sends an acknowledge pulse and deactivates BUSY a[...]

Communication Interfaces 10-10 Paper-Empty Signal The paper-empty (PE) signal from the printer indicates that the paper supply is empty . The printer activates this signal in combination with the fault signal to indicate the paper-empty condition to the host. Select Signal The select (SLCT) signal from the printer indicates to the host that the pri[...]

Communication Interfaces 10-1 1 The following figure shows the timing sequence for host-to-printer character-transfer operations. The table on the following page lists the timing requirements for the operation. The reference points, a through h in the preceding figure, are keyed to the table on the following page and to the following character-tran[...]

Communication Interfaces 10-12 3. The printer activates ACK- ( e ) to signal the host that the receive buffer has received the character . 4. If the character does not fill the receive buffer , the printer deactivates BUSY and ACK- ( f ) to notify the host that the transfer operation is complete. The host can then initiate another data-transfer cyc[...]

For normal write cycles (receive buffer not full), this occurs at 10 µ s min., 500 µ s nom., and 1000 µ s max. after the leading ed[...]

Communication Interfaces 10-14 Error Conditions F AUL T- and PE are printer status lines. The printer activates F AUL T- to indicate a mechanism failure, such as a paper jam, and deactivates it when the error is corrected. After the paper supply is depleted, the printer activates both PE (paper empty) and F AUL T- to indicate the paper-empty condit[...]

Serial Interface Connector The serial communication interface transfers either 7-bit or 8-bit character information in an asynchronous, bit-serial format. This format is useful for transferring data over long distance lines via data communication devices such as modems, but it can also be used to transfer data directly between the host and the prin[...]

Communication Interfaces 10-16 Interface Signal Descriptions The following paragraphs describe the serial interface signals. Protective Ground The protective ground (PG) line is connected directly to the power cord ground to provide protection for the equipment and personnel. Signal Ground The signal ground (SG) line is connected to the printer pow[...]

Communication Interfaces 10-17 Clear to Send Signal The host computer generates the clear to send (CTS) signal to indicate that it can receive data from the printer . In the DIRECT CONNECT mode, the printer ignores this signal. In the MODEM CONNECT mode, CTS must be on for the printer to send data. If the interface cable does not provide a connecti[...]

Communication Interfaces 10-18 Interface Data T ransmission Rate Because data-transfer operations on the serial interface occur in a bit-serial fashion, the data transmission rate is measured in bits per second, commonly called the baud rate. T o provide compatibility with a variety of systems, your printer offers the following range of baud rates.[...]

Communication Interfaces 10-19 In addition to the data bits, each character contains the following bits. q Start bit — A bit immediately preceding the character bits that signals the start of the asynchronous data transmission. q Parity bit — A bit immediately following the character bits that allows the printer to check the integrity of the re[...]
