Interface Data Transmission Rate | Epson 8900 Series guide

Interface Data Transmission 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. To provide compatibility with a variety of systems, your printer offers the following range of baud rates.

q300 bits per second

q600 bits per second

q1200 bits per second

q2400 bits per second

q4800 bits per second (the default value)

q9600 bits per second

q19,200 bits per second

The control panel setup menu (described in Chapter 2) allows you to select the appropriate baud rate for your system.

Serial Data Format

The following figure shows the data format for 7-bit and 8-bit characters. The serial interface can transfer (and the printer can accept) either 7-bit characters or 8-bit characters, depending on which character set is in use. In either case, data bit 1 is the least significant bit (lsb) and the last bit is the most significant bit (msb).
