This appendix provides technical information for the parallel and serial interfaces
11.. TThhee PPaarraalllleell IInntteerrffaacce
The parallel interface of this printer fully supports the Centronics protocol plus the specific features
requested by the EPSON and IBM printer connection in monodirectional mode and the Compatibility
and Nibbles modes in bidirectional mode, plus the negotiation phases and the device identifier (as IEEE
P1284).
The parallel interface is available on a specific 36 contact connector type AMPHENOL
57-40360-12-D56 or equivalent connector for 1284 Type B.
• Drive Capability
Up to 15 feet (5 m) on AWG26 min. wire size of twisted conductors on TTL receiver. The max.
reachable distance is conditioned by the host drive capability and by the noise level along the
interface cable path.
• Printer Connector Type
36 pins, 1284 Type B
• Cable Connector
25 pin, 1284 A Type
e
SSiiggnnaallss DDeessccrriippttiioonn
According to the IEEE - P1284 Standard, the pins assume different meanings and are identified by
different names depending on the actual handshaking mode as follows:
• Compatibility mode (Centronics)
This is the lower level mode provides an asynchronous, byte-wide forward (host-to-peripheral)
channel with data and status lines used according to their original definitions. The interfaces power
up in the compatibility Mode Idle phase.
• Nibble Mode
This mode provides an asynchronous, reverse (peripheral-to-host) channel, under control of the
host. In this mode, peripheral device to host data bytes are sent as two sequential, four-bit nibbles
using the four peripheral-to-host status lines. These two modes cannot be active simultaneously.
• Byte Mode
This mode provides an asynchronous, byte-wide reverse (peripheral-to host) channel based on
eight data lines of the interface for data and the control/status lines for handshaking. Byte mode is
under host control and it cannot be simultaneously active with compatibility mode.
OOppeerraattiinngg PPhhaassees
s
The link protocol is mainly based on the following three phases:
• Negotiation Phase
This phase is activated always by the host, only when in compatibility mode, and defines:
- whether a bidirectional link protocol can be established.
- the handshaking mode as well as the communications mode to be used.
- the device identification, if supported.
• Communication Phase
This phase is based on well defined handshaking rules which depend upon the selected link mode.
• Termination Phase
This phase is initiated by the host and returns the interface to the compatibility mode.

initialization time. The BUSY line is always active.

full, and when a paper jam, paper end or paper size error occurs, in
case of a power-on reset, the reception of a STROBE signal, while
the register was not yet read, or when the INIT line is still active.

Timing and Handshaking depend upon the connection mode.
Mode Centronics:
Our Centronics mode supports the BUSY-WHILE-STROBE busy signal timing and
ACK-WHILE-BUSY as BUSY-ACK relationship.

This printer provides the RS-232/C serial interfaces. The interface mode is selected via EDS menu.
• Transmission Type
Data is sent and received in start/stop (asynchronous) transmission.
• Character Format
Each character is transmitted in the following format:
1 START BIT + 8 DATA BITS + 1 PARITY BIT + 1 STOP BIT
The least significant bit of the data bits is sent first after the start bit. The number of data bits is
selected via menu. The parity bit, when present, follows the data bits. The start bit is a logical "0"
and the stop bit is a logical "1". The start and stop bits are used as character framing bits.
• Printer Connector
Male DB9 .
• Drive Capability
Max. 50 feet (15 m) for all supported data rates.
