1.3 INTERFACE SPECIFICATIONS
The Stylus Pro XL is standard-equipped with an 8-bit parallel and serial interface.
1.3.1 Parallel Interface Specifications
Data format: 8-bit parallel
Synchronization: By
STROBE pulse synchronization
Handshaking: By BUSY and
ACKNLG signals
Signal level: TTL compatible level
Adaptable connector: 36-pin 57-30360 (Amphenol) or equivalent
Data transmission timing: See Figure 1-7.
Note:
Transition time (rise time and fall time) of every input signal must be less than 0.2
µ
s.
The Busy signal is active (HIGH) under the following conditions:
❏ During data reception (See Figure 1-7.)
❏ When the input buffer is full
❏ When the
INIT input signal is active
❏ During initialization
❏ When the
ERROR or PE signal is active
❏ During the self-test mode
❏ During the demonstration mode
❏ During the default setting mode
❏ When a fatal error occurs
The
ERROR signal is active (LOW) under the following conditions:
❏ When a paper-out error occurs
❏ When a no ink cartridge error occurs
❏ When a fatal error occurs
The PE signal is active (HIGH) under the following conditions:
❏ When a paper-out error occurs
❏ When a fatal error occurs
