1.6 Interface Board
1.6 Interface Board
The interface board can connect to a host system through the following
interfaces.
• Serial RS232C
• DEC423 (Adaptor to the RS232 is required with the DEClaser 1100 and
1150 printers.)
• Parallel 8-bit Centronics
• Video (DEClaser 1100 and 1150 printers only)
• LocalTalk (DEClaser 1152 printer only)
Data passes directly through the interface board. See Section A.3 for pin-out
and connector information.
Note: The interface board affects the printing of the control panel test
patterns. If the interface board is removed, all control panel invoked test
patterns will result in a blank page. The engine test print will print correctly.
1.7 DEClaser 1100 and 1150 Printer Video Control Board
The DEClaser 1100 and 1150 video control board receives commands and
image data from the host system through the interface board. The image data
is compiled into a dot pattern and stored in the page memory to be output to
the laser scanner assembly through the DC control board.
Figure 1–9 shows the major blocks of the video control board.
