Interfaces
Parallel Interface Configuration
The printer is configured at the factory for the type of interface used, either parallel or serial.
However, certain user selectable configuration options are available. The following configuraĆ
tion parameters can be verified or changed as necessary to meet specific application requireĆ
ments:
n
Input buffer size
n
Sense of Data Line 8
n
Sense of the Paper Instruction line
n
Data Polarity
n
Printer Error Polarity
These parameters are displayed under the Application Compatibility and Interface CompatiĆ
bility menus selectable from the control panel. This data may be latched on either the leading
or the trailing edge of the Data Strobe signal by selecting the appropriate jumper on the Logic
C3 board. Refer to Control Panel Switch Function diagram in the Configuration chapter for
detailed information on selecting the various parameter values.
NOTE: If there are extra or missing characters, try changing the strobe edge select from
leading to trailing.
Centronics Parallel Interface
This interface enables the printer to operate with controllers designed for buffered Centronics
printers. The interface is capable of transferring up to 200,000 characters per second. The
maximum data line cable length from the controller or host computer to the printer is 40 feet.
Centronics Interface Signals
Centronics interface signals between the computer and the printer are defined as follows.
Table 7-2 lists the Centronics interface connector pin assignments.
PE
- A high true level from the printer to indicate the printer is in a check condition.
SLCT
- A high true level from the printer to indicate the printer is ready for data transfer and
the ON LINE switch has been activated.
Busy
- A high true level from the printer to indicate the printer cannot receive data.
ACKNLG
- A low true pulse from the printer indicating the character or function code has
been received and the printer is ready for the next data transfer.
Data Strobe
- A low true, 100 ns minimum pulse from the host to clock data into the printer.
Data Lines
- Eight high true levels from the host that specify a character or function code.
Sensing Data Line 8 is controlled by printer configuration.
+5 Volt Test
- +5 Vdc output for operating a
Printronix
test exerciser drawing up to one amĆ
pere of current.
