RS422 > Centronics Interface, 1+1KByte, Model 62009
The 62009 Interface permits parallel printers or plotters to be
connected to any data source having a serial RS422 port.
Function
When installing, the data format of the Interface must match
the format used by the data source. The RS422 parameters can
be set either by using DIL switches inside the Interface (see
table) or using automatic format detection in „Learn-Mode“.
Learn-Mode
To initialize Learn-Mode you must press the key on the
interface converter as the Interface is being turned on. After
releasing the key the current setting of the Interface is output
on the connected printer. Next a page of any desired text
should be sent to the Interface for purposes of format
detection. The detected RS422 parameters are output on the
printer and automatically stored in a non-volatile EEPROM. The
next the the Interface is turned on (without holding the red key
down), the Interface carries out its normal function using the
newly detected parameters. Learn-Mode can be repeated as
often as desired. In normaly operation pressing the key once
clears the built-in buffer (Clear). Pressing it twice prints out the
buffer contents again (Copy).
Manual setting of the RS422 parameters
In addition to Learn-Mode, the Interface allows you to set the
RS422 parameters manually using DIL switches accessible by
opening the Interface housing.
