8 Printer Output
8.1 General Information
All Anatel A643a Analyzers are equipped with an output port for a local printer, although the
643a–P is already equipped with an integral printer. Automatic hardcopy reports are generated
periodically, although printouts detailing individual Analyzer and global Network information
can be produced on demand through the Print Key. This function also furnishes access to the
Analyzer’s data log permitting the contents to be printed or its memory erased.
8.2 Hardware Setup
Printer connections are made to the PRINTER Port on the Analyzer’s Connector Block. This
RS-232C interface communicates at 1200 baud, 8 data bits, 1 stop bit and no parity. Three- or
five-conductor cable is adequate for most serial interfaces (AWG 24 is recommended),
depending on the particular printer.
Always disconnect the instrument from its power source before attempting to access internal
components.
When supplied by Hach Ultra, the local printer’s interface cable is provided.
Printer output connections are made on the Analyzer’s I/O Connector Block as follows:
1) Turn the instrument OFF and disconnect the power cord from its source.
2) Remove the I/O Connector Block from the bottom of the Analyzer by loosening its four
screws.
3) Loosen and remove the two screws that secure the metal strain relief plate.
4) Feed the interface wiring through one of the five holes at the end of the Connector
Block cover and along the corresponding slot in the foam padding.
