9. RS-232 Serial Port
9.1 RS-232 Port Description:
The ST1LE has a general purpose RS-232 Port which may be used for any one of the following purposes:
Transaction Printing
Data Logging
Remote Metering by Modem (optional)
Computer Communication Link
Configuration by Computer
Print System Setup
Print Calibration/Malfunction History
9.2 Instrument Setup by PC’s over Serial Port
A Diskette program is provided with the ST1LE that enables the user to rapidly configure the ST1LE using a Personal
Computer. Included on the diskette are common instrument applications which may be used as a starting point for your
application. This permits the user to have an excellent starting point and helps speed the user through the instrument
setup.
9.3 Operation of Serial Communication Port with Printers
ST1LE’s RS-232 channel supports a number of operating modes. One of these modes is intended to support operation
with a printer in metering applications requiring transaction printing, data logging and/or printing of calibration and
maintenance reports.
For transaction printing, the user defines the items to be included in the printed document. The user can also select what
initiates the transaction print generated as part of the setup of the instrument. The transaction document may be initiated
via a front panel key depression, a remote contact closure, or upon completion of a batch.
In data logging, the user defines the items to be included in each data log as a print list. The user can also select when
or how often he wishes a data log to be made. This is done during the setup of the instrument as either a time of day or
as a time interval between logging.
The system setup and maintenance report list all the instrument setup parameters and usage for the current instrument
configuration. In addition, the Audit trail information is presented as well as a status report listing any observed
malfunctions which have not been corrected.
The user initiates the printing of this report at a designated point in the menu by pressing the print key on the front
panel.
