ATI Model F12/D Gas Transmitter Part 4 – Operation

O&M Manual (Rev-H)
Data Log Print Menu
The Data Log Print Menu appears by selecting Print from the Data Log Menu (pg 59). The data log
must not be empty, and the communication protocol must be set to ASCII before entry (see 4.11 COM
Menus on pg 66), or an exception message will be displayed. The transmitter’s real time clock should
also be set to the correct date and time.
Figure 81. Data Log Print Menu
To send the report, set the start date (First) and number of days to print (Days), and select Start.
The line will blink Printing until the report is done. The report always begins at 00:00 on the start date,
and continues for the number of days specified. If no data has yet been logged, the report will show four
dashes (----) in place of samples.
Data Log Print Format Menu
The Data Log Print Format Menu appears by selecting Format from the Data Log Print Menu (above)
and is used to control the appearance of the report, and the interaction of the transmitter with the device.

The transmitter adds a CR (ASCII 13) or CR/LF (ASCII 13 and 10) at the end of each line. If the lines of
the report appear to be printing over each other, choose the CR/LF option. If the lines appear to be
double spaced, choose the CR option.
The number of sample data samples (gas readings) appearing across the page is programmable from 1
to 30. This is designed to allow reports to fit on small thermal printers, and on conventional sized printers.
A wider report takes less time to print because the date and time fields are printed less frequently.
A delay of up to 10 seconds can be added after each line is transmitted to help prevent buffer overflows
on printers without XON/XOFF protocol. This is sometimes required to allow slow printers enough time to
perform carriage return. If characters appear to be missing, increase the setting.
Flow Control
The transmitter uses XON/XOFF flow control while sending a report. That is, once the data stream has
begun, it will continue until the XOFF character (19) is received. After sitting idle, the report stream will
begin again upon reception of the XON character (17).
Set the first date to print in the report. Scrolling this date
automatically updates the Days field.
Set the number of days of data to include in the report.
Send the report to the device connected to the transmitter’s
COM port.
Configure the report format for the connected device.
Change the number of data samples (gas readings) printed on
each line.
Toggle the ASCII control code(s) transmitted at the end of each
line from CR to CR/LF (more on this below).
Add up to a 10 second delay at the end of each line.
