Display Pointers
This file is a display of the current status of the data storage memory. The current pointer position and number of full
memory locations is shown. Rarely used.

Printer Output Port
The Printer port on the back of the APDA-371 is an output-only RS-232 serial interface which may be used with a serial
printer or as a diagnostic output to a computer. The printer port output can be configured by using the “a” utility
command through the main RS-232 port. (See section 9.4) The output may be set for data printouts, fixed-width data
output, or one of two diagnostic modes. Diagnostic modes are not used except by a factory technician.
A new configuration has been added for the printer port which enables it to output a fixed-width concentration report at
the end of the sample period, which can be used to interface to a serial data logger. This output is enabled by using the
“z” utility command through the serial port. The output format is date, time, concentration, and flow volume as shown
below.
Format in mg/m3 is:
mm/dd/yy hh:mm:ss,+99.999,+9.999
Format in g/m3 is:
mm/dd/yy hh:mm:ss,+9.999
If the APDA is set to STANDARD cycle mode, the output will occur at the top of the next hour. For example, if a
measurement is made over hour 2, then the format would be:
03/28/07 03:00:00, +00.027,+0.834
If the APDA is set to EARLY cycle mode, the output will occur at minute 55:00 for the current hour. For example, if a
measurement is made over hour 2, then the format would be:
03/28/07 02:55:00, +00.027,+0.834
9.6
Modem Option
The HORIBA BX-996 modem is recommended for use with the APDA-371, as it is designed to reliably communicate
when other modems may not. Note: the RS-232 Polarity switch on the back of the APDA-371 may need to be set to
REVERSE polarity for communication using the modem. If you are using one of the HORIBA data acquisition programs
such as MicroMet Plus or MicroMet AQ, you need only enter the telephone number of the site in the system setup menu
of the program. Multiple telephone numbers can be entered for connection to multiple remote sites.
