If you are communicating with a terminal program such as HyperTerminal
®
or ProComm Plus
®
you will need to define
the serial port configuration in the setup of the program. Set the baud rate to 9600, with 8 data bits, no parity, and 1 stop
bit. Use the terminal program’s internal dialing command sequence to dial up the APDA-371. Verify the connection to
the APDA-371 by pressing the <Enter> key until the command prompt asterisk (*) appears. If not, verify the cabling and
communications settings. Once connected, the access to the APDA-371 is the same menu driven interface as used for
the direct PC connection.

Flash Firmware Upgrades
The APDA-371 now has the capability for flash firmware upgrades. This allows the field operator to reprogram the flash
EEPROM through the serial port using the Flash Update Utility. Units with a firmware revision of 3.0 or higher can be
flash upgraded. If the unit currently has a revision lower than 3.0, the EEPROM will have to be replaced with a flash
compatible chip. The following tasks must be performed whenever firmware is upgraded or the EEPROM is replaced:
1.
Download and save all data and error logs before proceeding. These will be cleared during the upgrade process!
2.
Record the OFFSET value from the SETUP > SAMPLE screen, and the BKGD value from the SETUP >
CALIBRATE screen. A download of the settings file is advised.
3.
Update the firmware.
4.
The baud rate will default to 38400. Reset as appropriate.
5.
Recalibrate the filter temperature and filter RH sensors.
6.
Set the values of OFFSET, CONC UNITS, and COUNT TIME in the SETUP > SAMPLE screen.
7.
Set the values of CONC TYPE, FLOW TYPE, and BKGD in the SETUP > CALIBRATE screen. Review all other
APDA-371 settings to make sure they are all correct.
