APPENDIX C

PA11A EMULATION MODE

This appendix describes the PA11A emulation mode of the PTB330

series.

The PTB330 series digital barometers have an emulation mode that

allows them to partially emulate the PA11A barometer. In the emulation

mode, the PTB330 series can automatically output PA11A type of

messages.

Activating the PA11A Emulation Mode

To activate the emulation mode, use the command SMODE PA11A on

the serial line to set the start mode of the transmitter to PA11A. Then

reset the transmitter with the RESET command:

>smode pa11a

Start mode : PA11A

>reset

After start-up, the barometer will output messages in the PA11A

format. You can start the automatic message output with the command

R, and stop it with the command S. The command to output a single

measurement message (P) is not available.

To disable the emulation mode, set a different mode using the SMODE

command (for example SMODE STOP), and reset the transmitter.
