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.

The PA11A emulation mode requires a PTB330 that is equipped with

three barometer modules.

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 outputs messages in the PA11A format.

You can start the automatic message output with the command

R, and

stop it with the command

S. Use the SEND command to output a

single measurement message.

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

SMODE command (for example

SMODE STOP), and reset the

transmitter.
