M340 Manual Communications Port  18

RS485 wiring

The blackbody was shipped with the controller set at the following com port parameters:

 Baud: 1200

 Data Bits: 7

 Stop bits: 1

 Parity: odd

To alter these parameters, see Section 4.4.

5.3 Communication Command Set

The complete command set is extensive. For the purpose of brevity, only a few important ones

are shown here. For more information, the controller instruction manual may be requested from

LumaSense.

Command line to read current blackbody temperature:

#01R00<CR>

Controller response:

<LF>#01R00=20.0C

Command line to read current blackbody setpoint:

#01R01<CR>

Controller response:

<LF>#01R01=20.0C

Command line to change blackbody setpoint:

#01M01 0200C<CR>

In the Appendices, there is a typical QBASIC program that reads current temperature and

increments setpoint at 10 °C intervals:

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 ... 29 30
