Command 7:
Certain parameters are needed in order to calculate the QNH and QFH pressure
and to set the status settings as explained in chapter 3.3.
Command 8:
It’s possible to change the baud rate of the serial inputs and outputs. These
settings will only be active after twice the “Q” command and the ‘Save and exit menu’.
Note: When you change RS-232 baud rates, change your terminal settings as well,
change is effective once you leave the menu.
Command 9:
It’s possible to use the RS232 as OMC-2900 output as well. Command 9
enables/disables the OMC-2900 over RS-232.
Command A-D:
(re)Calibration of the analog inputs can be done by using the commands
A-D. The represented inputs are located on the extension board, therefore they need calibration
after the assembly line. Please make sure calibrated equipment is used to present the right
current or voltage.
If the presented values are way of the expected values the old values of calibration will remain.
