9. Remember to restore the dip switch SW4 (OFF).
NOTE
Entering new linear corrections will always cancel the previous
corrections. It is advisable to write down the factory set linear
corrections so that they will not be lost by mistake.
NOTE
When using the analog output, the corrections are performed only if
the LC is activated (see LC command on page 59)
Pin assignment
In barometers with RS232/analog output, the pin assignment is as
follow.
PIN SIGNAL
1 TX with diode
2 TX/TXD/TXD inverted
3 RX/RXD/RXD inverted
4 external power on/off control
5 ground for the RS 232C
6 voltage output (0...5 VDC) / current output (4...20 mA)
7 ground for supply voltage
8 voltage output ground / current output ground
9 supply voltage (10...30 VDC)
Load resistance for the voltage output is 10...500 kΩ and for the
current output it is 0...500 Ω.
