OPERATING COMPONENTS

5.1

Circuit board

After removal of the housing cover, the following operating components on the circuit board
may be accessed for adaptation of the transmitter to the desired configuration.
1. Current/voltage output
2. RS232/RS485
3. Fitting of the
Network Chip
1. Current/voltage output:
2. RS232/RS485:
3. Fitting of the network chip:
4. Display:
5. Push-Buttons for calibration purposes: see Hardware, chapter 7 "Humidity/Temperature calibration"

When the device will be switched from current to voltage
output signals using the configuration software supplied,
then two jumpers must also be positioned as follows.
for current signals:
for voltage signals:
For the transition from RS232 to RS485 (network
operation) these jumpers must be removed.
For refitting to RS485, an IC must be used (available as
an option). The notch on the chip must match the
receiver slot!
These pinboards are determined for connecting the
display module.
