•
If jumper during switching ON the power is not closed, device communicates in accordance
with stored setting.
•
If jumper is closed during device operation, device temporarily changes its address to 00h,
it will communicate in the same communication speed as before closing jumper and will
communicate without check sum. After jumper is opened setting of address and check sum
is reset in accordance with values stored in the device.
•
Communication speed and check sum are possible to change only if jumper is closed.
•
Jumper closed and button pressed for longer than six seconds – causes restoring of
manufacturer setting
of communication protocol
, i.e. sets Modbus RTU communication
protocol, device address sets to 01h and communication speed to 9600Bd - after button press
there is “dEF” message blinking at LCD display. Six seconds later message “dEF” stays
shown, it means manufacturer setting
of communication protocol
is done.
ARION communication protocol - AMiT company
The device supports communication protocol ARiON version 1.00. For more details see file
“
Description of communication protocols of Txxxx series
” or
Communication with HWg Poseidon units
Device supports communication with HWg-Poseidon units. For communication with this
unit set the device with setup software TSensor to communication protocol HWg–Poseidon and set
correct device address. This communication protocol supports read temperature at °C, relative
humidity, one of computed value (dew point temperature or absolute humidity) and barometric
pressure at kPa (depended by device type). For atmospheric pressure correction to altitude setting
there is Users software TSensor.
Jumper and button
If communication with HWg Poseidon unit is selected, the function of jumper and button is as
follows:
•
Jumper opened and button shortly pressed – device goes to Info mode, see chapter „Info
mode“.
•
Jumper closed and button pressed for longer than six seconds – causes restoring
of manufacturer setting
of communication protocol
, i.e. sets Modbus RTU communication
protocol, device address sets to 01h and communication speed to 9600Bd - after button press
there is “dEF” message blinking at LCD display. Six seconds later message “dEF” stays
shown, it means manufacturer setting
of communication protocol
is done.
Error States of the device
Device continuously checks its state during operation. In case error is found LCD displays
corresponding error code:
Error 0
First line displays „Err0“.
Check sum error of stored setting inside device’s memory. This error appears if incorrect writing
procedure to device’s memory occurred or if damage of calibration data appeared. At this state
device does not measure and calculate values. It is a serious error, contact distributor of the device
to fix.
