8. SerIal InTerFace
The device has a TTL-UART-interface integrated. You will find the interface on
the PCB. It can be used to extract all measured and stored data. When the
device is in normal function mode the data is sent once per second to the serial
interface. The data package consists of 7 ASCII bytes. The first 5 bytes are
information and the last two bytes are <CR><LF>. The first five bytes will either
contain temperature data or an error indication.
Examples:
1. aScII:
„121.1<CR><LF>“
hex:
„0x31 0x32 0x31 0x2E 0x31 0x0D 0x0A”
2. aScII:
„1.5<CR><LF>“
hex:
„0x20 0x20 0x31 0x2E 0x35 0x0D 0x0A”
3. aScII:
„-11.2<CR><LF>“
hex:
„0x2D 0x31 0x31 0x2E 0x32 0x0D 0x0A”
4. aScII:
„Err.1<CR><LF>“
hex:
„0x45 0x72 0x72 0x2E 0x31 0x0D 0x0A”
5. aScII:
„Err.3<CR><LF>“
hex:
„0x45 0x72 0x72 0x2E 0x33 0x0D 0x0A”

9. error meSSageS
The device can show the following error messages:
error n1
Err1
error n2
Err2
error n3
Err3
noTe:
if an error message is displayed the relay is automatically switched off.
pin 1:
GND
pin 2:
RX (input)
pin 3:
TX (output)
pin 4:
+5V (output)
If the temperature sensor all the cable to the sensor have a
short-circuit “Err1” will show in the display. The error message
will also appear if the measured temperature is lower than
–99°C.
The received data from the temperature sensor is incorrect.
If a temperature sensor is not connected, “Err2” will show
on the display. The error message will also appear if the
measured temperature is higher than +850°C.
