15. TTL SERIAL LINE
The TTL connector allows, by means of the external module TTL/RS485, to connect the unit to a network
line ModBUS-RTU compatible as the dIXEL monitoring system.
The same TTL connector is used to upload and download the parameter list of the “HOT KEY”.
16. USE OF THE PROGRAMMING “HOT KEY “
The Wing units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the
“Hot Key” and vice-versa.
16.1 DOWNLOAD (FROM THE “HOT KEY” TO THE INSTRUMENT)
1. Turn OFF the instrument by means of the ON/OFF key, remove the TTL serial cable if present, insert
the “Hot Key” and then turn the Wing ON.
2. Automatically the parameter list of the “Hot Key” is downloaded into the Wing memory, the “DoL”
message is blinking. After 10 seconds the instrument will restart working with the new parameters.
3. Turn OFF the instrument, remove the “Hot Key”, plug in the TTL serial cable and then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
- End for right programming. The instrument starts regularly with the new programming.
- Err for failed programming. In this case turn the unit off and then on if you want to restart the
download again or remove the “Hot key” to abort the operation.
16.2 UPLOAD (FROM THE INSTRUMENT TO THE “HOT KEY”)
1. Turn OFF the instrument by means of the ON/OFF key and remove the TTL serial cable if present;
then turn it ON again.
2. When the unit is ON, insert the “Hot Key” and push the UP
key; the “UPL” message will appear.
3. Push SET key to start the UPLOAD; the “UPL” message will start blinking.
4. Turn OFF the instrument, remove the “Hot Key”, plug in the TTL serial cable and then turn it ON
again.
At the end of the data transfer phase the instrument displays the following messages:
- End for right programming. The instrument starts regularly with the new programming.
- Err for failed programming. In this case turn the unit off and then on if you want to restart the
download again or remove the “Hot key” to abort the operation.
