Telegram:
The following parameters of the telegram to be transmitted can be determined in this menu:
●
Data rate can be set between 0.5Kbit/s to 40Kbit/s in 1Kbit/s step
●
Preburst can be defined between 8 bits to 1000 bits in 8 bit step
●
Testword is the data content of the telegram up to 4 data bytes length.
Note:
All the information in this menu is based on the Manchester coding scheme.
Programmable Push Buttons:
This section lists the possible functions of the three buttons on board:
●
Single telegram
●
Continuous telegram
●
Single pattern
●
Continuous pattern
●
Continuous preburst
●
Continuous carrier (unmodulated)
Pattern:
For the pattern, the following parameters can be set:
●
Data rate can be set between 0.5Kbit/s to 40Kbit/s in 1Kbit/s step,
●
Pattern length can be set between 8 bits to 256 bits in 8 bits step
●
Pattern data
Note:
The construction of the Pattern consist only of the determined bits due to the configuration of the Pattern menu,
so without Preburst the pattern configuration is not Manchester coded.
Application:
If this menu is selected, a simple illustration of the application circuit of the ATA5749 is displayed (see
).

●
After programming the parameters, the transmitter board can be unplugged from the interface on the microprocessor
board.
●
Insert the lithium cell into the battery holder of the transmitter board.
●
The transmitter board is ready for verification.
