5. Signalling
DIODA_USB
– diode closer to USB interface
DIODA_RS232 – diode further from USB interface
After diode supply is on both diodes light for about 0,5 second.
DIODA_RS232
Event / State
„Adapter" isn't supplied.
„Adapter" is supplied.
Transmission is in progress on RS232 receiving line
DIODA_USB
Event / State
Pendrive is disconnected or unidentified or full
Pendrive is ready
Pendrive with configuration file is connected and all parameters
are recognized correctly
Pendrive without configuration data. Configuration file has been
created with default data.
Pendrive with configuration file but one of the following problems
occured:
- configuration file is too big
- unidentified parameter in configuration file
- identified parameter has incorrect value
Data portion saved on Pendrive
Data portion saved on Pendrive but there is no free space
available
6. RS232C commands
The whole transmission from RS232 port is saved on Pendrive. Exception is situation
when byte with 0x10 value shows up. Device recognizes this as a marker – successive bytes
are interpreted as a command for the device. Device ends interpreting successive bytes as
command after 0x10 sign shows up again. Following command are recognized:
l(/)– main catalog listing
o(/plik.txt) – readouts „plik.txt" file by RS232 interface
d(2010-04-11) – data setting
c(08:00:00) – time setting
