Note:
TLS channels are not available in ASCII protocol.
18.4.4 Switch to Binary Protocol (X)
Description: This command is used to switch temporarily into the binary mode.
Request:
'&'_<ID>_'X' CR
Response:
'$'_<ID>_'X' CR
<ID>5 Device address (5 decimal places with leading zeros)
Note: ATTENTION!! Immediately after the response, the device can only be accessed via the binary
protocol. If you want the device to work in ASCII mode again, it must be switched to ASCII mode using
the binary command for a protocol change.
After a reset or device-specific timeout, the device communicates again in the previously set mode. If the
device is to operate permanently in the binary mode, for example, the device configuration in the
EEPROM must be changed.
18.4.5 Software Reset (R)
Description: This command is used to trigger a software reset. Alternatively, the factory settings can be
restored before the reset.
Request:
'&'_<ID>_'R'_<reset> CR
Response:
'$'_<ID>_'R' CR
<ID>5 device address (5 decimal places with leading zeros)
<reset>3
010: Reset;
011: Reset with default
Note: The response occurs immediately before the reset.
18.4.6 Software Reset with Delay (D)
Description: This command is used to trigger a software reset after a delay <delay> (e.g. for firmware
update).
Request:
'&'_<ID>_'D'_<delay> CR
Response:
'$'_<ID>_'D' CR
<ID>5 device address (5 decimal places with leading zeros)
<delay>3
Delay time in seconds (max. 255)
Note: The response occurs at the start of the delay time.
18.4.7 Device Information (I)
Description: This command is used to transmit device information.
Request:
'&'_<ID>_'I' CR
Response:
'$'_<ID>_'I'_<Ser.no.>_<MMYY>_<Project>_<PartsList>_<SPlan>_<hardware>

18.4.8 Normalization of Measurement Values in ASCII Protocol
The normalization of measurement values from 0d – 65520d corresponds to the measuring range of the
respective measurement variable.
