14.2.4 Sensor Response
!E0.975<CR><LF>
“!” is the parameter for “answer”
“E” is the parameter
“0.975” is the value for the parameter
<CR> <LF> (0D
hex
0A
hex
) is closing the answer
For processing the received commands, the device typically needs about 200 ms. For certain commands, this
time can be even longer.
14.2.5 Sensor Notification
With a notification the sensor informs the host, that the sensor or the firmware was reset.
#XI<CR><LF>
“#” is the parameter for “Notification”
“XI” is the value for the notification (e.g. “XI” firmware reset)
<CR> <LF> (0D
hex
0A
hex
) is closing the notification
!XL<CR><LF>
“!” is the parameter for “Notification”
“XL1” is the value for the notification (e.g. “XL1” laser switched on)
<CR> <LF> (0D
hex
0A
hex
) is closing the notification
14.2.6 Error Messages
An asterisk * will be transmitted back to the host in the event of an “illegal” instruction. An illegal instruction can
be caused by a syntax error with the following response:
•
“*Syntax Error” – a value entered in an incorrect format
14.3 Transfer Modes
There are two possible transfer modes for the serial interface.
Poll Mode:
The current value of any individual parameter can be requested by the host. The sensor responds
once with the value at the selected baud rate.
Burst Mode:
A pre-defined data string, a so-
called “burst string”, will be transferred continuously as long as the
burst mode is activated.
V=P
“P” starts the poll mode
V=B
“B” starts the burst mode
$=UTIEEC
“$” sets the content of the burst string
“U” for temperature unit
“T” for target temperature
“I” for internal case temperature of the sensor
“E” for emissivity value
“EC” for error code
?$
gives the burst string parameters while in
poll mode, e.g. “UTIE”
?X$
gives the burst string content while in poll mode, e.g. “UC T0150.3 I0027.1 E0.950”
Return from burst mode to poll mode
V=P
„V=P“ to be sent (it could be necessary to send the command more than one times)
14.4 Sensor Information
The sensor information is factory installed as read only values.
