SDT
Set Down Time (ms)
Send: „SDT 50\r‟
Return: „SDT:50\r‟
RUT
Read Up Time (ms)
Send: „RUT \r‟
Return: „RUT:50\r‟
RDT
Read Down Time(ms)
Send: „RDT \r‟
Return: „RDT:50\r‟
PSRT
Program Start
Send: „PSRT 1\r‟
Return: „PSRT:1\r‟
PSTP
Program Stop
Send: „PSTP\r‟
Return: „PSTP\r‟
ECM
Enable Calibration Mode
–Power linear correction mode (in this mode, the
external analog is corrected and output after
filtering, so the response time ofAD analog is
larger than that of through mode)
Send: „ECM \r‟
Return: „ECM\r‟
DCM
Disable Calibration Mode
（
AD analog response time is less than 100 us in
this mode
）
Send: „DCM\r‟
Return: „DCM\r‟
Others
Command error
Send: „BGM\r‟
Return: „Command Err!\r‟
STA
Read device status
– Read the product status. A return value of 32-Bit
digital information. The meaning of each Bit
is as follows (undefined or „reserved‟ Bit
negligible):
Send: „STA‟
Return: „STA:4100‟
returned value 4100(Decimal) can be
converted to 0 x1004 (hexadecimal),
and then converted to binary to see
that Bits2 and 12 have been set. The
laser enable is on and the
modulation mode is enabled
Bit 0
normal operation
Authorization time
Bit 1
normal
Temperature too high
Bit 2
Emission Off
Emission On or in preparation
Bit 3
No high reflection
High reflection Abnormal
Bit 4
External AD mode=off
External AD mode=on
Bit 5
Power Correction Mode=off
