Input Buffer and Output Data
The Input buffer of the LDC-3900 is 80 bytes. However, the user's <PROGRAM
MESSAGE> may be longer.
The output (response) data of the LDC-3900 is sent in blocks of up to 80 bytes in
length. It is sent using high speed DMA within the LDC-3900 Modular Laser Diode
Controller, but may be of indefinite length. Although some commands have a
definite length response, such as the MESsage? query, the response length is
indefinite because the LDC-3900 will respond to multiple queries in a single
response output. The user may enter as many queries as desired in a single input
message, and the LDC-3900 will respond to all of them in the same output
message, if possible. For example, the user may enter the following command:
"Mes?; Rad?; TEC:T?; Err?"
The response may appear in this manner:
"TEST1 ,DEC,25.0,0"
0- TEC Current Limit 8- Sensor Type Change (while output on) Event
1- TEC Voltage Limit 9- Outside of TEC Tolerance Condition
2- N/A 10- Sensor Shorted (while output on) Condition
3- High Temperature Limit 11- N/A
4- N/A 12- Software Error Condition
5- Booster Changed (while output
on) event
