Hi Roger,

Are you remember me yet? Long time no contact. I have three questions:

1. DT80 can use USB memory stick, what is the maximum capacity can it manage? Is popular USB hard disk compatible as well?

2. If I want to connect DT80 and DT500 together in a network, how to interface them? Can I get all data recorded from DT500 to DT80 then downloadable into USB memory in DT80 logger?

3. Are DT already finish using DT80 with OPEC system from ADC company? Which using Gill ultrasonic and OP2 CO2 & H2O sensor.

Good morning Song Zhai,

1. DT80 uses 32 bit FAT and can address up to 8 GB memory stick, unfortunately some external hard disk may not compatible with dataTaker due to power constraint.

2. Connecting DT5xx to the DT80
   Yes we have done this, DT5xx is just another serial device and it can be connected to the DT80 serial sensor port. There is an example in the FAQ:
   http://www.thermofisher.com.au/show.aspx?page=/ContentAUS/Manufacturing-Processing/Industrial-Loggers/DataTaker/DataTaker-FAQ/Program-Code/General-Codes.html

3. Gill high speed wind sensor
   We have tested the GI R2-50 and the OPEC open path analyzer.There is a code example in the FAQ: http://www.thermofisher.com.au/show.aspx?page=/ContentAUS/Manufacturing-Processing/Industrial-Loggers/DataTaker/DataTaker-FAQ/Program-Code/General-Weather-Station-Codes.html

Cheers,

Thank you.

But if I just have one DT80, one SSP, and we need collect data from Gill's R30 also DT500 via RS485 protocol at same time, how to deal with? I think they have different protocol.

Another question:
DT50 just have RS232, if I purchase an addressable RS232 to RS485 converter unit can we use DT80 for 3 DT50's together?

Good afternoon songzhai,

The DT80 is kept very busy keeping up with the data out of the R3-50. Trying to get data from 3 DT50's would slow the system down.

I don't think this approach would work. The biggest problem would be incompatible baud rates. DT50 runs at 9600 baud and the Gill is usually set to 115200.

Cheers,
Roger
