Hello all,
I'm dealing with three ancient data loggers, Microlink 4000, connected by GPIB and interfacing with my PC via GPIB-USB-HS.
There are no drivers for the data loggers...
Their primary addresses in MAX are displayed and I'm able to send commands but I'm unsure what to do next to begin reading the data logged by each module.
I suspect I'm simply not accessing each module's secondary address or using the wrong commands. I have scoured the web for 488.1 manuals or commands but they're not working in VISA interactive control.
i.e. (Hex 0xBFFF0015) Read error occurs whenever I'm querying the devices...
System specification:
I apologise if I've not attached enough information still very new to LabVIEW and MAX.
Please advise!
Many thanks,
JChan

I have the original manual for the software and hardware but the support for this product seems non-existant. i.e. somewhat difficult to get a specific answer.
The software manual does not show much in the way of any commands but rather their own software and some other languages (Basic, C, etc.)
I think I've found another GPIB command list which might work.

Apologies, I'm somewhat reluctant to post the manual since they're scanned documents.
I appreciate if you could point me in the right direction.
Many thanks.

I've attached some of the files included in the drivers for development purposes.

Thanks, I've reattached the drivers which come with the instrument.
Hopefully I'm not on a wild goose chase.

Ah yes, there are some commands in the file for GPIB in Basic, C, Fortran & Pascal.
DFMSCS.OBJ interface module for Microsoft C - Small model
DFMSCC.OBJ interface module for Microsoft C - Compact model
DFMSCM.OBJ interface module for Microsoft C - Medium model
DFMSCL.OBJ interface module for Microsoft C - Large & Huge models
GPIBC.H C header file - GPIB constants and function prototypes
GPIBFUNC.H C source file - GPIB transfer functions
CC8.C example C program to read Microlink CC-8 module
HP7470.C example C program to drive HP7470 plotter
Thanks for your quick reply!
The company don't seem to have a complete electronic copy. I only have the documents that came with the machine.
Kind regards.
