I am doing a project using BS2 that need to send 4-20mA signal (1/3000 resolution).
The workflow is: After BS2 receiving input through RS-232 (ASCII), it will send 4-20mA signal.
I have no problem receiving ASCII data through RS232 and process the ASCII with BS2, but I have zero-knowledge about sending 4-20mA using BS2.
By browsing this forum, I found that I need DAC (16-bit for 1/3000 resolution). Can I use MAX5661? How to do the wiring between MAX5661 (or any 16-bit DAC) and BS2? How to do the BS2 code?
Pls help me.....Thx a lot
