1 wire half duplex UART

Is there a NI cDAQ module that I can purchase for configuring in 1 wire half duplex mode as developed by Maxim. (not RS485 2 wire half duplex)
I could probably achieve this with a tri-state DIO module, but not sure if there is one?
or RS232 module with tri-state capability?

Hi sparkeyx,


Unfortunately, I don't think we do a C series module that will tri-state but we do other High Speed DIO cards which do support this property. See here.
