I need to connect a VSF display to a computer. The VSF datasheet has this pin out specifications (http://www.noritake-itron.com/Specs/CUK/CU2x20029SCPB-KV91B-04.pdf)
DIN-Receive EIN-Host Busy DOUT-Transmit EOUT-Module Busy
But I can not understand how to connect it to a RS232 serial port. Seems that DIN=TD and DOUT=RD but I can understand how to connect the Host Bus/Module Busy. In the datasheet I found this:
Link EIN and EOUT for XON/XOFF
But I can not understand. Isn't XON/XOFF a software flow contol?
