We are evaluating the use of Digi One PortServer TS 4 MEI to incorporate in our own product. We have successfully used Digi One RealPort in the past. I have some questions regarding this product and I have not found an appropriate e-mail address to address them to.
1) How does the PortServer TS4 MEI handle communication when in half duplex mode?
a) When does it switch between send and receive mode?
b) What happens if data arrives on both the TCP/IP port and serial port simultaneously?
c) Can it take into account the status of the RTS signal (or other signals) to determine when to send and when to receive?
2) There appear to be several different models: Digi One TS, Digi One TS H, Digi One TS Int, Digi One TS no PwrSup, Digi One TS W (Domestic) and Digi One TS W (International). It's a jungle! How can we find out the differences between all of these? As we develop custom software for our products, even tiny technical differences may be significant.
Any information highly appreciated!
