I am confused of what serial ports to buy for 2620XM.
In this link in figure 4 there is a network module that has 8 serial ports. But they are asynchronous/synchronous serial ports?
The link is:
If I compare these serial ports and the serial ports that I get in WIC-1t, what is the differece?
In WIC-1t the serial port is DB60 (the big one) compared to WIC-2t. If I want to have a card that has two serial ports like in WIC-1t, do I have to buy two WIC-1t cards or are there any card that has that size two serial ports?
Thanks in advance!
