Are the serial ports that come standard on the Digi Transport series DTE or DCE Serial?

Beverly McRae

Unlike the ConnectPort WAN, the serial ports on the standard builds of the Digi Transport line are DTE not DCE serial, this means that a null modem cable should be used instead of a cross-over cable.

Null modem is a communication method to connect two DTEs (computer, terminal, printer etc.) directly using an RS-232 serial cable. The name stems from the historical use of the RS-232 cable to connect two teleprinter devices to modems in order to communicate with one another; null modem communication was possible by instead using RS-232 to connect the teleprinters directly to one another.
