The NT6D11AB/AE/AF has three sets of DIP switches. Each port has its

own bank of 10 DIP switches (SW1 & SW2) to select the port address (8

bits) and mode of operation (2 bits). SW1 is used for port 0 settings, SW2 is

used for port 1 settings. SW3 is used to select the D-channel protocol. Port

0 is used to select whether the asynchronous ESDI port is be disabled or

not. Port 1 is used to select the standard or expanded D-channel addressing

mode on the NT6D11AB/AE/AF.
