CONFIGURING THE HOST COMPUTER PORT
3.3.1.1 Setting the Host Port Parameters
The host port communication parameters are configured with two 10-position
dipswitches located at the front of the adapter as shown in Figure 3–3. To select
NITP as the operating protocol, set position 1 of Dipswitch 1 up as shown in
Figure 3–10.

Figure 3–10 NITP Dipswitch Settings
The host port parameters specify the physical layer
protocol parameters and do not imply that the data
link protocols can be either asynchronous or
synchronous. Both the BDLC and NITP protocols are
asynchronous data link layer protocols.
