USER MANUAL
4.4 SETTING THE NETWORK PORTS PARAMETERS
The network ports must be explicitly enabled with the CONFIGURE HIU and
CONFIGURE NETWORK MANAGER commands. The syntax for these
commands is given in Chapter 5. The network parameters specified explicitly in
these commands overrides the default values set by the dipswitches.
The choice of the host port protocol also determines whether network port
parameters can be defined on the dipswitches or through internal constants.
The BDLC protocol uses both dipswitches to define the host port parameters
and will use these internal constants for network defaults:
D Local Line media —
d 115.2K baud,
d half duplex,
d asynchronous, and
d NRZI
D RS–232–C/RS–423–A media —
d 9600 baud,
d full duplex,
d synchronous, and
d NRZ
The NITP protocol uses the values defined on Dipswitch 1 as the defaults as
shown in Figure 4–7. The network parameters are then set with Positions 2–8 of
Dipswitch 1 as illustrated in Figure 4–7. The applicable baud rate settings are
given in Table 4–4. These settings should match the settings for any other
TIWAY I network devices.
