USER MANUAL
5.4.2 Configure HIU Command — 11
The CONFIGURE HIU command enables the HIU function/TIWAY I network
interface. It also configures the TIWAY I network parameters. This command
can only be issued once, after the adapter is reset or powered–up and the mode
configured, and must be issued before the HIU function can begin
communications.
Command: 11 ([oo vvvv])
Response: 11
Usage: CONFIGURATION
Modes: MHIU, HIU
Parameters:
oo The option number ranging from 01 to 03. These options may be
specified in any order, but may only occur once. Any options not
specified will assume the default values.
vvvv The parameter value.
The following describes the options and associated parameter
values.
Option–01 = Defines the HIU network parameters. The HIU automatically
determines the type of media card, so the host computer only
needs to specify the values discussed below. If this option is not
specified, the HIU will assume its parameters from the values on
Dipswitch 1 when using NITP and by default values when using
the BDLC protocol. This option is only required if the adapter is
configured as an HIU.
When the BDLC protocol is selected, the network port defaults
are 115.2K baud, half duplex, asynchronous, and NRZI for Local
Lines or 9600 baud, full duplex, synchronous, and NRZ for
RS–232–C/RS–423–A media. This parameter is bit mapped as
shown in Figure 5–4 with the baud rate selections given in Table
5–2.
