parameters of this port to match those of the Allegiant
system console port. From the
Allegiant Server
menu,
select
Transfer | Communication Setup.
Change the
COM port entry to the COM Port that is connected to
the Allegiant System. Change the baud rate to match
that of your Allegiant System. Then, click
Go Online
.
The default Allegiant System baud rate is 19200. If the
Online attempt fails, verify that the cable is connected
to the correct ports and that the communication
parameters are set correctly. The PC parameters set in
the
Transfer | Communication Setup
menu must
exactly match the parameters of the Allegiant system.
Correct any problems, and attempt to go online again.
If the Console baud rate is below 19200, it is
recommended that it be changed to a higher baud
rate. Rates of 19200 or 57,600 are recommended.
Higher rates should be used for shorter cable lengths.
If the supplied 10 foot cable is used, a rate of 57,600
should work reliably. At these high rates, handshaking
should always be enabled. Select the
Parameter table
by clicking the
Parameter
tab. If not already selected,
click the
COMM Port
subtab. Change the Console
baud as desired, and download this table by clicking
Download
underneath the table. You will be
prompted to reset the system. Reset the system by
clicking the appropriate button. Then, select
Transfer |
Communication Setup
from the
Allegiant Server
menu
and change the baud rate to match the new Allegiant
baud rate. Then, click
Go Online
.
Networking Options (Available only to Windows
NT, 2000, XP users)
On the
Communication Setup
dialog, the
Current
Host
box is used when the Allegiant is connected to
other computers using the computer network. This box
should be set to Local if the Allegiant System specified
by the Allegiant Server file is directly connected to one
of the PC COM ports. If the Allegiant is connected to
a different computer on the PC network, then
Current
Host
should be set to the name of the remote (Host)
computer.
A list of computers that are available on the network
can be seen by clicking the
down-arrow
button in the
Current Host box. When the Allegiant Server program
is first started, the only choice available in this list will
be Local. The Refresh Host List button can be used to
update the list. Clicking
Refresh Host List
causes the
Allegiant Server program to examine the network to
determine which other computers are available.
IMPORTANT:
This operation may take several
minutes — an hourglass cursor is displayed while the
operation is in progress.
When the
Current Host
box is set to the name of a
remote Host computer, then the other parameters
(COM Port, Baud Rate, Stop Bits, Data Bits, and
Handshaking) should be set to match the settings of
the Host computer.
Through the network, any number of PCs can be
connected to an Allegiant system in this manner. It is
also possible to connect to multiple remote systems
and to connect to both local and remote systems from
the same computer.
To connect PCs to an Allegiant System over the
network, follow the steps below:
1. From the Host PC (the PC whose COM Port is
connected to the Allegiant system), open a file or
create a new file of the appropriate system type
(LTC 8300, LTC 8500, etc.).
2. From the Host PC, go online with the system. In
this case, the Current Host property will be set to
Local.
3. From the remote computers, open a file or create a
new file of the appropriate system type.
4. Select
Transfer | Communication Setup
from the
menus to display the Communication Setup dialog
box. Click
Refresh Host List
and wait until the
update has finished.
5. Click the
down-arrow
to display the list of
computers on the network, and select the name of
the computer that is connected to the Allegiant
system.
6. Set the remaining parameters to match those of the
Host system, and click
Go Online
.
The LTC 8850 GUI with Allegiant Server includes a
program called
Allegiant Network Host
. An icon for
this program is included in the LTC 8850 program
group. This program can be used in a networked GUI
installation to allow computers to go online with the
