SOFTWARE SET-UP PROCEDURE AE/LZB 119 1894 R1A

Via Windows NT (Verifying FIFO Is Enabled)

Each PC serial communication port which supports

console operation has a very important configuration

setting—“first-in-first-out” (FIFO)—which, if not

enabled, may cause erratic console operation. Some

third-party software installation programs may disable

FIFO on one or more COM ports. In addition, changes

within Control Panel’s Ports dialog box may

unintentionally disable FIFO. Verify FIFO is enabled

for COM1 thru COM3 as follows:

1. From Windows NT Program Manager, if necessary

open the Main program group by double-clicking

on its icon:

2. Open Control Panel by double-clicking its icon:

3. Execute the Ports program within Control Panel by

double-clicking on its icon:

4. If necessary, from the Ports dialog box select

COM1: in the Ports: listing.

5. Select <Settings…> and then <Advanced…>.

The Advanced Settings for COMx: dialog box

will appear (where x = selected COM port

number).

6. Verify the FIFO Enabled check box is checked. If

not, check (enable) it.

7. Exit (return to the Ports dialog box) via two <OK>

command button clicks. Based on past experience,

<Cancel> is not recommended here, even if no

changes of any sort were required within the

Advanced Settings dialog box. If a change is

made, a prompt will appear noting that

Windows NT must be restarted. Do not restart at

this time.

8. From the Ports dialog box, select COM2: in the

Ports: listing.

9. Repeat steps 5 thru 7 for COM2.

10. From the Ports dialog box, select COM3: in the

Ports: listing.

11. Repeat steps 5 thru 7 for COM3.

12. If a change was made in step 6 (for COM1, COM2

and/or COM3), restart Windows NT at this time.

13. Continue with the following start-up procedure.

Since the console application automatically overrides

other serial port settings established within the Ports

program such as baud rate, number of data bits, etc., no

other COM port setting changes are required within the

Ports program.

Starting The Console Application

Start the console application as follows. Factory default

console application start-up settings are assumed:

1. If necessary, from Windows NT Program Manager

restore the C3 Maestro console for Windows NT

program group from an icon state.

2. Execute C3 Maestro’s Dispatch Manager program

by double-clicking its icon (shown below). If no

mouse/track-ball is available, simply use the PC

keyboard’s arrow keys to select the icon (if not

already) and then follow with an <Enter>

keystroke. The Dispatch Manager is the console’s

main on-line program:

Per the factory default configuration, starting the

C3 Maestro’s Dispatch Manager program will

cause it to automatically start two (2) other on-line

programs which are required for (normal) console

operation. The first is the Communications

Interface program; this program handles the serial

control data messages to and from the CIM and

Enhanced Audio Enclosure. The second program is

the GUI—the console’s Graphical User Interface.

3. Continue with the database initialization

procedures which follow.

In some specialized applications, automatic start-up of

the GUI is not desired. See “Start-Up Options” on page 44

for additional information.
