<Shift> key must be depressed when Windows NT displays its logo. The system will then revert back to manual log-on via
the log-on dialog box.
6.1.5.3 Configuring Automatic/Manual Log-On
Automatic/Manual log-on configuration may be accomplished via the Configuration Editor program’s Auto Logon
dialog box. Refer to section 6.2.2.4 in this manual (page 37) for details.
6.1.6 Remote Access Service (RAS)
Windows NT Remote Access Service (RAS) must be installed if the console’s PC is used for remotely accessing other
computers or other computers remotely access it. If necessary, refer to Microsoft’s Windows NT Workstation Installation
Guide for specific RAS installation instructions.
Typically, a remote session is accomplished with either a dial-up or dedicated line modem connection. Since the console
normally requires serial communication ports COM1 (for the Enhanced Audio Enclosure) and COM3 (for the CIM), and it
may require COM2 (for touch-screen monitor), one of the following basic configurations is required for a RAS session:
•
If the C3 Maestro console is simultaneously executing during a RAS session and it utilizes COM1, COM2 and
COM3, the RAS session modem must be set-up to use a different COM port, interrupt (IRQ), I/O base address, etc.,
that in no way conflicts with the COM ports utilized by the console application.
•
If the C3 Maestro console is simultaneously executing during a RAS session but it does not require the use of COM1
(for the Enhanced Audio Enclosure) or COM2 (for touch-screen monitor), the RAS session modem may be set-up to
use either COM1 or COM2, or any other unused COM port such as COM4. COM port conflicts must be avoided by,
for example, if using COM2 for RAS (recommended), disabling the touch-screen monitor’s driver via Control
Panel’s Devices icon. In some cases, the console application’s use of the port chosen for RAS use must be disabled
via the Configuration Editor’s Hardware dialog box; see section 6.2.2.1.2 in this manual for additional information.
•
If the console application and the RAS session do not have to run simultaneously, the modem may be set-up to
utilize any available COM port.
The RAS software includes a program called Remote Access Monitor which indicates transmit (TX), receive (TX), error
(ERR) and carrier detect (CD) statuses of the remote session. This is useful when first connecting-up via RAS. Refer to
Microsoft’s Windows NT Workstation System Guide for additional details on RAS.
6.1.7 Monitor Video Resolutions and Colors
Recommended Windows NT video resolutions for use with the console application are shown in the Table 6-1 which
follows. Basically, the higher the resolution, the smaller the displayed objects appear on the monitor’s screen. Therefore, a
higher resolution screen can display more non-overlapping objects, with the compromise being smaller, harder to visualize
objects at greater eye-to-screen distances. This compromise may be of significant concern when making resolution
configuration decisions, particularly in a busy dispatch environment and/or when smaller screen size monitors are employed
such as the 14-inch units.
For best display performance the console application requires a 65,536 Windows NT color setting. A 256 color setting
will cause some display items’ colors such as the background colors on command panel buttons to appear dithered or textured
instead of solid. A sixteen (16) color setting or a monochrome color setting should never be used with the console application.
When making resolution and maximum color setting configuration decisions for a factory-supplied console system, video
memory requirements are not an issue since each PC includes 1M bytes of video memory (see Table 2-1). For non-factory-
supplied PCs, consult the manufacturer’s documentation for configuration capabilities.
Within Windows NT, both video resolution and maximum color configuration setting changes are easily accomplished
via Control Panel’s Display Settings dialog box. The factory-set configuration is a resolution of 640 x 480 pixels with
65,536 colors. This dialog box is opened by double-clicking on the Display icon in Control Panel. If necessary, refer to
Microsoft’s Windows NT Workstation System Guide manual or Control Panel’s on-line help for additional details. To enact
any changes made via this dialog box, Windows NT will request an operating system reboot. This reboot is necessary to
completely reconfigure the operating system and the PC’s video display adapter circuits with the new video setting(s).
