5.6 Viewing Resources with Device Manager
The following instructions provide step-by-step instructions on viewing
resources used by the ESC-100 in Windows using the "Device Manager" utility. Select
Start|Help from within Windows for additional information on this utility.
1. Double click the "System" icon inside the Control Panel folder. This opens up
the System Properties box.
2. Click the "Device Manager" tab located along the top of the System Properties
box. This lists all hardware devices registered inside the Windows registry.
Additional information is available on any of these devices by click on the
device name and then selecting the "Properties" button.
3. Double click the device group "Multi-function Adapters". The ESC-100 model
name should appear in the list of Multi-function adapters.
4. Double click the ESC-100 model name and a properties box should open for the
hardware adapter.
5. Click the "Resources" tab located along the top of the properties box to view the
resources Windows has allocated for the ESC-100 match the hardware
configuration. Because PCI is a true plug-and-play bus, do not attempt to
modify the configuration values listed. Click "Cancel" to exit without making
changes.
6. The ESC-100 serial ports are also listed under the group Ports (COM and LPT).
Windows does not assign COM1-COM4 to ports addressed at nonstandard
locations. The ESC-100 ports will be enumerated starting with COM5 (or higher)
even if lower logical numbers are available.
7. Select any of the Quatech Serial Ports listed under the group Port (COM and
LPT) and click the "Properties" button. This action opens a properties dialog for
the specific COM port on the ESC-100.
8. Click the "Port Settings" tab and then click the "Advanced" button. The ESC-100
driver will display a custom Advanced Port Settings control, which allows the
ports UART compatibility mode and FIFO threshold levels to be configured.
The threshold values of full-scale for the transmit buffer and 3/4-scale for the
receive buffer shown below are optimal for most applications. Note that the
FIFO option for each of the ESC-100's eight ports is configured independently.
9. Use the Logical COM Port names to access the serial ports on your ESC-100
through your software applications. Note: The Logical COM Port name is
