Chapter 4: Operation - Black Box IC1000A User Manual

CHAPTER 4: OPERATION

Once you install the USB to RS-232 Converter's hardware and software, it will operate continuously without requiring
further intervention on your part.
4.1 USING THE UTILITY PROGRAM
NOTE: The following instructions apply to all Windows
The configuration utility program, which is available from the computer's Start menu after you install the driver,
allows you to manage the serial port of your IC1000A.
To access the configuration utility:
1. Download the driver, following the instructions in the previous section.
2. After the driver is installed, launch the configuration utility from the USB Director Configuration Utility on the
computer's Start menu.
4.2 GENERAL TAB
The General tab in this utility allows you to perform various tasks, such as configuring the device's COM ports, setting
port flags, and tesing the ports. See the subsections that follow for additional details.
4.3 INFORMATION TAB
The Information tab allows you to review the manufacturing information pertaining to your device.
4.4 CONFIGURATION TAB
The Configuration tab allows you to reassign the physical port on your device to any available Windows COM port
number from 1 to 255 and give your device a user-friendly device name. This capability is particularly helpful if you have
more than one device.
4.5 PORT FLAG CONFIGURATION TAB
The Port Flag Configuration tab allows you to configure performance options and special functionality on a per-port
basis.
Low Latency
Normally the UART will interrupt when the receiver has been idle for 4 character times (for example, 4ms at 9600). As
long as data is being received, the UART will continue to buffer them until its internal FIFO is full (~56 bytes). This flag
causes the USB to RS-232 Converter to poll the RX FIFO for received bytes. If any bytes are available, they will be sent to
the driver without any delay.
Remap Baud
Setting the baud rate to 1200 baud results in 230400 baud.
