DB9 port on USA-19HS
Note:
If your serial device has a different connector, you may need a converter cable or adapter to connect
your device to a DB9 port. Please contact the manufacturer of your serial device for details.
Now that you have physically connected your serial device to the Keyspan adapter, we need to con-
nect your serial device's software to the Keyspan COM port (software). Before we can do this, we
need to determine the Keyspan COM port. If you already know the Keyspan COM port, skip Step 2.
2. Open
Keyspan Serial Assistant
utility (START menu > (All) Programs > Keyspan > Keyspan Serial As-
sistant). You will be presented with the following window:
Keyspan Serial Assistant window
Alternate Method:
You can also use the
DEVICE MANAGER
in Windows to determine the Keyspan COM port. COM ports
are shown in the Device Manager under the
PORTS (COM & LPT)
section.
Write down the COM port shown in the ADAPTER STATUS tab. We will need this in the next step. You
can close the Keyspan Serial Assistant when you have noted your COM port.
Note:
COM ports are assigned on the basis of what COM ports (software addresses) are available on your
computer. Because of this, your adapter may be assigned to COM3 on one computer and the same
adapter will be assigned to COM9 on another computer.
COM port addresses can be reserved by software. Microsoft typically reserves COM1 and COM2 on
most Windows 2000, XP, and Vista computers. Devices such as internal modems, Bluetooth devices,
and other USB to serial adapters will also reserve COM ports. This topic is discussed in more detail in
the
Changing Your COM Port Address
section later in this manual.
