3-26 VitalSense Operation - Application Program
USB Adapter
Persistent RS-232 Errors
If you still have difficulty establishing communications with the
VitalSense Monitor, it may be necessary to use a USB to serial adapter.
Some brands of laptops have demonstrated peculiar problems due to
hardware and/or driver incompatibility. The use of a USB-to-serial port
adapter will require you to install the new driver supplied with the adapter,
and this may result in successful communication.
A USB-to-serial port adapter may be purchased from Mini Mitter
Company, or your local computer store. The recommended adapter type at
this printing is the Aten
®
UC232A.
Installing the USB Adapter
1 To install the proper drivers, follow the directions included with the
adapter.
2 Connect the adapter to the USB port on your computer.
3 Use the Windows Device Manager to find the COM port assigned by
the adapter driver. See the Windows help function for instructions.
4 Once the assigned COM port is known, enter the port number in
VitalSense Application Program Setup (see “ COM Port Setup ” on
page3-7).
