Conflict Trouble Shooting Guide
This Windows 95
application note can be used for all ACTiSYS devices including:
ACT-IR220L ACT-IR3S+ ACT-101 cable
note will resolve most serial port conflicts for the above mentioned
ACTiSYS devices. For more detailed information about serial ports
please contact the computer system dealer or refer to your computer
In order to
use ACTiSYS serial device there must be one free serial port.
Normally this 9 or 25 pin connector is located in the back of the
computer Plug your ACTiSYS serial device into the connector and
follow the simple steps described below.
- Usually the
conflict is caused by the mouse or modem. If you have a mouse it
is usually assigned to COM1. COM2 or COM4 is usually assigned to
a modem. We recommend you use COM4 for the modem and COM2 for
the ACTiSYS serial device. You can verify which COM port is
being used by your modem by going into Control Panel
(under START in Windows 95). Then double click on the
modem icon. Next select (single click) your selection and choose
properties. From here you can see or change your Modem COM
- In most cases
the default addresses and IRQ value for the serial ports are
COM1 03F8 4
COM2 02F8 3
COM3 03E8 4
COM4 2E8 3
Note: If you
use a serial device that connects COM 1 or COM3 (or COM2 or
COM4) at the same time, neither device will work as you will
have an IRQ conflict as each pair share the same IRQ. See above
- For COM port
setting on an internal modem you will have to refer to the
manual that came with the modem. Installation varies from mfg.
to mfg. Some have jumper settings on the board, others have dip
switch selections on the outside of the bracket. Only your
manual can help you here.
- For motherboards
that have serial connections onboard, please refer to your user
manual for COM port selection
- If you have a
serial I/O card again you will have to refer to the manual that
came with the board for COM port selections.
- If you are not
familiar with hardware settings, we recommend you contact your
computer dealer or a computer technician. ACTiSYS manufactures
infrared devices for operation on a wide variety of computer
systems. Details of each system can only be found
in the manufacture manual.
