How to configure the switch used by the module on the ISA bus
(Original Document)
About us
At a Glance
The RS 232 internal port uses 8 consecutive addresses in the input/output (I/O) space on the ISA bus and an IRQ switch. Before configuring the port, it is appropriate to determine an input/output (I/O) space and a switch on the PC using the standard utilities on Windows XP or Windows 2000.
NOTE: You are reminded that the switch depends on the communication port.
Procedure
To perform the configuration, turn the rotating micro-switch to select the switch to be used.
Step
Action
1
Select the position corresponding to the switch.
Note: This address should be the same as the one which will be configured by Windows.
Example
In this example, the TSX IBX 100 module is set to switch INT3.

The position of the micro-switch defines the standard address as follows:
