TM-2000 & MTM-2000 User Manual
Checking IRQ Assignments
The PCI architecture is designed to allow multiple PCI cards to share an interrupt line. The TM-2000 software allows multiple
RS-485 cards to share an interrupt. However, an interrupt line which is used by an RS-485 card must not be shared with
another device. It is OK the same interrupt line to be assigned to an RS-485 card and to another PCI device which doesn't
actually generate interrupts—for example, a VGA monitor.
To check for IRQ conflicts, do the following:
Power on the TM-2000.
1.
Insert software CD into the CD-ROM drive.
2.
Reboot the system by pressing the reset button on the front panel or the power switch on the back panel.

conflict happens between the Ethernet card and the RS-485 cards.
