ETTINGS
The DM-24+ and the DM-30+ adapters both use switches to set the interrupt, I/O address, and
MVIP clock termination. Switch blocks SW1 and SW3 determine I/O address, SW2 and SW4
determine interrupts, and SW5 determines MVIP clock termination.
Note:
Refer to the
System Adapter Appendix
for switch locations. Configure a DM-24+ or a DM-30+
only in slots 2, 4, and/or 6. Switch settings will differ depending upon the slot you wish to
configure. Refer to the following charts/descriptions:
To set the IRQ so that it is on
, refer to switch blocks SW2 and SW4. Set the corresponding IR switch
on these switch blocks to on, with all others off. For example, for an IRQ setting of 11, IR11 (switch
4) on switch block SW2 should be on; all other IR switches on SW2 and SW4 should be off.
To set the address
, refer to switch blocks SW1 and SW3. SW1 is labeled 1 through 8 (A15 through
A8). Switches in this block should always remain on, on, on, on, on, on, off, off. SW3 varies based on
address. Use the following chart:
For example, for an address of 300, A9 (switch 7) and A8 (switch 8) on SW1 should be off; all
remaining switches on SW1 and SW3 should be on.
Note:
For all configurations, switch 4 on SW4 is a reserved switch and must always remain OFF.
