Power Supply The SIO-485.LPCI has the ability to provide DC power on pin 9 of the DB-9 connector to be used by the integrator in low power implementations. This power is fused at 1A and is selectable as +5, +12 VDC or no power required.
No two adapters can occupy the same I/O address. Make sure the Sealevel Systems adapter is using a unique IRQ The IRQ is typically selected via an on-board header block. Refer to the section on Card Setup for help in choosing an I/O address and IRQ.
If possible, please have the adapter installed in a computer ready to run diagnostics. 3. Sealevel Systems provides an FAQ section on its web site. Please refer to this to answer many common questions. This section can be found at http://www.sealevel.com/faq.asp.
