Configured directly on the remote node backplane, the adapter maps up to 32 I\/O points across designated 1\/2-slot, 1-slot, or 2-slot addressing configurations. Physical connection over blue hose twinaxial cable enables deterministic data transfer rates up to 57.6K Baud at distances reaching 10,000 cable feet, maintaining tight scan synchronization between the host processor and remote chassis.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the backplane power supply requirements for the 1771-ASB?\u003c\/p\u003e\n\u003cp\u003eA: The adapter draws up to 1.2 A at 5 VDC directly from the 1771 chassis backplane power supply.
