Connecting to the host controller via standard twinaxial cable, the module manages up to 32 I\/O points across designated 1\/2-slot, 1-slot, or 2-slot addressing matrix configurations. Firmware flash compatibility ensures synchronized communication protocols at baud rates up to 57.6K Baud over distances reaching 10,000 cable feet without compromising backplane scanning speed.\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\/E?\u003c\/p\u003e\n\u003cp\u003eA: The module draws 1.0 A at 5 VDC directly from the 1771 chassis backplane power supply.
