Page 13: Changing The Gpi Output Drive
As supplied, each GPI output can drive a 24V or 48V bulb. For 5V LED drive, resistors R1 and R2 (near edge connector) must be changed from 0Ω to 680Ω 0805 surface-mount types. Note: Other adjustments on the card should normally be left in the factory default positions. 22/09/05 VDA210M User Manual V1.2... -
