Power Management
The DS457 decoder/interface board has various power management options depending on the host interface.
USB (SNAPI, USB HID Keyboard, etc.) - The DS457 automatically manages its power usage, including
USB suspend mode. Additionally, when drawing power from the USB bus, the DS457 does not exceed
the USB limit of 500 mA.
SSI or RS-232 - When using SSI or any RS-232 host interface, the DS457 uses one of the following power
modes. See Power Mode (RS-232 Hosts Only) on page 6-15.
Continuous Power: The DS457 is fully awake and running, even when not in a decode session.
Low Power (default): The DS457 draws less current at idle than when in Continuous Power mode.
