A graphic representation of a daisy chain A daisy garland, a chain of daisy flowers A series of devices connected in a daisy chain layout. In electrical and electronic engineering, a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring, [1] similar to a garland of daisy flowers. Daisy chains may ...
A DMX512 network employs a multi-drop bus topology with nodes strung together in what is commonly called a daisy chain. A network consists of a single DMX512 controller – which is the master of the network — and one or more slave devices .
Sending data from sub to main may use the opposite clock edge as main to sub. Devices often require extra clock idle time before the first clock or after the last one, or between a command and its response. Some devices have two clocks, one to read data, and another to transmit it into the device. Many of the read clocks run from the chip ...
An 8 pin circular connector is used to connect (or daisy chain) AISG devices. AISG consortium has released C485 standard for this RS-485 connector. This standard specifies the mechanical dimensions of the connector more tightly than the previously used standard (IEC 60130-9 - Ed. 3.0 standard with screw-ring locking ring).
It is a way to connect instruments in a manufacturing plant. A fieldbus works on a network structure which typically allows daisy-chain, star, ring, branch, and tree network topologies. Previously, computers were connected using RS-232 (serial connections) by which only two devices could communicate.
The daisy chain cable configuration means that a message walks the chain until it reaches the target device identified in the data packet. Responses then walk the rest of the way down the chain and back up again to reach the system. Some packets may be broadcast to all devices. A command data packet consists: Address byte (1) message header

In JTAG, devices expose one or more test access ports (TAPs). The picture above shows three TAPs, which might be individual chips or might be modules inside one chip. A daisy chain of TAPs is called a scan chain, or (loosely) a target. Scan chains can be arbitrarily long, but in practice twenty TAPs is unusually long.
