(3) Transmission and reception of data
As the i.LINK signals input to a certain device is output directly to the next device, the i.LINK signals are shared by all devices. This
means that the communication data specific devices are also all input to other devices.
With the i.LINK system, data by packet is attached with an address and sent. The packet data is sent to all devices and decided by the
device data corresponding to the address. NODE ID is used for the data address, but it is also possible to output the data without specifying
the address (Broadcast output).
the address (Broadcast output).
(4) Data transmission speed
The i.LINK devices has three communication speeds-100, 200, and 400 Mbps. They are called S100, S200, and S400. The devices with
fast communication speed enable to communicate with slow devices. Consequently, the S400 device is able to handle three communication
speeds of S100, S200, and S400. On the other hand, S100 devices are unable to receive nor send S200 and S400 signals.
speeds of S100, S200, and S400. On the other hand, S100 devices are unable to receive nor send S200 and S400 signals.
In the communication between devices, the packet data can be output according to devices with the slowest maximum transfer speed.
Therefore data communication is performed at the S100 speed during communication between S400 and S100.
(NOTE) Cable transfer speed restrictions
The maximum transfer speed of the i.LINK cable differs according to the cable type. With the S100 cable, the S200 and S400 signals
cannot be sent nor received. As the DV cable is a S100, be careful not to use it incorrectly.
If a cable with low maximum transfer speed is used incorrectly, the communication signal will deteriorate, resulting in improper transmis-
sion and reception, and incorrect operation of the unit.
(NOTE) i.LINK device data transfer restrictions
In the communication of i.LINK devices, the maximum transfer speed is checked mutually, and data is transferred at the appropriate
speed. If devices that are incompatible with this speed exist on the data transmission path, data may not be transferred correctly. When
connecting i.LINK, make sure there are no devices with low transfer speed on the transmission path.
