4. SYSTEM OPERATIONS
(1) Signal Terminal
There are two types of i.LINK terminals -Pin 6 and Pin 4. The Pin 6 has four signal lines and two power supplies. The Pin 4 has four signal
lines. The signal lines are paired. Two are for out and two for input. The i.LINK signal is sent as the differential voltage of the two lines.

(2) Cable Bias Voltage
The two output pins is always output with approximately 1.85 V DC voltage (cable bias). The cable bias voltage output from the unit is
monitored by the output destination device and detects the connection/disconnection of the device.
In the same way, the two terminals for input monitor the cable bias voltage output from the adjoining devices to detect the connection and
disconnection of adjoining devices.
