1-3 Connecting Fiber Amplifier Units
1-3-1 Identifying Sensors (Fiber Amplifier Units)
Fiber Amplifier Units are connected serially to the right side of the Fiber
Amplifier Sensor Communication Unit, as shown in the following diagram.
The Fiber Amplifier Units connected to the Communication Unit are identified
according to their unit numbers. Unit numbers are automatically assigned to
the Units in order from unit number 1 starting from the Unit next to the Com-
munication Unit.
Some Fiber Amplifier Units, i.e., the E3X-DA6TW and E3X-DA8TW, are
assigned two unit numbers.
1-3-2 Number of Sensors Connected
The number of Sensors (i.e., the number of Fiber Amplifier Units) that can be
connected depends on the type of Communication Unit used and its settings
as follows:
Note Fiber Amplifier Units that are allocated two unit numbers (E3X-DA6TW, E3X-
DA8TW) must be counted as two Units when counting the number Sensors.
