- 161 -
NOTE
Be careful not bend optical cables to a radius of 25
mm or less. Be extremely careful not to twist
them.
• Maximum number of connectable stages
Up to 16 high-speed type I/O link adapter stages can be
connected in one I/O link, while only up to five conventional I/O
link adapters (standard type) can be connected.
1) Standard type (A13B-0154-B001)
... up to 5 adapter stages can be connected in series
2) Standard type (A13B-0154-B002)
... up to 16 adapter stages can be connected in series
NOTE
It is impossible to use both high-speed and
standard type adapters on the same line.
• Power supply
The same power supply type can be used for both the standard
type (A13B-0154-B001) and high-speed type
(A13B-0154-B002).
(a) Power supply voltage: 4.75 to 5.25 V (at receiving end)
(b) Required current: 200 mA
• Installation conditions
(a) The optical link adapter enclosure is not fully sealed ; install
it with the CNC control unit in the fully enclosed cabinet.
(b) Ground the case using the case fixing screw of the optical
link adapter.
(c) The optical link adapter is light, and it may not be necessary
to mount it with screws. However, keep it from coming in
contact with other circuits to prevent possible short-circuits.
When mounting the optical link adapter in a cabinet, attach
it with an L-type fitting using the case fixing screws (M3)
of the optical link adapter.
