Cable extension
Extension up to total 50m is possible for both emitter and receiver connecting cable
(optional) (Note 3)
Notes: 1) The beam channel is not turned OFF during muting even if it is blocked.
2) In case the blanking function is valid, the operation mode is changed.
3) The cable can be extended within 30m (for emitter / receiver) when two devices are connected in
series connection, within 20m when three devices are connected in series connection. Furthermore,
when the muting lamp is used, the cable can be extended within 40m (for emitter / receiver).
