Notes
• It is recommended that the 3C-FB, 5C-FB, or 7C-FB coaxial cable be used.
• Since the Infrared Transmitter/Receiver unit is equipped with the Live Status indicator, it is possible to
confirm whether or not the coaxial cable is correctly connected. (The indicator cannot be used for
confirmation of the unit's minimum operating voltage.)
When the indicator does not light, it can be considered that the coaxial cable is not connected or shorted.
• The Central unit has a Short Circuit indicator on its rear panel and the Central unit's short circuit protection
circuit is common to all 4 BNC terminals. If this short circuit indicator lights, locate the shorted point by
removing each distributed cord. The indicator also lights when the number of Infrared Transmitter/Receiver
units connected in the system exceeds the allowable limit.
Use the coaxial cable with a BNC connector to connect the Infrared Transmitter/Receiver unit to the Central
unit.
