(1)Setting switch "TX1"
Turn the switch to "ON" position, and the function of preventive measures to
breaking of CH1 is actuated. In the case that, when the function is in "ON" mode, the RX signal of CH1 cannot be detected during a period of about 400 ms, the transmission of TX signal from CH1 is stopped.
On the port which entered the stop transmission, when the switch is turned to "OFF" position after the circuit operation is resumed, the transmission is reactivated on receiving signals from other port. When the switch is turned to "ON" position again, the function is also reactivated.
When the function is in "OFF" mode, TX continues to transmit signals even if RX signal cannot be detected.
(2)Setting switch "TX10"
Turn the switch to "ON" position, and the function of preventive measures to
breaking of CH10 is actuated. In the case that, when the function is in "ON" mode, the RX signal of CH10 cannot be detected during a period of about 400 ms, the transmission of TX signal from CH10 is stopped.
