†Note: The TRC function is discussed separately. See
circuit
‡Note: The DIFL#2 element is designed to operate when the DIF function runs in the
dual mode using dual channel (setting [TERM_TOPOLOGY]=2Term-Dual). That is,
the DIFL#1 element operates using the data provided with the first channel
(CH1); the DIFL#2 element operates using the data provided with the second
channel (CH2). Accordingly, the difference of the transmission delays in the both
channels will be cleared, if the communication delays in the both channels vary
depending on the time and place. For more information of the mode, see chapter
Relay application: Transmission control function
