... CircLink also uses CMI code for transmitting signals, rather than the dipulse or bipolar signals that are the standard ARCNET signals. Since CMI encoding eliminates the DC element, a simple combination of a standard RS485 IC and a pulse transformer can be used to implement a transformer- coupled network.

... Datasheet 2.7 Operation and Communication Modes of CircLink TMC2072 supports only Peripheral mode, meaning communications require an external CPU. TMC2072 does not support standalone mode, which enables communications without a CPU. There are two communication modes in Peripheral mode: Free-format mode which is capable of handling a free-format packet, and Remote Buffer mode, which uses CircLink as a simple buffer. Register bits RXM01 to 31 specify the RX mode of each page and TXM specifies the mode for TX mode ...
Page 36
... Standalone mode In Standalone mode CircLink independently executes send and receive sequences without a CPU. However, TMC2072 can not use standalone mode because it does not support standalone mode. 2.7.2 Communication Mode Free-format mode Free format mode is retained from the original ARCNET specification. This mode is not optimal for real- time performance but is useful for transferring large amounts of data at once. CPU controls a series of sequence such as " ...
